Installation and Wiring Steps
Correct installation and wiring are prerequisites for ensuring the long-term stable operation of the CPS42D. Please operate according to the following steps:
- Confirm that the pressure in the pipeline has been released, and close the shut-off valve.
- Wrap PTFE tape or apply sealant on the threads, and screw the transmitter into the mounting base.
- Tighten with a wrench, avoiding excessive force that may damage the housing.
- Connect the power and signal wires according to the wiring diagram in the Chinese manual, paying attention to polarity.
- After power-on, check whether the output is normal, and perform zero calibration if necessary.
Wiring Definition (Taking 4～20mA Two-Wire System as an Example)
- Red wire: Power supply positive pole (+24VDC)
- Black wire: Signal output/power supply negative pole
- Yellow-green wire: Shielded grounding
Selection and Usage Precautions
During selection, key attention should be paid to pressure range, output signal, process connection, and medium compatibility. The following points can help you avoid common mistakes:
- The range should be selected so that the working pressure is between 60%～80% of full scale to extend service life.
- For corrosive media, choose 316L stainless steel or Hastelloy diaphragms.
- In vibrating occasions, it is recommended to install a damping device or choose an anti-vibration type.
- For outdoor installation, a protective cover should be added to avoid direct sunlight and rainwater immersion.
Common Questions and Maintenance
What should be done if the output signal is abnormal?
- Check whether the power supply voltage is within the range of 12～36VDC.
- Check whether the wiring is loose or the polarity is reversed.
- Confirm whether the actual pressure in the pipeline exceeds the range.
How to clean and maintain it?
- Regularly wipe the housing with a soft cloth, and avoid using corrosive solvents.
- Check the sealing ring every six months, and replace it in time if aged.
- When not in use for a long time, store it in a dry environment at room temperature.
