BLWP21000 board mount pressure sensor
Details
DESCRIPTION ：
BLWP21000 is a high-precision MEMS pressure sensor. When the ambient temperature is -45℃ ~ 125℃, it can accurately measure the pressure from 0 to 1000kPa. The pressure and output voltage show a good linear relationship. The pressure sensor uses open loop detection, SOP6 package
CHARACTERISTICS ：
- Range: 0~1000kPa
- High sensitivity
- High reliability
- High stability
- Constant voltage source or constant current source supply
- Small size
- Low cost
