Industrial bimetallic thermometer can also be used as indoor thermometer

Many people impression industrial thermometer are rough, not beautiful in appearance, and indoor thermometer are some board thermometer, electronic thermometer, etc. In fact, industrial thermometer have 'wonderful work'! Magnets belongs to bimetallic thermometer thermometer, bimetallic thermometer is based on solid heat expansion principle, measuring temperature is usually put the two pieces of expansion coefficient difference is relatively large pieces of metal stitch welding together, constitute a bimetallic temperature sensing element. When the temperature changes, because the bimetallic strip of the materials of the two different linear expansion coefficient is relatively large, produce different expansion and contraction, leading to the curving deformation of bimetallic strip. As there are different according to different deformation amount of momentum transfer, the amount of rotation drive connection shaft, shaft drive at the other end of the indicating needle, indicating pointer is just on the correct reading, indicate the temperature. Magnet thermometer we usually use pipe surface temperature measured using in the industry, in fact it can also be used as indoor thermometer at the same time, using magnet adsorption characteristics of the installation, it can be adsorbed to the office of the iron filing cabinet, already beautiful for office life add to the fun, also for winter and summer air conditioning temperature monitoring. Note, do not use hand to stir the temperature sensing element behind the instrument, so as to avoid damage.
