Installation and Commissioning Steps
Correct installation is key to ensuring the measurement accuracy of the PMC51. Please follow the steps below and refer to the detailed illustrations in the Chinese manual.
- Confirm that the pipeline has no pressure, close the valve, and drain the medium.
- Install the transmitter at the measurement point using a suitable sealing gasket.
- Tighten the process connection, with torque not exceeding the value specified in the manual.
- Connect the power and signal wires, paying attention to correct polarity.
- After power-on, use a HART communicator to perform zero calibration.
- Check whether the output current corresponds to the pressure value.
Selection Precautions
When selecting, consider medium compatibility, pressure range, and environmental conditions. Be sure to refer to the selection table in the PMC51 Chinese manual.
- Corrosive media: choose Hastelloy or tantalum diaphragm.
- High-temperature media: add a condensation coil or capillary.
- Explosion-proof occasions: choose intrinsically safe or flameproof type.
- Sanitary industry: choose clamp connection and polished wetted parts.
Common Problems and Maintenance
Regular maintenance can extend the service life of the PMC51. If abnormal output occurs, first check the power supply and wiring.
Troubleshooting
- No output: check whether the power supply voltage is within 12~45VDC.
- Output too high/too low: recalibrate zero and span.
- Display fluctuation: check damping settings and medium pulsation.
