Request Information Favorite
The KPSI 745 Submersible Hydrostatic Level Transducer is specifically designed to meet the rigorous environments encountered in a slurry or highly viscous application and can be installed in a 4” pipe. 

It provides precision depth measurement under most hostile conditions. Every KPSI Transducer utilizes a highly accurate pressure sensor assembly specifically designed for hostile fluids and gases. The assembly is integrated with supporting electronics in a durable waterproof housing constructed of 316 stainless steel. 

The attached electrical cable is custom manufactured and includes para-aramid synthetic fiber members to prevent errors due to cable elongation, and a unique water block feature that self-seals in the event of accidental cuts to the cable. Each transducer is shipped with our SuperDry Vent Filter that prevents moisture from entering the vent tube for at least one year without maintenance, even in the most humid environments.
