ESS312 Compact Size Pressure Sensor
ESS312 Compact Size Pressure Sensor is a new range of sensor that benefit from smaller capsule dimensions (Φ12.6mm) and crevice free diaphragms. 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.
ESS312 is available the ranges from 200Kpa to 100Mpa.
