UWT’s Rotary Paddle switch Rotonivo® RN 3002 with rope extension for point level measurement

Limit detection is required in most silos and containers to avoid overfilling or unnecessary downtime. The sensor needs to deal with an assortment of process conditions within a wide range of industries.

Contingent upon the necessities, the Rotonivo® rotary paddle switch is utilized as a full, demand or empty detector in storage silos or process vessels and is suitable for use in almost all solids. With its simple electromechanical measuring principle, it can also be adjusted for extraordinary process conditions.

A motor-driven shaft causes the vane to rotate. Once the material level reaches the vane, thereby preventing further rotation, this creates a torque, which is converted via a switch to an electric signal. Once the vane is free again of the material, the output signal is reset, and the motor-driven shaft rotates again.

This dependable and maintenance-free limit switch for safe level detection in bulk solids has international approvals for use in gas and dust hazardous areas and is also certified to SIL

The RotoNivo offers a universal voltage power supply, 24VDC to 220VAC. It can be connected to the same unit without any alterations being made and with the absence of additional power supply to the unit, for example in very old plants, is completely nullified. This makes it easy for a processing plant to keep one version in stock that can be used in various applications on different parts of the plant.

UWT suits the unit to your application, to ensure complete reliability and effectiveness.

CHEMICAL SAVINGS DURING CIP

CIP-cleaning in the food processing industry

CIP-cleaning facilities are primarily used in those installations wherever supreme necessities are demanded for hygiene and product safety, such as dairies, breweries and in food production. Throughout this process the complete production facility, including tanks and conducts, are purged and rinsed with cleaning agents and water in several cycles.  The aim of Cleaning-in-Place (CIP) is to remove product residues and microorganisms from all wetted surfaces inside tanks, pipework and filling machines while not disassembling the plant. To warrant optimum and economical cleaning, all parts in direct contact with the product must be made according to the principles of hygienic design.  Anderson-Negele’s motto “Hygienic by Design” is an expression of commitment that sensors fulfill this superior demand of the food processing industry in an exemplary manner.

Sequences of a CIP-cleaning within the example of a dairy

The CIP cleaning process takes place in several coordinated process steps. In the first step remains of the product in the installation are extruded and adhering particles removed in the pre-rinsing process. In the next steps, organic traces are eliminated with caustic and mineral deposits by use of acid. Subsequently, the facility is rinsed with fresh water and thus prepared for the next production step.

  1. Pre-rinsing (water)
  2. Cleaning (caustic)
  3. Mid-cycle rinse (water)
  4. Cleaning (acid)
  5. Rinsing (freshwater)

 

Optimization of the CIP Process

A CIP cleaning process in commonplace applications lasts between 60 and 90 minutes. The operator of a production facility consequently suffers from downtime in production capacity leading to a loss of products, and from increased cost for the consumption of water, energy and chemicals.

The hygienic design of the complete production facility and automatized processes are key factors for a reduction of the cleaning cycle times and for an increase in the efficiency and productivity of the process itself. Being an experienced specialist for sensor technology in hygienic environments, the sensors and process connections from Anderson-Negele are perfectly adapted to the requirements of the food industry and ensure the safe and economical cleaning of the facility and installations.

Why Morton Controls together with Anderson-Negele’s ILM-4 could help you

 The analysis of the return media is one of the most important steps for an environmentally friendly and cost-efficient process. The ILM-4 inductive conductivity meter plays a central role in precisely determining the phase separation: during the discharge of the liquids at each cleaning stage the media are differentiated with cost-saving accuracy.  Re-usable cleaning agent that flows off after cleaning can thus be returned to the tank to the maximum possible degree. In a separate, internal circulation and for permanent optimum cleaning result, its concentration is adapted to the specified ideal value by re-dosing with detergent and fresh water in the cleaning agent tank. The ILM-4 conductivity meter also ensures the highly precise measurement of conductivity and temperature required here.

Inductive Conductivity Meter ILM-4

The ILM-4 is designed for hygienic applications in food-, beverage- and pharmaceutical industries and controlling of CIP processes (e. g. phase separation detergents/water). The ILM-4 is currently equipped with the IO-Link in parallel.  IO-Link offers important benefits over analog technology when it comes to reliably controlling the entire process technology with a variety of measuring points, control and operating elements.

FEATURES/ADVANTAGES

  • CIP/SIP cleaning up to 150 °C/maximum 60 minutes
  • Wear-free, inductive measurement
  • In contrast to conductive measurement procedures, no problems with electrode deterioration or polarization.
  • Accurate measurement through compensation of temperature influences.
  • High reproducibility of ≤ 1 % of the measurement value.

Conductivity sensor with IO-Link

The ILM-4 conductivity sensor with IO-Link is a big step to industry 4.0 in hygienic process technology.

Proven industry standard now also for hygienic and aseptic applications

IO-Link offers advantages in process control and monitoring. The ILM-4 conductivity sensor, the first of a whole range of measuring instruments to be equipped with an additional IO-Link interface, is a well-known and proven conductivity sensor on the market. This will be followed in due course by the sensors ITM-51 for turbidity, NSL-F for level, L3 for pressure and D3 for differential pressure and volume, all based on the modular platform with fail-safe plug-and-play technology with standard cable for time-and-cost-saving installation and set-up.

