Pipe installed on the considerations of the thermometer

Thermometer is daily life, industry, medicine, environmental protection, chemical, petroleum etc. The most commonly encountered in the field of a physical device. The thermometer is the basic ways of measuring temperature, easy to read temperature directly. Thermometer is more and more widely used in recent years, the line, but the pipe installed on the thermometer should know what? The following specific said: take the source component installation location should choose in the medium temperature sensitivity and representative place of temperature change, don't choose the near the valve components such as resistance and medium flow beam in a corner and the place of vibration is larger. Thermocouple installation location of the source components, stay away from strong magnetic field. Temperature in source components in the process piping installation shall meet the following requirements: one, and the vertical installation, process piping center line should take the source parts and the process pipe axis vertical intersection. Second, in the corner of process piping installation, should be against the medium flow direction, take the source component centerline should coincide with the center line of the process piping. Third, with the process piping 45 & deg; C diagonal when installation, should be against the medium flow direction, take the source should be a center line of fellowship with the center line of the process piping. Specification requirements: (1) on the pipe diameter smaller pipe installation of thermal resistance, thermocouple, bimetallic thermometer, pipe diameter should be expanded to 80 mm or 100 mm. (2) if the pipe need to enlarge of less than 80 to 80 after installation, a specific algorithm is: - M; Y % n / b” { 5T,x2B1. Gas measurement: casing diameter * 10 + 50 & # 39; B/Z2H) Z,c7O- K2. Liquid measurement: casing diameter * 5 + 50 from the pipe above the installation requirements of the thermometer can see, the installation of pipeline thermometer is very strict, because only in this way can the strict, accurate measure the temperature of the liquid in the pipeline, only the installation accuracy, does not bring unnecessary trouble to our work!
