ESS319-7 Pressure Sensor
ESS319-7 is the minimal range pressure sensor that can measure the range of 0-7kpa, it’s been designed and manufactured by principle of silicone piezo-resistance and 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.
