KPSI 342 Series Pressure Transducer

Description: The MEAS KPSI 342 is a ± 0.25% FS TEB accuracy, 0.75″ diameter submersible hydrostatic level transducer that combines sensor competencies with the latest in Application Specific Integrated Circuit (ASIC) technology. Implementation of the ASIC provides unmatched sensor compensation over the entire operating range of the pressure sensor. The Total Error Band specification (± 0.25% FS) over the complete operating temperature range (-20 to 85ºC) eliminates the user having to combine multiple performance specifications to understand the total accuracy of the transducer. All MEAS 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 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 a SuperDry™ Vent Filter that prevents moisture from entering the vent tube for at least one year without maintenance, even in the most humid environments.

Features:

  • Submersible Level Transducer
  • 0.75″ Small Bore Diameter
  • ±0.25 FS Total Error Band Accuracy
  • ASIC Technology
  • Two Year Warranty
