Seametrics PS9800 Pressure and Optional Temperature Sensor with 4-20mA Interface

Feature

  • Pressure (temperature optional)
  • ± 0.1% FSO accuracy
  • Lower power (9-30Vdc)
  • Small diameter—0.75” (1.9cm)
  • 1/4” NPT end cone adapter option (300psi max.)

The Seametrics PS9800 pressure transmitters are rugged and accurate with great noise immunity, transient protection, and thermal performance. These pressure sensors have been designed to provide trouble-free submersible operation in liquid environments.

The pressure is measured with an extremely rugged and stable piezo-electric, media isolated pressure element and calibrated with well-established calibration procedures and NIST traceable equipment.

The PS9800 sensors are thermally compensated, making them great where water temperatures vary, as they are thermally stable (2% over 50 degrees standard). These industry-standard, 2-wire, 4-20mA devices offer reverse polarity protection, under- and over-current limitation, and built-in transient protection.

Application

  • Pump and slug tests
  • River, stream, reservoir gauging
  • Stormwater runoff monitoring
  • Wetland Monitoring
  • Well, tank, tidal levels
  • Flow monitoring
  • Water resource management
  • Landfill leachate levels
  • Control applications
