ESS331 High Temperature Pressure Sensor
ESS331 High Temperature Pressure Sensor uses radiator to resist 150℃ temperature, the element use 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.
ESS331 High Temperature Pressure Sensor is available pressure ranges from 35Kpa to 10MPa.
