Installation and Commissioning Points
Correct installation and commissioning are key to ensuring long-term stable operation of the PMP23.
Installation Steps
- Confirm that the process connection specifications match the pipeline interface.
- Use appropriate gaskets during installation to avoid overtightening and damaging the diaphragm.
- For liquid measurement, the transmitter should be installed on the side or below the pipeline to prevent bubble accumulation.
- For gas measurement, the transmitter should be installed above the pipeline to prevent condensate accumulation.
- Perform electrical connections according to the wiring diagram in the manual, paying attention to power polarity and shielded grounding.
Commissioning Precautions
- Check whether the power supply voltage is within the allowable range before energizing.
- Use a HART communicator or configuration software for range and zero calibration.
- Avoid long-term operation under over-range pressure.
- Regularly check sealing performance and waterproofing of electrical interfaces.
Selection Recommendations
When selecting, comprehensively consider the measuring medium, pressure range, output signal, and environmental conditions. It is recommended to first confirm whether the process connection and diaphragm material are compatible with the medium.
- Corrosive media: choose Hastelloy or tantalum diaphragm.
- High-precision applications: choose models with higher accuracy grades.
- Explosion-proof areas: confirm that the corresponding explosion-proof certification is available.
- Remote transmission requirements: choose HART or bus output.
Frequently Asked Questions (FAQ)
Where can I download the PMP23 Chinese manual?
The PDF download link is provided at the beginning of this article, or you can contact the supplier for the latest version.
Can PMP23 measure negative pressure?
Some ranges support negative pressure measurement; please refer to the range table in the manual for details.
How can I determine whether PMP23 needs calibration?
If the output signal deviates from the process parameter beyond the allowable error, or the regular maintenance cycle is reached, calibration is recommended.
