KPSI 335 0.05% Submersible Liquid Level Transducer
Brand: TE ConnectivityThe KPSI 335 is a submersible hydrostatic level transducer specifically designed for small bore applications and to meet the rigorous environments encountered in ground water level measurements.
This transducer provides repeatable, precision depth measurement under most adverse conditions. All 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 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 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.
