Arc Sensors - Signal Averaging

Certain applications may appear noisy to an Arc sensor and influence process control. One way to improve signal stability is to adjust the moving average setting using ArcAir software.

What is the Moving Average?

Since Arc sensors are digital, they are constantly sampling the primary measurement value. Moving average allows each measurement to be averaged over a number of samples. The result of this averaging is a smoother output. Increasing the moving average will slow down the response of the sensor. This can be seen in the graphs below.
