P1650 Pressure Sensors

Connect directly to any XR440, XR450 or XR5-SE Data Logger; no external power required.

P1650-5 Pressure Sensor with 316L SS wetted parts and 0-5 psig range.

P1650-5 Pressure Sensor (0-5 psig)

For chilled water, hot water, air, gas, oil, steam pressure and many low pressure applications.  See table below for available ranges.

For higher pressure ranges see P1600 Pressure Sensors.

Log up to four (4) pressures with one XR440 or XR450 Data Logger, and up to eight (8) pressures with one XR5-SE Data Logger, for a multi-channel, battery powered pressure recorder requiring no external power.

  • Low Pressure Range: 0 - 5 psi
  • Compound and Vacuum Ranges
  • All 316 Stainless Steel Wetted Parts
  • No O-rings or Seals
  • IP67 Waterproof / Weatherproof Housing

For higher pressure ranges see P1600 Pressure Sensors.

Use any Pressure Scale

P1650 Sensors can be read in any pressure unit (psi, kPa, bar, inches H2O, etc.); see XR440 / XR450 Pressure Converter or XR5 Pressure Converter.

Extension cable

The 10 FT (3 meter) cable on all P1650 Pressure Sensors may be extended up to 100 FT (30 meters) by the user using three conductor 22 gage cable.  In electrically noisy environments we recommend using shielded cable.
