KPA Series - Industrial/OEM Pressure Transmitter


  • Pressure Ranges from 0-50 PSIG through 0-10,000 PSIG
  • Approved Explosion-Proof for Class 1, Div. 1 and Class 1, Div. 2 Hazardous Locations
  • One Piece 316L Stainless Steel Sensing Diaphragm With No Welds, O-rings or Seams
  • Rugged Factory-Sealed Case Withstands Harsh Environments, Shock and Vibration


The KPA Series Industrial/OEM pressure sensors are a breakthrough that combine several unique features yielding an exceptionally tough and accurate sensor at a low cost. The fitting and pressure sensing diaphragm are precision machined out of a single piece of 17-4 PH stainless steel.

There are no welds or Oring seals which results in an extremely high cycle life. The semiconductor strain gauges are kiln fused to the diaphragm making a highly stable molecular bond. Molecular bonding of the sensing element produces a pressure sensor that will have exceptional long term stability in demanding applications characterized by high pulsations. The KPA series has a 4-20 mA, 2-wire transmitter and 1/4” NPT fitting standard.

Other outputs and fitting options are available in OEM quantities. 316L stainless steel wetted parts are also available in OEM quantities. The KPA also provides significant levels of RFI, EMI and ESD protection making it an excellent choice for industrial and mobile applications.
