Do you know how to prevent the damage of the bimetallic thermometer

Not forever, nor for permanent use, thermometer, too, won't be able to used for a long time, it is a good thermometer has broken, many of his peers also encountered such a problem, how to make the service life of the bimetallic thermometer is longer? , one of the most important problem is the installation problem of the installation position of bimetallic thermometer take source components, stay away from strong magnetic field, take the source component in the process piping installation shall meet the following requirements: 1, and process piping installation, vertical center line should take the source parts and the process piping vertical axis intersection. 2, in the corner of process piping installation, should be against the medium flow direction, take the source components centerline should coincide with the center line of the process piping. 3, process piping and 45 & deg; Oblique 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. 4, installed on the pipe temperature, time, take out the space required for the thermometer components should be considered in the following circumstances, the installation of the thermometer should be adopted to expand tube: 1, all kinds of glass liquid thermometer in DN< Piping installation of 50 mm. 2, thermocouple, heat resistance, bimetallic thermometer in DN< 80 mm pipes installed, to facilitate observation at the scene. Second, the transportation problem: after some customers to buy the bimetallic thermometer, when ready to use, found the thermometer is broken, but at the time of merchants detection is good, is this why? Most of the problem is transportation. Bimetallic thermometer transportation may be big problems, such as express delivery party ( Due to bad packing, carton packing, or packing are not sealed) On the way, it broke, it will directly cause the bimetallic thermometer precision error is larger. Bimetallic thermometer is made up of components and steel wire welded together, if you have any fell on the way, the components and wire will fall off, thus pointer no longer work, or dropped the element spacing, the deformation of the position of the pointer than there will be changes in such things, and so on. Therefore in the process of transportation, had better be packed in wooden cases, wrapped with paper towel to put inside, don't let there is space generally will not have what problem, this is the purchasers and suppliers often ignore the problem. The problem should be noticed.
