Geotech Pressure Transducers

Geotech's submersible pressure transducers are designed for ruggedness and long life to meet the demanding environments encountered in liquid level measurement and control.

  • High static accuracy and repeatability
  • 100% computer tested and calibrated
  • Temperature compensated measurement
  • Signal outputs of 4-20 mA, 1-5 Volt output, and Modbus RS485
  • User specified pressure ranges from...
    – 100-1500 psi (7-100 bar) Sealed Gauge
    – 15-1500 psi (1-100 bar) Absolute
  • All wetted materials are #316 stainless steel
  • Designed to be intrinsically safe
  • Cable is premium quality, double-shielded, yellow polyurethane jacketed Tefzel®,
    or blue modified PVC blend
  • Sensor has ¼" NPT process fitting with protective cap
  • Optional surge suppressor for lightning protection
