Using bimetallic thermometer should know its use considerations and maintenance method

Bimetallic thermometer in use there are many considerations, can accurately test and prolong the service life of the following instrument to introduce the use of the bimetallic thermometer and maintenance. (1) in order to guarantee the correctness of the thermometer, the depth of the heat tube immersed medium depending on the different heat pipe length should be within the range of 95 ~ 130 mm (2) readings implementation should be vertical (3) and dial thermometers (after normal use Generally no more than one year) Shall be carried out according to the relevant test procedures of the industrial bimetallic thermometer calibration on a regular basis. (4) heat thermometer encountered in the use process need to replace the damaged, simply loose nut counterclockwise, then turn the tables, cases in equipment, then the new table core loading, don't make double metal spiral tube and at the bottom of the case, screw nut. (5) the thermometer in the transport, storage, installation, use should be avoided in the process of collision, including table, heat pipe, pan, causing bad or sensitivity and precision of the thermometer is inaccurate. 6. The normal work condition of bimetallic thermometer is: ( - 25-85) ° C, relative humidity is 5% ~ 100% between the bimetallic thermometer should be how to repair? Bimetallic thermometer if damaged, we have to replace the new table is given priority to, if produce such as oil leakage, flaw can be generally returned to the factory maintenance, but will take into consideration the maintenance fee. Bimetallic thermometer common fault mainly include: no precision, oil gas leak, pointer jump needle, needle loose, dial, glass table cover damage, etc. , these problems are because of the loss caused by improper operation or normal in the process of using, so we in the use of bimetallic thermometer is be used in accordance with the specifications, and regular inspection and maintenance, to ensure that the bimetallic thermometer display accurate, reduce the cost in production.
