SenseDisc Absolute Pressure

Absolute Pressure Sensor is used to measure absolute pressure of gas. The sensor touches gas via the hose at front side. Pressure difference between hose and sealed vacuum cavity inside the sensor is formed. That pressure difference is converted to voltage signal. The output voltage is direct proportional to absolute pressure.
