Pay attention to the point of various kinds of temperature instrument installation

Temperature instrument installation location should fall in temperature sensitive measured medium and representative, unfavorable choose resistance components such as valve accessories and medium flow beam in a corner and the place of vibration is larger. 1. The installation position of thermocouple thermometer, stay away from strong magnetic field. 2. Temperature instrument ( Such as: thermocouple thermometer, hot resistance thermometer, bimetallic thermometer, pressure type thermometer, etc. ) Should be installed in accurately reflect the position of the medium temperature. 3. Installed on the technology road of temperature measuring element should be perpendicular to the center line of the pipeline or tilted 45 & deg; , insert depth should be greater than 250 mm or at a center line, insert the appropriate direction and reverse or vertical measured medium. Nominal pipe diameter less than 80 mm can be installed in the elbow or expansion of tube. 4. Bimetallic thermometer when installation, calibration disk should facilitate observation, straight mercury thermometer should not be installed horizontally. 5. The temperature of the thermometer on the surface should be closely contact with the surface under test, fixed firmly. 6. Pressure type thermometer when installation, should make the bulb all immersed in the measured medium, capillary should be equipped in Angle or tube slot, and to prevent a mechanical strain. Capillary fixed should not knock, bending radius should not less than 50 mm. Should be no mechanical vibration, the surrounding environment and temperature should not be too large, such as heat insulation measures should be taken when inevitable. 7. Installed in a fixed granules medium temperature meter, protection measures should be taken to prevent wear and tear. 8. Temperature instrument joint thread should match the pipe threads. 9. When the temperature meter installed horizontally and insertion depth is longer or in high temperature equipment, should be bending prevention measures.
