Product Description

Joint type Welded Flush Diaphragm Pressure Sensor for liquid, gas pressure measurement

Brief Introduction
The joint type welded Diaphragm Pressure Sensor, with narrow range and joint type connection, is the simplified version of 322, it uses a high-sensitivity piezoresistive silicon die as sensing component, which is protected against ambient influences by SS316 housing sealed with a concentrically corrugated diaphragm. Inside the housing, the filled silicone oil assures the measured pressure can be transmitted onto silicon die and then transform the pressure to electric signal.
323 is available pressure ranges from -100Kpa to 10MPa.
