Thermal resistance is the principle to measure the temperature of the application of the metal when the temperature changes. According to the protection tube structure is divided into assembly (detachable) and armoured type (non removable, built-in platinum resistance). At present, the assembly type thermal resistance which is used in the field mainly includes the platinum thermal resistance and the index number of the Pt100, and the heat resistance of the Cu50 is the two major types of the copper heat resistance.

Industrial WZ series assembly type thermal resistance can be directly connected with the use of the two meter. The liquid, vapor and gas media and the temperature of the solid surface can be measured in various production processes from -200 to 420.

Because it has good electrical output characteristics, it can provide accurate temperature change signal for display instrument, recorder, regulator, scanner, data recorder and computer.

The structure - assembled thermal resistance

The assembling type thermal resistance is mainly composed of a junction box, a protective tube, a connecting terminal, an insulating sleeve and a temperature sensing element.
