Pressure Sensor HySense® PR 509The HySense® PR 509 with its high-grade steel membrane and stainless steel housing, is an extensively proven pressure sensor for mobile applications. It is available with Hydrotechnik Intelligent Sensor Detection System (ISDS), the automatic sensor detection system. Designed for use with Hydrotechnik data recorders in the MH20xx series, it is a 4-20mA output sensor with integrated 2.5m cable. 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.
It is available in several pressure ranges from 0 to 600 bar.
