, the principle of thermal resistance in terms of temperature measurement

Thermal resistance of the main features are: high precision mechanical performance is good, not only volume is very small, the performance of the shock and vibration resistance is higher also, because you can bend it is easy to install, is the main points very long service life, low temperature in the whole area is belong to the common temperature detection device, and is widely used in industry of temperature measurement, all the friends contact heat resistance should know that in fact thermal resistance on the species is diverse, but should belong to common copper heat resistance and platinum thermal resistance.

in order to let everyone can more detailed understanding of thermal resistance, small make up to introduce four use more on market, and heat resistance types which are frequently used, is mainly: industrial heat resistance, end of the armored thermal resistance, heat resistance and heat resistance of explosion-proof explosion-proof. One, single coming up from the principle of thermal resistance temperature measurement analysis, changes in temperature is measured, mainly with the resistance of thermal resistance change, the lead in the thermal resistance, etc. , all of the wire resistance in the change, will affect the temperature of the measured; Second, armored thermal resistance is the main component can be divided into: insulation materials, heat element. Stainless steel casing and fuses, etc. , for its entire diameter phi - 2 Phi between 8 mm; Three, the thermal resistance of the heat of the components are made by a special resistance wire winding and become, so it is need to be close to in the end of the thermometer, how to compare general axial thermal resistance, can quickly and correctly reflect the temperature of end face on the actual, suit to use in the bearing shell, and other end face temperature measurement; Four, mainly rely on explosion-proof junction box, the electric arc and spark will directly cause the possibility of explosion, completely within the limit in the junction box, so the whole site is there will be no explosion phenomenon.
