BLWP3XXX-M absolute pressure sensor
DETAILS
DESCRIPTION ：
The all-silicon MEMS absolute pressure sensor series BLWP3XXX-M can accurately measure the external ambient temperature of -45℃ ~ 125℃ and the absolute pressure in multiple ranges, and has a good linear relationship with the output voltage. This series of pressure sensor has the advantages of small size and high reliability.
CHARACTERISTICS ：
1. Range: 0~ 110,0 ~ 300,0 ~ 500,0 ~ 700,0 ~ 1000,0 ~1700kPa,(absolute pressure)
2. All silicon structure
3. High stability and reliability
4. Nonlinearity better than 0.1%
5. With 3 times the benchmark range overload capacity
6. It has high repeatability and consistency
7. Full-scale output voltage 50mV ~ 90mV (typical value for 5V power supply)
