Absolute Pressure Transmitter: Working Principle, Zero Calibration, and Applications

Pressure Transmitter /

📖 Introduction An Absolute Pressure Transmitter is a precision instrument designed to measure pressure relative to a perfect vacuum (zero absolute pressure). Unlike gauge pressure transmitters, which reference atmospheric pressure, absolute pressure transmitters use a sealed vacuum as the reference point. This makes them essential in applications where atmospheric pressure variations would otherwise affect accuracy.
