#17266–Sensing Technology and Electrical Interface Selection for Areas with High EMI/RFI Intensity

The foundation of any development, improvement, or progress in the modern world requires a baseline measurement for comparison to future results. This baseline is established through initial measurement of the current state of a technology, and subsequent modifications must also be measured to determine progress (or lack thereof). Sensing technologies are essential in establishing these baselines and determining continuous growth. As such, they will continue to play a crucial role in the development cycle.

Selecting the appropriate sensing technology for a measurement task can be challenging due to the multitude of options available. This selection process becomes even more complex when dealing with EMI/RFI (Electromagnetic Interference/Radio Frequency Interference), which can alter, disrupt, or interfere with electrical signals. Digital technologies possess safeguards against EMI/RFI, but analog signals remain vulnerable. The rise in electric devices and vehicles has led to increased EMI risks in environments with high switching and induction currents. In analog measurements, real-time signal accuracy verification is not possible, making EMI/RFI an even greater concern.

Here, we examine the susceptibility of various prominent sensing technologies and electrical interfaces to EMI/RFI. It is crucial to note that the effects of EMI/RFI depend heavily on factors such as installation, cable length, DAQ system specifics. We will compare the performance of different vibration sensor technologies under similar conditions.
