The following are four basic things you can do to reduce EMI and RFI on measurements:
- Use a shorter cable, if
possible. For more details, see
Use shorter cable lengths.
Note: The leads on the sensor cables, as delivered, are specially prepared for ease of installation. Before attempting to cut the cables, be aware that cutting cables is associated with significant additional rework to correctly prepare the sensor for installation.
- Run the cable through a conductive conduit, grounded at both ends. For more details, see Use a conductive conduit.
- Install ferrites on the cable. For more details, see Install ferrites.
- Avoid running the cable such that it matches the polarization of expected interference sources. For more details, see Reduce polarized interference.
Note: The best approach in mitigating interference also depends on the application and on local installation codes.
