Installation and Commissioning Steps
Correct installation is the prerequisite for ensuring measurement accuracy. Please follow the steps below.
- Confirm that the pipeline has no pressure and close the shut-off valve.
- Install the transmitter at the measurement point using a suitable gasket.
- Connect the electrical wiring, paying attention to power supply polarity.
- After power-on, use a HART communicator to perform zero calibration.
- Slowly open the shut-off valve and check whether the output is normal.
Wiring Precautions
- Use shielded cables, with the shield grounded at one end.
- Avoid laying cables parallel to power cables.
- In explosion-proof situations, relevant regulations must be followed.
Selection and Maintenance Key Points
When selecting, comprehensively consider the range, process connection, medium compatibility, and explosion-proof requirements.
- Range selection: It is recommended that the working pressure be 60%~80% of the range.
- Process connection: Choose thread or flange according to the pipeline interface.
- Diaphragm material: For corrosive media, choose Hastelloy or tantalum diaphragms.
Regularly check the transmitter appearance and zero point. It is recommended to calibrate once every 12 months.
Frequently Asked Questions
What should I do if the output signal is unstable?
