Keeping an eye on the tank: L3 pressure transmitter from Anderson-Negele

If you cannot see what is going on inside tanks in food or pharmaceutical production, the processes are almost impossible to control. To ensure process reliability, the tank contents must be continuously monitored. The decisive factor is precision. The L3 pressure transmitter from Anderson-Negele stands out with its unrivalled measuring accuracy.

Filling and mixing processes in production plants in the food and pharmaceutical industries can only be carried out precisely if it is absolutely clear what condition the tank contents are in. Standard pressure sensors are not enough to meet the particularly high precision requirements of these specific industries. Small containers with large temperature differences are a particular problem for pressure sensors when it comes to accuracy.

A high bar for hygienic measurement technology

Bachofen’s technology partner Anderson-Negele knows all about the production processes of food manufacturers, dairies, breweries and manufacturers of pharmaceutical products, and about the stringent requirements for process reliability and hygiene. The L3 pressure, level and volume sensor raises the bar even higher for measuring accuracy in tanks.

Unrivalled accuracy even with turndown and temperature fluctuations

The hydrostatic pressure transmitter, which is particularly suitable for level and volume measurement, delivers highly accurate readings even at low measuring heights and changing temperatures. The integrated tank linearisation with additional density compensation guarantees highly accurate indication of volume or mass in kilograms, litres or percentages.

High flexibility, easy maintenance and use

The L3 pressure transmitter is not just impressive in its accuracy, but also in its ease of maintenance. If the membrane is damaged, the component can be replaced without recalibration thanks to the modular design. Neither does the measuring cell have to be readjusted if it is replaced, because it is digitally linked to the electronics and automatically loads its calibration values. For use in tight, inaccessible spaces, there is a two-part version where the electronics and display can be positioned in a clearly visible place separately from the measuring element. Programming and calibration on the neat and tidy display are just as easy as the installation. Communication can take place via HART or IO-Link.

Bachofen’s specialities include impressive measurement solutions for the food and pharmaceutical industries. They are based on product- and industry-specific application expertise, which is also supplied in the personal advice given to system operators.
