Precautions for the use of thermocouples and thermal resistances

Precautions for the use of thermocouples and thermal resistances 1. Thermocouples and thermal resistances should be protected from severe bumps and bumps during storage, transportation, carrying, installation and use. 2. Thermocouples and thermal resistances can prevent sudden cooling and sudden heating when they are placed in the measurement temperature field. 3. When using, it should reach the regular insertion depth, otherwise the accuracy of the measurement cannot be guaranteed. 4. It should be used according to the environment and atmosphere of thermocouple and thermal resistance, otherwise it will seriously affect the service life and accuracy. 5. The temperature upper limit of the measured temperature field should be close to two-thirds of the upper limit of the measurement range. If the long-term operation is at the upper limit of the measurement range, its life may be affected. 6. When installing horizontally in a high temperature environment, the high temperature strength of the maintenance pipe and the deformation under high temperature conditions should be fully considered. 7. The influence of thermocouple and thermal resistance leads on measurement accuracy should be fully considered. The connection line from thermocouple, thermal resistance to indicator or transmitter should be as short as possible and shielded wire should be used; it should be separated from the power line during use, otherwise it will cause disturbance and affect the stability of the display.
