This Burnham Commercial Thermocouple is a vital component designed for temperature sensing and control in various heating systems. With a length of 30 inches, it provides ample reach for installation in larger systems. The thermocouple operates at a voltage of 24 volts, making it compatible with standard low-voltage circuits commonly found in commercial heating applications. It functions by generating a voltage proportional to the temperature difference between its two junctions, which can then be used to control the operation of the heating system. This product is designed for durability and reliability, ensuring consistent performance in demanding commercial environments.
