TE KPSI 720 Hydrostatic Level Transducer

The KPSI 720 is a submersible hydrostatic level transducer specifically designed to meet the rigorous environments encountered in liquid-level measurement and control. It can be configured to perform to specifications under the most adverse, reactive 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 durable waterproof housing constructed of 316 stainless steel or titanium.

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 vented reference transducer is shipped with a Superdry Vent Filter that prevents moisture from entering the vent tube for one year without maintenance, even in the most humid environments.
