At the request of the bimetallic thermometer production technology on how much you know?

Can say, our country on the bimetallic thermometer technology is perfect, the bimetallic thermometer as a fine instrument of temperature measurement, temperature measurement has an important influence on the produce. So not only need the function request, at the same time also need a request of the technique. Here are to say to you about some technical problems of bimetallic thermometer. 1, bimetallic thermometer scribed line on the dial, Numbers, and the rest of the tag should be complete, clear and accurate. 2, bimetallic thermometer stronger parts removed, shall not be loose, can not have corrosion, average maintenance should be strong, with light. 3, bimetallic thermometer, glass or other lit materials used in the header should be lit, shall not hinder accurate readings flaws or damage. 4, bimetallic thermometer pointer should cover ( Into) A quarter - the shortest dividing line 3/4, pointer instigated the width should not surpass the shortest dividing line width. 5, bimetallic thermometer pointer and dial the three-dimensional interval should be not less than 5 mm, but should not involve dial, bimetallic thermometer to the adjustable Angle of the review should be from the axial ( Or radial) Status to the radial ( Or axial) Position in the whole process of stop. 6, if necessary, shall be marked on the thermometer dial production factory name ( Or factory standard) , model, factory number, international temperature scale degrees Celsius tags & other; ℃” , accuracy grades, and measuring appliance production s production allow card marked with Numbers. Electric contact thermometer should also contact the extra power indicate on the dial or shell, contact the highest task voltage ( Exchange or dc) , current, grounding terminals. 7, in case the temperature is 15 -- 35 ' C, 85% of absolute humidity town, the output terminal of electric contact thermometer and earthing terminal ( Or shell) And between the output terminals of the insulation resistance between delimit value should not be less than national. Bimetallic thermometer on skill requirements, not only can make a range of more accurate, but also can make enterprise, reduce the loss in the production.
