TT – Temperature Transmitter

Overview
The Temperature Transmitter (TT) is a high-performance, dual-channel device designed to accurately convert a wide range of Temperature sensor inputs into isolated analog current or voltage signals. Engineered for industrial applications, it ensures reliable, noise-resistant signal transmission for precise Temperature monitoring and control. Its compact DIN-rail mount design makes it easy to integrate into control panels and automation systems.

Working Principle
The Temperature transmitter accepts input signals from thermocouples, RTDs (like PT100 or Cu50), millivolt sources, or linear voltage/current inputs. It processes the signal using high-performance circuitry and generates two isolated analog outputs—either 4–20 mA or user-defined voltage signals. Automatic cold junction compensation and advanced digital adjustment ensure stability, accuracy, and immunity from external interference.
