- Strong Anti-interference: Suitable for electromagnetically complex environments.
- Wide Temperature Compensation: Built-in temperature sensor automatically corrects temperature drift.
- Protection Rating: IP65/IP67, suitable for outdoor and humid occasions.
Selection Guide
Correct selection is the prerequisite for ensuring that the CPF81 meets on-site requirements. Please confirm according to the following steps.
- Confirm the measured medium and range to avoid overpressure or small-signal use.
- Select the output signal according to the control system interface (e.g., 4~20 mA, HART, etc.).
- Check the process connection thread and sealing material to ensure compatibility with the medium.
- Confirm the ambient temperature, protection rating, and explosion-proof requirements (if any).
- Refer to the selection table in the manual to determine the complete model code.
Installation and Commissioning Steps
Mechanical Installation
- The installation location should be convenient for observation and wiring, avoiding strong vibration sources.
- Use appropriate gaskets and tighten the process connection according to the torque requirements.
- For liquid measurement, it is recommended that the pressure tap be located on the side or bottom of the pipe.
Electrical Connection and Commissioning
- Disconnect the power supply and connect the power and signal lines according to the terminal diagram in the manual.
- Check the polarity and power on after confirming it is correct.
- Use a hand-held communicator or HART communicator to calibrate the zero point and range.
- Observe whether the output current corresponds to the pressure value, and fine-tune if necessary.
- Record the commissioning parameters and lock the settings to prevent accidental changes.
Common Problems and Maintenance
- No Output: Check the power supply, wiring polarity, and fuse.
- Large Output Deviation: Recalibrate the zero point and range, and check whether the impulse pipe is blocked.
- Display Fluctuation: Confirm the damping setting and eliminate medium pulsation or electromagnetic interference.
- Regular Maintenance: It is recommended to check the sealing and wiring every six months and calibrate once a year.
