EMI (Electromagnetic Interference)
Identify the source of the interference. The most common sources of electromagnetic interference are listed in the Installation Considerations section. To eliminate EMI try the following methods:
1.Move the sensor or the sensor cable away from the EMI source or move the source of the EMI away from the sensor or the cable.
2.Connect the Sensor’s GND terminal to true earth ground (if this isn’t feasible use the main system unit’s GND terminal).
There are many methods for reducing interference. Which solution is best for you depends on your situation. If you require further assistance call Niles Technical Support at
