High accuracy resonant pressure sensor

The RPS/DPS 8200/8300 moves the exciting new TERPS technology into harsh media environments. TERPS is a resonant silicon pressure sensor technology platform that provides an order of magnitude greater accuracy and stability than current pressure measurement technologies available.

The new TERPS technology also extends the pressure range capability to high pressures and by incorporating true pressure media isolation greatly improves its suitability for use in harsh environments


Product Overview
  • High Precision, ±0.01% FS over compensated temperature range
  • High Stability, ±100 ppm FS/year
  • Wide temperature range, -40°C to +125°C (-40°F to 257°F)
  • Media isolated construction, suitable for use in harsh environments
  • Multiple Output configurations, RS-232, RS-485, Frequency & Diode (TTL)
  • Selection of pressure & electrical connections to suit specific requirements

Pressure Ranges

  • 0 to 2 bar (0 to 30 psi) absolute
  • 0 to 7 bar (0 to 100 psi) absolute
  • 0 to 14 bar (0 to 200 psi) absolute
  • 0 to 20 bar (0 to 300 psi) absolute
  • 0 to 35 bar (0 to 500 psi) absolute
  • 0 to 70 bar (0 to 1000 psi) absolute
  • (Values in psi are approximate.)
  • The lowest calibrated pressure is 35 mbar absolute.

1.5X FS

Sensor Failure Pressure
2.0X FS

Pressure Containment

  • Ranges to 7 bar, (100 psi), 70 bar (1,000 psi)
  • Ranges to 70 bar (1,000 psi), 200 bar (3,000 psi)

There are two levels of performance specification: standard and Improved.

Specifications include combined effects of non-linearity, hysteresis, repeatability and temperature errors over the compensated temperature range, and over the pressure range 35 mbar to the full scale pressure.
