Capacitance Probe / Sensor Specifications

  • Temperature Rating -200ºF (-130ºC) to 400ºF (205ºC) Probe & Cable. Custom probes to 1200°F (648°C).
  • Accuracy 0.05%, or better, of range when calibrated to a known standard.
  • Probe and Cable Interchangeability Accurate to within ± 0.5% without recalibration.
  • Pressure Rating Standard 200 psig.
  • Cable Length 8 feet; lengths to 50 feet also available.

* Standard capacitance probe range can be significantly increased with amplifier modifications.

** For best linearity, guard thickness should be 2 times or greater the measurement range.

Customized capacitance probes and high temperature sensors are available upon request.
