Precautions for the use of thermocouples and thermal resistors?

Precautions for the use of thermocouples and thermal resistors

1. Thermocouples and thermistors should be protected from severe collision and shaking during storage, transportation, carrying, installation, and use

Bo.

2. Thermocouples and thermal resistors should be placed in the measurement temperature field to prevent sudden cooling and heating.

3. When using, the depth of rule insertion should be reached, otherwise the accuracy of measurement cannot be guaranteed.

4. It should be used in an environment and atmosphere that follows the rules for thermocouples and thermistors, otherwise it will seriously affect the service life and precision

Degree.

5. The upper limit of the measured temperature field should be close to two-thirds of the upper limit of the measurement scale, such as during long-term operations in measurement

The upper limit of scale may affect its lifespan.

When installing in a high-temperature environment, full consideration should be given to maintaining the high-temperature strength of the pipe and the deformation under high-temperature conditions.

7. The impact of thermocouple and thermistor leads on measurement accuracy should be fully considered. Thermocouples and thermal resistors

The connecting wires of the display instrument or transmitter should be as short as possible and shielded wires should be used; When in use, it should be separated from the power line

Wiring, otherwise interference will occur, affecting the stability of the display.
