Pressure sensor compact size piezoresistive 0-10bar-1000bar dia. 12.6mm
The compact Size Piezoresistive Pressure Sensor is, a newly developed sensor that benefits 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.
Its workable pressure range from 10bar to 100 bar.
Technical parameters
Remarks: Range -100KPa~100MPa; *The typical value of 0~10KPa and 0~20KPa's zero; temperature drift and sensitivity temperature drift is 0.4%FS@25ºC, max value is 1.6%FS@25ºC
Standard range
Notes: G for Gauge pressure; A for Absolute pressure; D for Differential pressure; S for Sealed gauge.
