How to choose the bimetallic thermometer in the actual production?

Mention bimetallic thermometer, believes that many professionals are familiar with, especially for those who engaged in industrial production, if you want to measure low and medium temperature at the scene, it is an indispensable instrument. Bimetallic thermometer is a round shape into 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 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. Bimetallic thermometer is applied in chemical and petrochemical industry; Power engineering; Field of food. Construction machinery and general factory. That how to choose the bimetallic thermometer? When we are in the choice of the bimetallic thermometer, the first thing to consider is our actual production needs, this is what we should be the primary consideration. Some industrial production will need some high precision thermometer. For example, medicine, chemical industry production is in need of some high precision thermometer, to meet for minor parameters of small amplitude adjustment and improvement, in order to meet the needs of production. For some of the same for the production process requirement is not very strict in the industrial production, do not need to select the high accuracy, practical give priority to, also want to consider the factors of price, practical is the best.
