Bimetallic thermometer when installation should pay attention to what time is it?

Bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. Bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. Working principle of bimetallic thermometer will orbit around a formation of threaded heat bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end, the other end of the connection on a thin shaft, called the free end. Spool at the free end is equipped with a pointer. When the temperature changes, the resulting thermal devices the free end of the rotation, drive the thin axis from the Angle of the pointer changes, corresponding temperature indicator on the dial. Bimetallic thermometer is applied in chemical and petrochemical industry; Power engineering; Field of food. Construction machinery and general factory. The following instruments to tell everyone bimetallic thermometer which points need to be paid attention to during installation. When installing a bimetallic temperature time need to pay attention to the following: 1. Bimetallic thermometer installed, do not twist header; 2. Observe the thermometer work is normal. Pointer to the header of the thermometer should be installed vertically, shaft should be located in the middle of the dial hole when tapping meter shell, pointer position should not change. Bulb thermometer must be completely submerged, immersion length shall comply with the requirements of the product's instructions or completely submerged. 3. If it is the first time test thermometer, check point should be evenly distributed in the entire measuring range ( Must include measurement, the lower limit) And shall not be less than four points. Have 0 ℃ thermometer should include 0 ℃. The subsequent verification and use of verification shall not be less than three points. 4. Directly installed on the device or selection with a protection tube, should pay attention to accurate temperature measurement, safety examination and maintenance is convenient, and does not affect the equipment operation and production operation; 5. Choose suitable for the position of measuring points and try to avoid the valve, elbow and pipe and equipment near the corner of the bimetallic thermometer. 6. Bimetallic thermometer with a protective casing, in order to reduce the measurement error, should ensure adequate insertion depth. 7. Don't bend heat pipe or random wobble header.
