PMP51 Selection Points
1. Measuring medium and range
Select wetted materials based on medium corrosiveness, such as 316L stainless steel, Hastelloy, or tantalum. The range should cover the maximum working pressure with a margin.
2. Process connection and sealing
Common connections: G1/2, NPT1/2, DN25 flange, etc. The sealing method must match the medium temperature and pressure.
3. Electrical connection and communication
Confirm the supply voltage and communication protocol. HART is suitable for remote configuration, and PROFIBUS PA is suitable for bus systems.
PMP51 Installation and Commissioning Steps
- Installation position: Avoid vibration, heat sources, and corrosive environments, and ensure the process connection is aligned.
- Electrical wiring: Connect the power and signal lines according to the wiring diagram in the manual, paying attention to polarity.
- Configuration settings: Set the range, damping, and units via local buttons or a HART handheld terminal.
- Zero calibration: Perform zero adjustment under no pressure.
- Verify output: Check the correspondence between the 4-20mA output and pressure.
