Product Description
CPG series pressure sensor is an all-silicon MEMS pressure sensor, the external ambient temperature is -40°C~125°C, and the pressure can be -100kPa~0kPa··· Accurate measurement of 700kPa with a good linear relationship with the output voltage. This product is specially designed for low-cost and long-term high reliability pressure measurement, and can be widely used in home appliances, medical, sports and industrial pressure measurement fields.
This series of pressure sensors are available in standard SOP and DIP packages, which are easy for users to use, with good linearity, repeatability and stability, as well as high sensitivity, which is convenient for users to use op amps or integrated circuits to debug and compensate for output and temperature drift.
