a flush diaphragm facing the pressure media, able to measure pressures of viscous liquids

small size Pressure Sensors Model :101B-a15G

 

101B-a15G OEM pressure sensors are manufactured from BCM piezoresistive silicon dies. The sensors are designed with CAD, the performance is simulated and the sensor prototype is fully tested before batch production. Serious quality control and dedicated calibration processes guarantee the specifications of these OEM pressure sensors in mass production and the higher production eligible rate.

101B-a15G OEM pressure sensors possess a flush diaphragm facing the pressure media, able to measure pressures of viscous liquids, the diaphragm form a chamber, in which oil is filled to isolate the sensing element and transfer pressure. This isolation enables the sensor to measure the pressures of corrosive fluids as well as electro conductive liquids. 

The model of 101B-a15G has a wide pressure range of 0~35 to 0~350 bar, and a high accuracy up to 0.25%fso, although the compensation temperature range is 0~70°C, the sensor can still work in the temperature range of -45°C ~ +125°C. another advantage is constant current or constant voltage are both available as excitation power supply, this making 101B-a15G has a wide application areas. 

Model 101B-a15G OEM pressure sensors are designed for easy installation with O-rings as sealing method, the sensor has a diameter of 15 mm, the suffix G stands for general pressure applications.

All OEM pressure sensors are delivered with an individual certificate to aid their further application.
