Accelerometer EMI and RFI considerations
6.1.5

Summary

To maximize immunity to EMI/RFI, consider the following when planning the installation of
the CSI 9420 and its accelerometers:
Required
• Use ferrites to attenuate interference that couples into the accelerometer cable.
• Ensure the installation conforms with all local codes and regulations.
Best practice
• Use a shorter cable, if possible.
• Consider running accelerometer cables in conductive conduit, grounded on both ends.
• Avoid vertical cable runs because this geometry increases susceptibility to vertically polarized
causes of interference.
