ESS323 Welded Joint Type Pressure Sensor

ESS323 Welded Joint Type Pressure Sensor, with narrow range and joint type connection, is the simplified version of ESS322, 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.

ESS323 is available pressure ranges from -100Kpa to 10MPa.
