Different structures of heat resistance on the use of different

A, flameproof thermal resistance: the structure of the thermal resistance is mainly through a special terminal box, the outer and inner explosive and mixed gas, because of the influence of sparks or electric arc and other the possibility of explosion, directly to eliminate inside connection box, so in the production of the scene is not appear the phenomenon of explosion, and the thermal resistance of the flameproof can directly for the dangerous sites within the temperature measurement. End of the second, heat resistance, face type of the thermal resistance of the temperature sensing element is mainly through the special processing, the resistance wire is through special processing of winding, and so is the stick close on the end of the thermometer, if compared with the normal thermal resistance of axial, can more quickly and accurately will be end in a timely manner to reflect the actual temperature measurement, especially suitable for use in bearings or other parts of the face. Three, proficient in heat resistance type: relatively commonly used in the industrial heat resistance on the device structure and characteristics of heat, actually, and heat resistance temperature measurement principle of basic same, by measuring the changes in temperature on mainly through the thermal resistance of the resistance measurement, so the heat resistance between the lead and different heat resistance of the wire changes, will directly affect the temperature of the measured values, in order to effectively will lead to eliminate the influence of resistance may be, can be used at the same time four wire or three wire system.
