Four types and structures of thermal resistance

(1) Proficient thermal resistors Common industrial thermal resistance temperature sensing elements (resistors) It is known from the temperature measurement principle of thermal resistance that the change in measured temperature is directly measured by the change in resistance of the thermal resistance. Therefore, the thermal resistance Changes in various wire resistances, such as lead wires, can affect temperature measurements. In order to eliminate the influence of the lead resistance, the three-wire or four-wire system is adopted in the same way. For details, refer to the first section of Chapter III of this paper.

(2) Armored thermal resistor Armored thermal resistor is a solid body composed of a temperature sensing element (resistor), lead wire, insulating material, and stainless steel bushing. Its outer diameter is generally φ2~φ8mm, and the minimum is up to φmm. .

Compared with common thermal resistance, it has the following advantages: 1 small size, no internal air gap, thermal inertia, small measurement lag; 2 good mechanical properties, vibration resistance, impact resistance; 3 can bend, easy to install 4 long service life .

(3) End face thermal resistance The end face thermal resistance temperature sensing element is wound by a specially treated resistance wire, and is closely attached to the end face of the thermometer. Compared with the general axial thermal resistance, it can more accurately and quickly reflect the actual surface of the measured end face. Temperature, suitable for measuring the end face temperature of bearings and other components.

(4) Flameproof RTD flameproof RTDs are limited to the junction box by the junction box with a special structure, and the explosion of the explosive gas mixture inside the shell due to sparks or arcs is limited to the explosion at the production site. . Flameproof RTDs can be used for temperature measurement in explosion-hazardous areas in Bla-B3c zones.
