Selection Points
Select the appropriate 8H1B model according to actual working conditions. Refer to the following dimensions.
- Measurement Medium: Gas, liquid, or steam, which affects the choice of wetted material.
- Process Connection: Thread, flange, or clamp, which must match the on-site pipeline.
- Output Signal: Choose 4-20mA, HART, or RS485 according to the control system interface.
- Explosion-proof Requirements: For hazardous areas, choose intrinsically safe or flameproof type.
- Display Method: Local LCD or remote communication.
Installation and Commissioning Steps
Correct installation and commissioning are key to ensuring the long-term stable operation of the 8H1B.
- Confirm that the installation location has no strong vibration or corrosive gases and reserve maintenance space.
- Tighten the process connection according to the torque requirements in the manual to avoid leakage.
- Connect the power and signal lines according to the wiring diagram, paying attention to polarity and shield grounding.
- After power-on, check whether the display is normal and there are no alarm codes.
- Use a hand-held communicator or host computer to calibrate zero and span.
- Record the commissioning parameters and complete commissioning.
Common Problems and Maintenance
Regular maintenance can extend the service life of the 8H1B. The following are common problems and handling suggestions.
- No Output Signal: Check the power supply, wiring polarity, and fuse.
- Large Measurement Deviation: Recalibrate zero and span, and check whether the sensor is blocked.
- Communication Interruption: Confirm that the address, baud rate, and terminal resistance match.
- Abnormal Display: Check whether the supply voltage and ambient temperature exceed limits.
It is recommended to perform a comprehensive calibration every 12 months and keep records.
