Armored thermistor is a common temperature measurement device widely used in industries such as petroleum, chemical, power, metallurgy, etc. However, due to harsh working conditions, improper use, and other reasons, armored thermistors may experience various malfunctions. Below, we will discussTiankang Armored ThermistorAnalyze common faults and propose corresponding solutions.

　　

Armored thermistor reflects temperature changes by measuring changes in resistance. When the temperature of the measured medium changes, the resistance value of the thermistor will also change accordingly. By measuring this resistance value, the temperature of the measured medium can be obtained. However, in actual use, the armored thermistor may experience the following faults:

　　

1. No output signal from the thermistor: This may be due to a broken or poorly connected circuit inside the thermistor. The solution is to check the internal circuit of the armored thermal resistor. If there are any broken or poorly connected areas, they need to be repaired in a timely manner.

　　

2. Unstable output signal of thermistor: This may be due to the working environment temperature of the thermistor being too high or too low, or the flow rate of the measured medium being too fast. The processing method is to adjust the working environment of the thermistor and the flow rate of the measured medium to maintain it within an appropriate range.

　　

3. The output signal of the thermistor is either too large or too small: This may be due to the zero or full offset of the thermistor. The processing method is to perform zero calibration and full-scale calibration to restore the output signal of the thermistor to the normal range.

　　

4. The thermistor cannot function properly: This may be due to damage to the external structure of the thermistor or aging of internal components. The solution is to check the external structure of the thermal resistor, and if there are any damaged areas, they need to be repaired in a timely manner. At the same time, it is also necessary to regularly replace the internal components of the thermistor to ensure its normal operation.

　　

When dealing with faults in Tiankang armored thermal resistors, the following points should also be noted:

　　

1. Before performing any operation, it is necessary to disconnect the power supply to prevent electric shock.

　　

2. When inspecting and repairing thermal resistors, specialized tools and equipment are required to prevent secondary damage to the resistors.

　　

3. When replacing the internal components of the thermistor, it is necessary to choose a new component with the same performance as the original component to ensure its normal operation.

　　

In general, although various faults may occur in Tiankang armored thermal resistors, as long as we master the correct fault analysis and handling methods, we can effectively solve these problems and ensure the normal operation of thermal resistors.
