BLWP040 series pressure sensor is a MEMS pressure sensor with all-silicon structure. The external ambient temperature is -45ºC~ 125ºC, 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.
Characteristics:
• Measuring range: 0~40kPa,-40~0kPa,-40~40kPa
• Type of pressure: gauge pressure
• High sensitivity
• High reliability
• High stability
• Constant voltage source or constant current source
• Low cost
