PMC11 Core Technical Parameters
The following table lists the main technical parameters of the PMC11 pressure transmitter for selection reference.
| Parameter item | Specification description |
|---|---|
| Measuring range | 0～0.1 MPa to 0～60 MPa |
| Output signal | 4～20 mA / HART |
| Accuracy class | ±0.5% FS |
| Power supply | 12～36 VDC |
| Process connection | G1/2, 1/2 NPT, etc. |
| Protection class | IP65 / IP67 |
| Medium temperature | -40～85 ℃ |
PMC11 Selection Points
1. Determine the measuring range
Select an appropriate range according to the actual working pressure. It is recommended that the normal working pressure be between 60%～80% of the range to balance accuracy and overload capacity.
2. Choose the output signal
If remote configuration and diagnostics are required, give priority to HART communication; if only analog transmission is needed, 4～20 mA is sufficient.
3. Process connection and material
Choose G1/2 or 1/2 NPT according to the pipeline interface. For corrosive media, stainless steel or Hastelloy diaphragms should be used.
PMC11 Installation and Commissioning Steps
- Installation position: Avoid vibration, high temperature, and strong electromagnetic interference. Vertical installation is recommended.
- Connect the pipeline: Use appropriate seals and tighten the process connection according to the torque requirements.
- Electrical wiring: Connect the power and signal lines according to the wiring diagram in the manual, and pay attention to polarity.
- Power-on inspection: After power-on, observe whether the output current is normal. When there is no pressure, the output should be 4 mA.
- Zero calibration: Perform zero adjustment under no pressure to ensure the display is 0.
- Range setting: Set the upper and lower limits via the HART communicator or buttons.
Common Faults and Handling
| Fault phenomenon | Possible cause | Handling method |
|---|---|---|
| No output signal | Power supply reversed or open circuit | Check wiring and supply voltage |
| Output too high/too low | Zero drift or blockage | Clean the impulse pipe and recalibrate |
| Display fluctuates greatly | Medium pulsation or interference | Add damping or shielded cable |
| Communication failure | Missing HART resistor | Connect a 250 Ω resistor in series in the loop |
Maintenance and Precautions
- Regularly check the process connection for leaks.
- Avoid over-range use to prevent sensor damage.
- In explosion-proof occasions, intrinsic safety or flameproof regulations must be followed.
- For long-term shutdown, disconnect power and store properly.
