Thermal Resistance

Armored RTD 1. General Armored Pt. thermal resistor as a temperature transmitter is used to measure the temperature of liquid, steam, gas medium and the solid surface,ranging-200°C to 500°C. It is noted for their flexibility, wear resistance, vibration resistance and high temperature resistance. The outer protective tube of the armored thermo element is made of stainless steel and in which high density oxide is used as the insulating layer, so then, it is pollution resistance and enough mechanical strength, in order to meet the adverse circumstances. 2. Principal of operation The resistance value of Pt. filament will get changes with the change of temp. and the display meter will show the relative temp. value of resistance of Pt. filament. 3.
