BLWP040 Pressure Sensor
Details
BLWP040 series pressure sensor is a MEMS pressure sensor with all-silicon structure. The external ambient temperature is -45℃~ 125℃, which can achieve accurate pressure measurement and show a good linear relationship with the output voltage. This series of pressure sensor adopts open loop detection, SOP6, DIP6 package, broaden the product application way.
