To install the FW MURPHY PXT-K Enovation Controls Pressure Transmitter, please follow the instructions below:
1. Before installation, visually inspect the product for any damage during shipping.
2. Disconnect all electrical power to the machine and follow the lock-out/tag-out safety procedures of your company to ensure the machine cannot operate during installation.
3. Read and follow all safety warnings and installation instructions provided by the machine manufacturer.
4. The PXT-K Series pressure transmitters are state-of-the-art instruments that provide 4-20 mA outputs. They are designed to be rugged and resistant to EMI/RFI interference.
5. The operating range for the PXT-K is 8-30 VDC. Refer to the operating range chart in the manual to determine the minimum supply voltage required for your specific load resistance.
6. Take precautions to avoid pulsating pressure variations that can damage the pressure transmitter. Apply pressure slowly and open/close valves gradually. Consider installing a surge chamber or pressure snubber to dampen surges and hammers.
7. The PXT-K and PXT-KM pressure transmitters have different pressure ranges. Refer to the pressure range table in the manual to select the appropriate model for your application.
8. The pressure transmitter can be mounted on any axis as long as it is perpendicular to the flow being monitored. Avoid excessive vibration during installation.
9. Apply Teflon tape or sealant to the pressure-fitting threads before installing. Tighten the pressure fitting using a wrench on the hex wrench flats, avoiding the use of a pipe wrench on the housing.
10. Take precautions to minimize noise susceptibility. Avoid running the transmitter cabling in a conduit with high voltage AC power cables or near inductive equipment. Shielded cable is recommended.
11. The PXT-K Series pressure transmitters are not constructed to be isolated, and the shield/drain should not be grounded in the panel. Ground the shield/drain only on the panel end.
12. Refer to the dimensions, connections, and accuracy information in the manual for further details on the physical dimensions and accuracy tolerances of the pressure transmitter.
Please note that this is a general overview of the installation process. For specific installation instructions and further details, refer to the FW MURPHY PXT-K Enovation Controls Pressure Transmitters Instruction Manual.
