  • Product Info
  • Literature


The PWT Series wet/wet differential pressure sensors provide reliable, accurate measurement and control of many applications, including pump differential pressure, chiller/boiler differential pressure drop, and CW/HW system differential pressure.


  • The PWT Pressure Sensors incorporate microprocessor profiled sensors for exceptional accuracy and reliability.
  • Field-selectable 4-20 mA, 0-5 Vdc, or 0-10 Vdc output.
  • Jumper-selectable slow or fast response time.
  • Switch-selectable pressure ranges.
  • The jumper-selectable output switch for normal (4-20 mA) or reverse (20-4mA) operation provides application flexibility.
  • Rugged, die-cast enclosure provides NEMA 4 sealing.
  • Jumper-selectable port swap feature.
  • All models offer both push button and digital input to zero the output.
