PR 190 Data Sheet 

Pressure Sensor HySense® PR 190

Pressure sensor HySense® PR 190 The HySense® PR 190 with its high-grade steel membrane, is a pressure sensor for mobile applications. Optionally, it is available with Hydrotechnik ISDS, the automatic sensor detection system. The HySense® PR 140 has a protection type of IP 68 K. It has an open ended, 4 wires connection with connection cable of 1.5 meter.

They operate on a piezoresistive cell principle. Piezoresistive materials change resistance to flow of a current when compressed or strained. A "Wheatstone bridge" runs a small current through the cell and measures the returned current to determine the current change. This is then translated as a pressure change.
