The series of pressure sensor is a small size piezo-resistive pressure sensor. The die size is 1x1mm2. When the input voltage is 3vdc the sensor produces mv dc output voltage which is direct proportion of the input pressure. Pressure sensor is the absolute pressure sensor, and we can also offer the differential pressure mode. All the products can be customized according to your requirement.
