All-in-one sanitary conductivity sensor

A conductivity sensor measures the ability of a liquid to conduct electrical current, which correlates with the concentration of ions in the solution. This measurement is vital for monitoring the purity or concentration of solutions in various industrial processes.

Conductive level sensors are designed to monitor the filling levels of conductive liquids in containers, tanks, and silos. They are pre-destined for use in the food industry. They detect the conductivity and concentration of different media and can differentiate between e.g. cleaning agents, rinsing water, and the food product. This means that it is not only possible to constantly track the product but also to reduce the waste of product and rinsing water – all possible without making adjustments to the sensor.

Benefits of the LDL sanitary conductivity sensor

   
Improve process quality and efficiency with precise concentration measurement   Increase machine availability with reliable sensors   Simplify installation with compact, plug-and-play design
  • Verify effective chemical concentrations with continuous conductivity monitoring to guarantee food safety.
  • Replace time-based rinsing with real-time measurement and run cycles only as long as needed to save time, energy and cost.
  • Reduce the risk of residual chemicals in final rinse water with high-resolution digital conductivity measurements that adapt to both rinse water and chemical ranges.
  

  • The LDL conductivity sensors' fully welded stainless-steel housing (IP68/IP69K) eliminates moisture ingress, reducing drift and electrical failures.

  • Robust PEEK probes resist cracking during thermal cycling in CIP processes.
  • No cord grips or terminal chambers, eliminating common failure points in washdown environments.
  
  • All-in-one transmitter eliminates the need for separate evaluation units, reducing cost and complexity.
  • Factory-calibrated and ready to use out of the box.
  • Standard M12 connectors and digital communication enable fast, plug-and-play commissioning—no wiring terminal chambers or probe pairing required.
  • Compact design and multiple process connections fit easily on small skids.

Factory Calibration Certificates can be downloaded at no cost from our website with the sensor serial number.
