KPSI 300DS Analog Water Level Sensor

Brand: American Sensor Technologies Inc
Request Information Favorite
The KPSI 300DS submersible hydrostatic level transducer is specifically designed for small bore applications and to meet the rigorous environments encountered in deep water level measurements.

This transducer provides repeatable, precision depth measurement under most adverse conditions. Every KPSI Transducers utilize 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.
