High Accuracy Pressure Sensor PC-302 Series

PC-302 series is high accuracy pressure sensor of ±0.25% at full scale. Gauge or absolute pressure types are available with high temperature option. Dedicated digital panel meter (Lo/Hi 2-stage digital strain gauge meter) is available as display device.

  • Wide Range of Measurement
    Variety of pressure range from 172KPa to 20,684KPa.
  • High Accuracy
    High accuracy pressure detection 0.25% or less with linearity, hysteresis and repeatability all included (100PSIG or more).
  • Wide Temperature Range
    Temperature insensitive design for strain gauge detecting pressure allowing wide temperature range operation. Temperature range expandable by selecting high temperature option.
  • High Corrosion Resistance
    Electrochemical polished SUS316L used for gas contacting area realizing high corrosion resistance against various corrosive medias.
  • Long Lifetime
    Robust construction, pressure detecting diaphragm processed with sensor body.
