Installation and Wiring Guide
Installation Steps
- Confirm that the pipeline or container has been depressurized and close the valve.
- According to the process connection specification, wrap PTFE tape or use a gasket.
- Screw the CPS91D into the installation point and tighten with a wrench, avoiding excessive force that may damage the housing.
- Ensure the cable entry faces downward or sideways to prevent water accumulation.
- Connect the power and signal lines according to the wiring diagram in the manual, paying attention to polarity.
Wiring Precautions
- Use shielded cables, with the shield grounded at one end.
- Avoid parallel routing with power cables to reduce electromagnetic interference.
- Before power-on, check whether the power supply voltage is within the 12~36 VDC range.
Selection and Ordering Information
When selecting, it is necessary to specify the measurement range, process connection, output signal, diaphragm material, and whether a display head is included. Different options correspond to different model codes; please refer to the selection table in the manual.
For special ranges or explosion-proof certification, please confirm with the supplier. Correct selection ensures that CPS91D operates stably for a long time under your working conditions.
Common Problems and Maintenance
Common Problems
- No output signal: Check power polarity, voltage, and whether wiring is loose.
- Output fluctuation: Confirm whether the medium is pulsating, or increase damping setting.
- Zero drift: Recalibrate the zero point and check for overpressure or overtemperature.
Daily Maintenance
- Regularly check appearance and sealing, and clean the housing.
- Perform calibration every 12 months to ensure accuracy.
- Avoid use beyond the rated pressure or temperature range.
