High performance pressure sensors

The sensors are ideally suited for measuring pressures in physical models.

If you would like to measure

  • impact pressures on structures, choose high pressure sensors mounted with a flush diaphragm.
  • water depth and wave pressure under rubble mounds or pressure in pipes and other vessels, high pressure sensors threaded with a protective nose cone are better fit for these purposes.

We offer high pressure sensors with flush diaphragm or protective nose cone for 2m, 5m and 10m water gauges.

Product features
  • Covers depth and impact measurements
  • 17mm diameter sensor
  • Digital display
  • 0-5V output signal
HRIA-1036, HRIA-1037, HRIA-1038, HRIA-1039, HRIA-1040, HRIA-1041
Diaphragm and cables 

The all welded diaphragm and body are manufactured from 316 stainless steel.

The sensors are supplied with a 10m length of vented cable, which has an internal vent tube and strainer wire. Alternative cable lengths can be ordered on request.

A display unit with a digital panel meter for easy readings
Digital display unit option

You can choose to purchase your pressure sensors equipped with a digital display unit, which shows pressure in a range of parameters.

The digital display unit contains a digital panel meter, which has a 0-10V output and a serial RS 422/485 connection. A separate power supply unit, which allows the instrument to be used with either 110V AC or 220V AC supplies.

It is supplied with a case and 0 - 5V output.
