SENSOR Description The model 101B(a19D) is a low-profile compensated differential pressure sensor, based on the BCM SE103 piezoresistive silicon sensor die. The sensing element is packaged in a 316L SS (stainless steel) housing where silicone oil is filled. Through the filling oil, measured pressure can be transferred from the 316L SS diaphragm to the sensing element. The 101B(a19D) which can be sealed by an O-ring features wetted parts with a diameter of 19mm. The 101B(a19D) is designed for differential pressure measurement from 0~0.1bar to 0~20bar with accuracy up to 0.5%fs (full scale). Owing to the flush diaphragm, the sensor is enabled to measure viscous fluids or fluids with particles, and it is also compatible with corrosive media. Features • differential ranges: 0.1bar, ..., 20bar • accuracy up to 0.5%fs • temperature compensation by laser trimming • O-ring sealing method • isolated construction, suitable for various fluid media • constant current or constant voltage excitation Physical Properties • diaphragm: 316L SS • wetted parts: 316L SS • O-rings: fluorine rubber • filling fluid: silicon oil • laser trim board: ceramic • weight: ~ 46g Applications • process control systems • hydraulic systems • liquid level control • biomedical instruments • flow measurement • OEM equipment Reference Specifications • media temperature: 25 ±1 °C • ambient temperature: 25 ±1 °C • vibration: 0.1 g (1m/s/s) max • relative humidity: 50% ±10% • ambient pressure: 0.86~1.06 bar • excitation source: 1.5 ±0.0015 mA dc Environmental Conditions • position effect: s£2%fs of Zero shift for 90o tilt in any direction. Higher the measuring range of the sensor is, lower the Zero shift will be. • vibration effect: no influence until 10 g (RMS), 20~2000 Hz • shock: 100 g, for 10 millisecond • life time: 100 million cycles Industriepark Zone 4, Brechtsebaan 2 B-2900 Schoten - Antwerpen, BELGIUM website: www.bcmsensor.com email: sales@bcms
