How to prolong the life of the bimetallic thermometer?

Most likely at the time of using a thermometer, if the thermometer damage may have taken place in the first reaction is to change the new bai, but this is not only cost also spent time, but if it is some table is a leak or defective issues such as was in a hurry too get a new one? There's no need to, the following introduce bimetallic thermometer in the main obstacle and matters needing attention: bimetallic thermometer common problems are: 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. Bimetallic thermometer in use there are many considerations: (1) in order to guarantee the correctness of the bimetallic thermometer, thermal tube immersed in medium depth depends on different heat pipe length should be within the range of 95 ~ 130 mm (2) readings implementation should be vertical (3) and dial bimetallic thermometer (after normal use Generally no more than one year) Shall be carried out according to the relevant test procedures of the bimetallic thermometer calibration on a regular basis. (4) hot shell encountered in the process of bimetallic thermometer use damaged need to replace, then only 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) bimetallic thermometer in the transport, storage, installation, use should be avoided in the process of collision, including table, heat pipe, pan, causing damage or sensitivity and accuracy of the thermometer is inaccurate. 6. The normal work condition of bimetallic thermometer is: ( - 25-85) ° C, relative humidity is 5% ~ 100% if avoid these problems, will prolong the life of the thermometer?
