What structure characteristics of the socket type heat resistance?

1。 Armored thermal resistance: armored thermal resistance is by thermal components ( The resistor body) , wire, insulation materials, stainless steel casing with a solid body, it's common for from 2 ~ 8 mm outside diameter, xiaoke phi mm. Compared with the normal thermal resistance, it has the following advantages: ( 1) Small volume, external no air gap, thermal inertia, small measuring hysteresis; （ 2) Good mechanical function, resistance to vibration, shock; （ 3) Can bend, facilitate device ( 4) Use the long service life. 2. Transverse thermal resistance: transverse thermal resistance temperature sensing element by special disposal of the resistance of the wire winding, close to the face in the thermometer. Compared with ordinary axial heat resistance, it can more correctly and swiftly to reflect the practice of end face being measured temperature, suitable for measuring temperature bearing and other parts of the face.

3。 Flameproof thermal resistance: flameproof thermal resistance specially constructed junction box, its shell external explosive mixed gas by by a spark or arc effects such as explosion limits within the junction box, that wouldn't make consumption field explosion. Flameproof thermal resistance can be used in the Bla ~ B3c zone with the explosion risk level place of temperature measurement.

4。 Knowledge of thermal resistance: industrial commonly used thermal resistance temperature components ( The resistor body) The structure and characteristics. The thermal resistance from http://www. wuxiyibiao。 Com/temperature measuring principle of knowable, measured the change in temperature is measured indirectly through the change of the thermal resistance tolerance, therefore, the wires of a thermal resistance and other kinds of wire resistance change will affect temperature measurement. To eliminate the influence of the lead resistance with a use three wire or four wire system.