The (R)evolution of conductivity measurement

IO-Link offers significant advantages over analogue technology when it comes to reliably controlling the entire process technology with many measuring points, control and operating elements. Set-up and installation are easy and cost-effective. A three-pole standard cable is sufficient for the signal transmission and power supply itself. In practice, point-to-point connections are made at field level from various sensors to collection points, so-called IO-Link masters, and from there via Fieldbus system to the control centre.

 

Simple data transfer becomes intelligent communication

With IO-Link, data streams in the opposite direction towards the sensors are now also possible. In this way, the status of the sensor can be checked and specifically queried at any time. This makes it possible to detect potential faults, signs of wear or an increased risk of failure at an early stage and helps to avoid production downtimes.

“Plug-and-play” takes on a whole new meaning

Sensor replacement of the ILM-4 with IO-Link becomes easier and safer than ever before and can be carried out independently, at any time and by any employee without any programming effort. The device configuration of each connected sensor can be stored in the IO-Link Master. Immediately when plugged in, the new sensor is automatically recognized, configured and parameterized by the IO-Link Master.

The new dimension in hygienic measuring technology is digital and analogue, compact or remote. It is: modular

ILM-4 conductivity transmitter with IO-Link creates planning security and flexibility for status control and sensor diagnostics for preventative maintenance avoids production downtime.  The combination with the modular platform, with the separation of sensor and electronic unit in the optional remote version, creates a unique constellation of hardware and software that is unparalleled in flexibility, simplicity and system compatibility.

PETROCHEMISTRY: CHLORINE-ALKALI ELECTROLYSIS

/0 Comments/in , /by

PETROCHEMISTRY 

 CHLORINE-ALKALI ELECTROLYSIS

The chlorine-alkali electrolysis is an important procedure in the chemical industry. The products chlorine, hydrogen, hydrochloric acid and caustic soda are generated from sodium chloride. There are three manufacturing methods: the diaphragm, the membrane and the amalgam process.

The LiquiSonic® analyzer provides an advantageous utilization in the varied process steps of the three methods. Foremost, the customer gains the advantages of a reduction in raw material and energy consumption, as well as an increase in the yield.

 

LiquiSonic® measuring points in the processes of the diaphragm method of the chlorine-alkali electrolysis

 

Preparation of end products

1.1  Caustic soda concentration

The market ready caustic soda (NaOH) typically has a concentration between 45 wt% and 50 wt%. Since NaOH gained from electrolyzer cells only yields a concentration range between 12 wt% and 33 wt%, it is concentrated in cascade evaporators.

If together with NaOH the solution contains NaCl (diaphragm method), the excess salt in the caustic soda precipitates in a crystal form during the evaporation. This way, the NaOH-concentration is elevated to 45 wt% and 50 wt%.

The LiquiSonic® analyzer continuously determines the concentration of caustic soda at any time after evaporation. A subsequent dilution of the caustic soda to a customer specific product concentration, can also be monitored.

ADVANTAGES:

  • Continuous concentration monitoring of the caustic soda
  • Reduction in the energy costs during the evaporation process

1.2 Chlorine gas drying

Water content needs to be removed from the chlorine gas before it is further processed as its corrosives elevate at a moisture content of over 30 ppm. For the drying, the chlorine gas is routed into the absorption towers, where the water content in the chlorine gas is absorbed with highly concentrated sulfuric acid (80 – 99 wt% H2SO4).

The effectiveness of this drying process significantly influences the productivity and quality of the gas. Therefore, a reliable measurement of the H2SO4 concentration is vital. The LiquiSonic® analyzer offers a continuous and safe monitoring of the H2SO4-concentration, in opposition to conductivity and density measurement.

ADVANTAGES:

  • Elimination of labour intensive sampling
  • Continuous monitoring of H2SO4-concentration
  • Clear concentration determination signal between 80 wt% and 100 wt% H2SO4
  • Ensuring the desired Cl2 dryness to avoid corrosion in the system

1.3  Hydrochloric acid production

The chlorine gas that is generated on the anode of the electrolyzer with the added hydrogen form the base materials for the synthesis of hydrochloric acid. Both gases are fed into a burner and react to form hydrogen chloride. Subsequently, the formed HCI-gas streams from the burning chamber into the integrated isothermic falling-film-absorber. Here, the gas is absorbed with the help of water or diluted acid, whereby concentrated hydrochloric acid (37 wt% HCI) is formed.

Using the LiquiSonic® analyzer, a continuous monitoring of the hydrochloric acid concentration is possible. This allows for deviations to be recognized from the target concentration and to react accordingly.

ADVANTAGES:

  • Continuous concentration monitoring of hydrochloric acid (20-40 wt% HCl)
  • Ensuring an extremely precise target concentration

Advantage of sonic velocity as compared to conductivity and density

Precise Measurement with Sensotech’s Liquisonic Sensors

/0 Comments/in /by

For a more precise and quicker measurement of concentration and density, look no further than the Sensotech Liquisonic Sensors.

