Question:

What are the problems that should be paid attention to when measuring temperature with temperature measuring parts, thermocouples or thermal resistors?

What are the problems that should be paid attention to when measuring temperature with temperature measuring parts, thermocouples or thermal resistors?

Answer:

The thermocouple and thermal resistor shall avoid severe collisions and bumps during storage, transportation, carrying, installation and use.Thermocouple, thermal resistance, when measuring the temperature field, avoid quench and sudden heat.When in use, the required depth of insertion shall be reached, otherwise the accuracy of measurement can not be guaranteed.
It shall be used according to the environment and atmosphere provided by the thermocouple and the thermal resistor, otherwise the service life and accuracy will be seriously affected.The temperature limit of the temperature field to be measured should be close to the upper limit of the measurement range, such as the long-term work at the upper limit of the measurement range, it may affect the life of 2/3.
When installing in high temperature environment, high temperature strength and deformation under high temperature should be taken into account.The influence of thermocouples and thermal resistance leads on measurement accuracy should be taken into full consideration. Thermocouple cable to the display device or the transmitter should be short and use the shield line as far as possible and should be used separately; wiring and power line, otherwise it will cause interference, affect the stability of the display.
