D3 Differential Pressure & Level Transmittor

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.
