Installation of thermal resistance and thermocouple, reliable and accurate temperature measurement is a safe care, but it should help facilitate maintenance, and the operation of equipment and production operations will not be affected. In order to meet the above requirements, the installation position and insertion depth of thermocouples and thermal resistances, please pay attention to the following points. One, there must be a reasonable selection of measurement points, sufficient for the measurement of the thermal resistance of the media and the client, and the exchange between nearby valves, elbow thermocouples, and heat trying to avoid thermal installation of electrical equipment or thermal resistance. Thermal resistance and heat transfer and heat loss and thermocouple protection tube to reduce measurement errors, thermocouple and thermal resistance, it must have sufficient depth. Thermocouples measure the temperature of the core pipe fluid, and a common purpose is to measure the center of the inserted pipe (vertical installation or inclined). Must choose fluid pipe diameter measurement, for example, 200 mm, 100 mm thermocouple or thermal resistance insertion depth. Temperature measurement of high temperature fluid, high pressure, high speed (for example, the main steam temperature fracture), the protective tube light to prevent the action of the fluid protective cover and the liquid protective cover to reduce the resistance You can insert the effect of heat set by the thermocouple. It must be no less than 75 mm, the thermocouple protection pipe plug should be shallow, and the main steam pipe should be inserted. The insertion depth of the sheathed thermocouple thermocouple is 100mm standard; the exhaust gas temperature needs to be measured at the exhaust gas temperature, the flue diameter is from 1 meter to 4 meters, the RTD or thermocouple insertion depth is greater than the original insertion depth of 1 meter, You will need to protect the installation and housing or support frame for vertical installation. How to install two thermocouples and thermoelectrics A threaded car seat, in-line measurement of the size of thermocouples and thermal resistance. The two holes of the pipe can be seated according to the diameter of the screw. Thin plate welding thread. The thread is inserted into the table, with a hole well welded, the thread for the pipe and the gauge table. Good four thermocouples or thermal resistance welding thread precession. According to thermocouple, RTD or wiring, this is the wiring diagram of the junction box corresponding to a dial-up connection with the display unit. Please note that the temperature of the junction box and junction box should be measured with the blood vessel wall so as not to exceed the range from 0 to 100 ℃, and the medium will not come into contact. The installation location of the thermal resistance or thermocouple needs to be considered for easy repair and maintenance.
