Baumer – CombiLevel – PLP70S

CombiLevel_Potentionmetric Level Sensor

Brand : Baumer

The Baumer CombiLevel PLP70S is a continuous level sensor that uses potentiometric measurement technology to deliver precise and reliable level data for liquid process media, including those with very low conductivity (≥ 5 µS/cm). Designed for use in both industrial and hygienic applications, the PLP70S provides accurate level measurement over a range of tank sizes and is robust against media that is foaming, pasty, or adhesive, making it suitable for food, beverage, pharmaceutical and general fluid handling environments.

Equipped with a compact design and high‑quality wetted components such as PEEK and AISI 316L stainless steel, the sensor supports IO‑Link digital communication and conventional 4…20 mA output for seamless integration into modern automation systems. Its configurable measuring range and stable performance in dynamic conditions allow for reliable continuous level monitoring and control with repeatability and fast response.
