Armored Thermal Resistance

The outer protective sheath of the armored thermal resistance is made of stainless steel, and the interior is filled with high-density oxide insulator. Therefore, the armored thermal resistance has excellent anti-pollution performance and mechanical strength, making it suitable for installation in harsh environments.

The armored thermal resistance can be used to measure temperatures in the range of -200℃ to 600℃, and can be directly connected to secondary instruments with copper conductors. Owing to its favorable electrical output characteristics, the armored thermal resistance can provide accurate temperature change signals for indicators, recorders, regulators, scanners, data loggers and computers.

Working Principle

Working principle of armored thermal resistance: Under the effect of temperature, the resistance of the thermal resistance wire changes accordingly, and the display instrument will indicate the temperature value corresponding to the resistance value generated by the thermal resistance.
