-100Kpa 10Kpa 3.5Mpa OEM Welded Flat Base Piezoresistive Pressure Sensor for liquid pressure system and switch
Brief Introduction
331 High Temperature Pressure Sensor uses radiator to resist 150ºC temperature, the element use highsensitivity 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.
331 High Temperature Pressure Sensor is available pressure ranges from 35Kpa to 10MPa.
Technical parameters
Note: 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.
