How to get the most from your Feed Plant

UWT in partnership with Morton Controls have the solutions for the Animal Feed Industry

The process and storage environments within the feed industry sector often have factors such as moisture, vapor and fat to consider which cause the materials to have caking tendencies.  In order to withstand and remain fully operational, UWT devices have special coatings which in turn provides the customer with economically viable solutions.  With years of experience within the feed industry and the continual research and development of measurement technology, UWT sensors offer wide and innovative versatility.

Reliable measurement technology for versatile solutions within the animal feed industry

The production of high-quality animal feed and pet food is an important economic growth sector. As well as livestock feed, this sector also includes pet and sports animal nutrition.

The requirements of animals in terms of nutrition are diverse and so a variety of mixed feed formulations is manufactured. Accordingly, the focus of the measuring technology equipment in the manufacturing plant is on the ability to easily and quickly adapt to the varying processing conditions. The formulation of a compound feed is based on the particular use for which the product is intended. Similarly, the use of appropriate measuring sensors is in accordance with the relevant requirements of the application.

The level sensor is an indispensable element of the technical equipment within a modern feed production plant for the detection and monitoring of levels and limit levels within the different process stages. All UWT devices are designed to allow easy integration into the various processes and are characterized by being completely maintenance free in accordance with the principle of “install and forget “.

1. UWT Portfolio

UWT provides sensors for the measurement of level and limit level in bulk solids and liquids. Depending on the medium and application, different measurement techniques are used as well as a range of complete systems for level monitoring and visualization. The product lines include not only an economic standard but also particularly high grade, premium versions. UWT devices are completely maintenance-free and, importantly, carry international certificates.  All limit switches are available with universal voltage electronics as standard or as an option.
