The Define Instruments PRO-PRC panel meter can average inputs across 2, 3, or 4 input channels and use the averaged value for a display source or setpoint activation. It can be used on its own or along with another instrument, such as a transmitter.

The unit accepts key-in calibration without the need of an input signal. You can configure up to 4 setpoints, depending on the number of relays you select. Your settings remain secure with PIN protection; the input calibration and setpoint functions have independent codes so you can give access to one and not the other. It also features an option to log and store your data in the controller's internal memory, where it can be printed or accessed with Excel-compatible programs for easy analysis.

The PRO-PRC uses input signal averaging to reduce noise and ensure stable measurements. If the change in input exceeds the averaging window value it will not average, ensuring fast response when there are large differences between readings. If your input signal contains large noise spikes you can increase the size of the averaging window to ensure that these are still averaged as well.
