The Thermocouple Converter is a 1-channel isolated barrier designed for reliable temperature measurement in hazardous environments. It features a thermocouple input and provides a 4 mA to 20 mA output, ensuring compatibility with various industrial control systems.
The Thermocouple Converter is part of a specialized family of intrinsic safety barriers that facilitate safe temperature monitoring in potentially explosive atmospheres. These devices are engineered to ensure that electrical signals are transmitted without compromising safety, making them ideal for use in industries such as oil and gas, chemical processing, and other sectors requiring stringent safety compliance.
Equipped with internal cold junction compensation, the converter ensures accurate temperature readings by compensating for variations in temperature at the connection points. The device also incorporates sensor breakage detection, providing an additional layer of reliability. Its DIP switch selectable ranges allow for flexible configuration to meet various application requirements, enhancing versatility in temperature measurement tasks.
