Uncompensated Pressure Sensor

Merit Sensor RSH Series

  • โ€‹Uncompensated pressure sensor with MEMS-die-on-pressure-port design.
  • Compatible with wet and harsh media.
  • Suitable for broad temperature and pressure ranges.
  • Pressure range 0 to 500 psi (absolute or gauge).
  • Operating temperature range -40ยฐC to 150ยฐC
  • Compliant

The RSH Series is compatible with wet and harsh media due to its MEMS-die-on-pressure-port design. This design isolates the media to the backside of the MEMS silicon die and inside of the Kovar or ceramic pressure port. The RSH Series is a great pressure sensor for broad temperature and pressure ranges. Better yet, it is available at a lower cost than fully compensated pressure-sensor packages, making it ideal for customers who know how or prefer to do their own compensation.

  • Pressure Range: 0 to 500 psi
  • Temperature Range:ย -40 to 150 ยฐC
  • Pressure Type: Absolute or gauge (backside pressure for both)
  • Media:ย Air, gases, and liquids
    (to be determined on an application-by-application basis with Merit Sensorโ€™s engineering team)
  • Shipping: Tape and reel
  • Flexibility:ย Range of pressure, size of pressure port, and pressure type
  • Customizations are available upon request

Typical applications for the Merit SensorTM RSH series include:

  • Industrial:ย Process control, water pressure, and flow management
  • Medical:ย Inflation