 

In particular Sensotech have had much success in the many sectors from chemical to the  brewing industry. While they use a standard system, there is also fine-tuning to customise the solution to the specific food industry specifications and hygienic requirements.

 

INSTALL AND FORGET

It is rare in an industry, where keeping tabs is the norm, to find a company that promotes walking away and letting the system manage the process alone. And that really is the case here! Sensotech’s Liquisonic sensors are that in tune, that once they have been set up correctly, they will monitor continuously.

 

Multiple signals are sent out every second and combined into one compensated signal. The temperature of the medium and the drifts are taken into account during single measurements. No matter what is happening with the conductivity and colour of the medium, the measurements continue. They are also resistant to pressure shocks.

 

The Liquisonic sensors are manufactured to be maintenance and drift-free for a period of 15-20 years. If you were concerned about drift in measurement before, no need to with SenorTech.

 

WHAT IS THE UNIQUE CONCEPT BEHIND THESE SENSORS?

sensors

The fast reaction time of these sensors using absolute sonic velocity as a well-defined and retraceable physical value means phase separation is quicker than before, with more accuracy. You are getting a reproducible physical signal that is quite unique handling temperature rangers of  up to 180 °C or 200 °C and can be use in explosion areas as well.  Solid rugged sensors for a precise and fast density and concentration measurement using absolute sonic velocity as a well-defined and retraceable physical value.

The positioning of the Liquisonic sensors is key in the application, be it in the main vessel or piping. The sensors are available to suit your process connections, such as tri-clamps, varivents or flanged.

The electronics can be housed inside a enclosures form polyester to stainless steel casing (IP 69) or in an existing cabinet.

 

THE STORAGE OF DATA

 

The Sensotech  controller can have up to four sensors connected for management of up to 32 (optional 99) products with an output of concentration and temperature, trend chart for a fast process course overview with  simple parameterization, e.g. of periphery analog and digital outputs, fieldbus, and Ethernet.

D3 Differential Pressure & Level Transmittor

/0 Comments/in /by

Focusing on the Food, Beverage, Dairy and Life Sciences industry, we bring you Anderson-Negele’s D3 Differential Pressure and Level Transmittor.

Using the Modular Platform of Anderson-Negele sensors and the technology of L3 it has a parallel display of differential pressure and head or system pressure in the display and two mA output interfaces. The electronics using digital signalling to avoid negative impact of temperature changes reduces the effects of process and ambient temperature changes quite significantly. One of the elements we like about the D3 is that it comes ready to use out-of-the-box and the simple setup and programming is just that – simple.  You can mount the D3 transmittor display direct or you can mount the two sensors remotely and insuring a reliable remote wire cabling.

Take a look at some of the applications where this transmittor has worked well.

THE RANGE OF APPLICATIONS FOR THE D3 DIFFERENTIAL PRESSURE AND LEVEL TRANSMITTOR

 

  • In yoghurt culture vessels for Level monitoring
  • In fermentation vessels for Level monitoring
  • In Mashtuns for grain bed monitoring
  • Across membranes for pressure drop measurement

WHAT ARE THE MAIN FEATURES?

 

As mentioned, the setup couldn’t be easier with the user interface display.  You are provided with two analogue outputs, the top or bottom pressure and the differential pressure output.  In addition, the temperature compensation which will minimise any errors in extreme temperature changing applications plus simple and reliable remote wire cable avoid frequent recalibration

 

Should there be a need to replace or repair components, this can be done in the field with ease and no interruption to the work process as there are no capillary issues!  On inputting the product and tank information, you will receive accurate mass and volume output due to the integrated tank tables.  The patented dual o-ring seals give you IP69K ingress protection and you can look forward to the dual loop output provided by the Hart 7.0 graphical and communication LCD display.

 

WHAT IS THE MEASURING PRINCIPAL OF THE D3 DIFFERENTIAL PRESSURE AND LEVEL TRANSMITTOR

 

In the D3 system, each sensor uses an internal piezo-electric signal converter and a temperature sensor to measure the pressure and temperature of the capillary fill.  The electrical signal of the pressure converter and the resistance of the temperature sensor are measured and converted to a compensated pressure value in the pressure fitting. Both signals are transferred digitally to the head. They are then output in a standardized 4…20 mA and HART 7.0 signal for the differential pressure and in a 4…20 mA signal for the top or total pressure.

 

Where you have level applications that have pressure and/or vacuum conditions, we highly recommend the D3 Differential Pressure and Level Transmittor from Anderson-Negele.

MORE ON THE T30

 

There are two emitters and two detectors, which are set at 90 degrees to each other.  As they pulse in sequence, two detector currents are produced, one from the detector at 90 degrees to the emitter (scattered light) and one from the detector opposite the emitter (attenuation). A Ratio-metric four beam signal processing compensates for changes in optical properties of emitters and detectors due to ageing and surface coating.

 

A standard built-in cleaner is available with the T30 submersible turbidity sensor from Quadbeam.  The recommended cleaning method is with high pressure air with an optional biocide included. To protect the sensor fingers from impact, stainless steel support rods are designed to lift and protect the sensor fingers in rugged applications.
