Thermal Installation Methods for Thermistors and Thermocouples

Installing thermal resistors and thermocouples for reliable and accurate temperature measurement is a safe consideration, but it should also facilitate maintenance and ensure that equipment and production operations are not affected. To meet the above requirements, please pay attention to the following points when selecting the installation location and insertion depth of thermocouples and thermistors. 1, There must be a reasonable selection of measurement points that are sufficient for measuring the thermal resistance of media and clients, as well as nearby valves, elbow thermocouples, and thermal communication to avoid thermal installation of electrical equipment or thermal resistance.

Thermal resistance, heat transfer, heat loss, and thermocouple protection tubes must have sufficient depth to reduce measurement errors. The common purpose of measuring the fluid temperature in the core pipeline using thermocouples is to measure the center of the inserted pipeline (vertically installed or tilted).

It is necessary to choose fluid tube diameter measurement, such as 200mm, 100mm thermocouple or thermistor insertion depth. Temperature measurement of high-temperature fluids under high pressure and high speed (such as main steam temperature fracture). The protective tube is used to prevent the effect of light, and the fluid protective cover and liquid protective cover that reduces resistance can be inserted to collect heat from the thermocouple. It must be no less than 75 millimeters. The depth of the thermocouple protection tube plug should be shallow, and the main steam pipeline should be inserted.

The standard insertion depth for armored thermocouples with thermal sleeves is 100mm; The exhaust gas that needs to be measured has an exhaust temperature, a flue diameter of 1.4 meters, and an RTD or thermocouple insertion depth greater than the original insertion depth of 1 meter. You will need to protect the installation and housing or support frame that needs to be installed vertically. How to install a car seat with two thermocouples and a thermocouple thread, and measure the size of thermocouples and thermal resistors online.

The two holes of the pipeline can be equipped with screw seats according to the diameter. Thin plate welding thread. The table with thread insertion has a well welded hole, pipeline, and gauge thread. Four thermocouples or thermal resistance welding threads with precession. According to the thermocouple, RTD or wiring, this is the wiring diagram of a dial connection junction box corresponding to the display unit. The temperature of the junction box, please pay attention to the measurement of the blood vessel wall, within the range of 0 to 100 ℃, and the medium will not come into contact. The installation location of thermal resistors or thermocouples needs to be considered for ease of maintenance and upkeep.
