The Define Instruments PRO-RTD panel meter accepts direct sensor input from RTD 385, 392, and CU10 temperature probes. It can average inputs across 2, 3, or 4 temperature channels and use the averaged value for a display source, as a data source for analog output, serial output, setpoint control, or the peak and valley values. The PRO-RTD 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-RTD 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. 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.
