Thermal resistance classification and main advantages - Shanghai dragon instrument electric appliance co. , LTD

Thermal resistance classification: regular heat resistance from thermal resistance temperature measurement principle can see, measurement of the temperature change is through to direct measurement of the thermal resistance of the change. Therefore, line etc. Various kinds of wire resistance change of the thermal resistance body can affect the temperature measurement. Armored thermal resistance sheathed thermal resistance is by temperature sensor ( The resistor body) , wire, insulation materials and stainless steel shell of solid ordinary for phi 2 - its diameter - Phi is 8 mm, xiaoke phi mm compared with ordinary thermistor, has the following advantages. Small volume, the internal air gap, thermal inertia, small measurement lag; Good mechanical performance, vibration resistance and impact resistance; Can bend, easy installation; Use the long service life. End heat resistance end appearance of thermal resistance inductance temperature components by a special disposal of resistance wire winding and become, near the end compared with ordinary axial thermal resistance thermometer, it can be more accurate, reflect the actual practice of end face temperature quickly and is suitable for the bearing shell and other parts of end face temperature measurement. Flameproof thermal barrier explosion limits of a hinge type thermal resistance with special structure within the junction box, because of the influence of the sparks or electric arc, the shell of explosive gas mixture is limited within the junction box, consumption will not cause excessive explosion at the scene. Explosion-proof thermal resistance can be used in the bla Explosion risk of b3c temperature measurement.
