KPSI 750 Series Pressure Transducer

Description: The MEAS KPSI 750 is a submersible hydrostatic level transducer with a 2.75″ elastomeric diaphragm and protective cage 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 MEAS KPSI Transducers utilize a highly accurate pressure sensor assembly. The assembly is integrated with supporting electronics in a durable waterproof housing constructed of 316 stainless steel or titanium. The attached polyurethane or Tefzel® electrical cable is custom manufactured to MEAS specifications and includes Kevlar® 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 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.

Features:

  • Non-Fouling Submersible Level Transducer
  • Wide Mouth Protective Cage
  • Non-Clogging 2.75″ PTFE Coated Elastomeric Diaphragm
  • ±0.25% FSO Static Accuracy
