Correct pressure sensor installation is essential for accurate measurement and long service life. For pressure sensor mounting, select a location with stable temperature, low vibration, and easy access. Mount the sensor vertically or as specified, with the pressure port downward for gas or upward for liquid to prevent trapped air or sediment. Use a proper sealing method such as an O-ring, PTFE tape, or metal gasket. Avoid over-tightening; follow the manufacturer's torque value. For differential pressure sensors, connect high and low pressure ports to the correct taps and keep impulse lines equal in length. Install a shut-off valve and, if needed, a drain valve for maintenance. When piping, avoid sharp bends and ensure the impulse line slopes to prevent condensation. For high-temperature media, use a cooling coil or siphon tube. For corrosive media, add a chemical seal or diaphragm. Sensor wiring should match the sensor output: 2-wire, 3-wire, or 4-wire. Use shielded cable, ground the shield at one end, and keep signal cables away from power lines. Check the supply voltage and polarity before powering on. After installation, perform a leak test and zero calibration. If the sensor has an adjustable range, set the lower and upper limits. Finally, document the installation and verify readings with a known pressure source. Proper installation reduces drift, vibration errors, and blockage, ensuring reliable performance in industrial systems. Always follow local codes and the sensor datasheet.
