TE KPSI 705 Submersible Hydrostatic Level Transducer

The KPSI 705 is a submersible hydrostatic level transducer specifically designed to meet the adverse environments encountered in wastewater applications. This suitably-sized transducer features a wide sensing area comprised of a PTFE-coated elastomeric diaphragm for reliable operation in highly viscous or slurry environments. All KPSI Transducers utilize a highly accurate pressure sensor assembly. The assembly is integrated with supporting electronics in durable waterproof housing constructed of 316 stainless steel or titanium. The attached polyurethane or ETFE electrical cable is custom manufactured to specifications and includes para-aramid synthetic fiber members to prevent errors due to cable elongation, and a unique water blocks feature that self-seals in the event of accidental cuts to the cable. Each vented reference transducer is shipped with our latest Superdry Vent Filter that prevents moisture from entering the vent tube for at least one year without maintenance, even in the most humid environment.
