The practical application of surface thermometer

In chemical production, there is a special kind of equipment, by the use of material in the manufacturing process of high temperature and high pressure, explosive, toxic, corrosion characteristics influence, columns are not allowed to have too many side of the interface. In addition to flow in and out of line, reserved for instrument only rarely interface, even the whole tower surface instrument interface, construction installation process more freely in open hole on the side of the tower is forbidden to install instruments. This situation determines the temperature of the traditional instrument installation method is not practical, and implements quality craft production requires testing tower temperature, so you need to use other ways of temperature detection, and the surface thermometer arises at the historic moment. Surface thermometer is the temperature test instrument of temperature sensing element installed in the outer surface of the container line, testing equipment, the surface temperature of the container. Although the surface temperature of the container is lower than the temperature of the container material, but from the surface temperature of the container may be generally inferred material temperature inside the equipment container, in order to determine the material of the degree of response to provide numerical reference to production control. The surface temperature by measuring equipment container to know container material temperature method, the numerical accuracy than traditional plug-in temperature instrument is poor, temperature measurement error is bigger. In order to improve the accuracy of detection of surface temperature to reduce the numerical error, on the surface thermometer to construction in strict accordance with the requirements of installation, installation location choice to consider the effect of environmental factors on temperature measurement, improve the accuracy of surface thermometer temperature as possible.
