Air / Gas Differential Pressure Transmitters - DPTA Series:

  • The ProSense differential pressure transmitter DPTA Series is precision engineered for accurate low differential pressure measurement of air and non-condensing, non-corrosive gases in industrial, commercial and OEM applications.
  • Highly reliable, ultra-thin single silicon crystal diaphragm capacitive differential sensor provides inherent repeatability and stability with no glues or other organics to contribute to drift or mechanical degradation over time.
  • These differential pressure transmitters are available in ranges from 0.1 to 25 inches (2.5mm to 635mm) of water column to measure positive, negative, and bi-directional pressures with the ability to withstand 15 psi overpressure without damage or calibration shift.
  • The easily accessible brass barbed pressure ports, removable terminal blocks, and rugged ABS housing capable of 35mm DIN rail or panel mounting make installation quick and easy.
  • These air differential pressure sensors are also sometimes referred to as: 
    bidirectional pressure sensors/transducers, capacitive pressure sensors/transducers, DP sensors, DP transmitters, or DP transducers.
