Thermal resistance of short circuit and open circuit method to resolve the problem?

More people perception of thermocouple and thermal resistance are also more and more. We know through various channels and analyze the thermocouple related technology, for the majority of netizens to present various industry knowledge.

then we have to get to know the heat resistance of short circuit and open circuit method to resolve the problem?

in general, thermal resistance in the process of application is relatively smooth, but sometimes also may fail, but one of the most common is open circuit and short circuit. And open circuit, usually because of heat resistance wire is too thin, caused by the following simple we come to know about the thermal resistance of short circuit and open circuit problem processing method.

open circuit and short circuit could have easily tell commonly, just need a multimeter. Use a multimeter measure Ω 'x 1' file, such as the measured value is less than R0, could be short circuit; If the measuring instructions to infinity, so can determine cut-off. The short circuit is easy to handle, as long as does not affect the resistance wire length and thickness, short circuit for dry, reinforced insulation. If is open circuit, the processing must change the length of the wire which will impact resistance, so only change new resistance body, but to repair welding, after welding to be calibrated before use.

in addition, if the thermal resistance of the display instrument display value is lower than the actual value or value for instability, so may be protecting tube with dirt, so mainly to remove the dirt. But if shown negative, then may be hot resistance connection errors or thermal resistance is short circuit, so as long as the correct wiring and deal with the short circuit can continue to use.
