The 500G pressure sensor employs a 17-4PH stainless steel mono-block structure, and is designed for high pressure applications. Thanks to the mono-block structure, the sensor has excellent resistance to overload pressure – proof pressure up to 300%fs and burst pressure up to 500%fs. And this structure prevents pressure medium from leakage to the backside of the sensor. In addition, there is no any O-ring needed inside the sensor structure for sealing purpose.
On the pressure diaphragm of the 500G-series pressure sensors, the Wheatstone bridge circuit is built with BCM semiconductor strain gauges via glass-bonding technology, resulting in a creep free behavior of the sensors. Compared to the 664F-series pressure sensors which are based on metal foil strain gauge technology, the 500G-series sensors offer higher output sensitivity (up to 15mV/V).
The 500G is mostly used for pressure transmitter applications for high pressure measurement.
