A2 – Non-Linear Temperature Indicator

Overview
The A2 Non-Linear Temperature Indicator is designed for applications where sensor outputs are inherently non-linear. It provides accurate Temperature measurement for a wide range of thermocouples and RTDs, with built-in cold junction compensation and advanced sensor break diagnostics. This model is ideal for environments where precise interpretation of non-linear sensor behavior is essential.

Working Principle
This indicator accepts inputs from thermocouples (J, K, R, S, B) and RTDs. It incorporates a specialized algorithm to linearize non-linear sensor signals and displays the processed Temperature values on a bright 3½ digit red LED display. In the event of a sensor break, a distinctive fault indication appears, ensuring quick detection and troubleshooting.
