Industrial differential
Pressure Sensor

AV209 industrial pressure sensor is a standard and most popular sensor applied in differential pressure measuring. A high sensitivity silicon pressure chip is employed in the sensor. The housing is filled with oil for pressure transmission. The AV209 sensor is designed for industry application with perfect long term stability.
