The application of WSS bimetallic thermometer

WSS bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. Can be directly measured in the process of various production - 80℃- Liquid + 500 ℃ range steam and gas medium temperature. Bimetallic thermometer is made of round shape into threaded heat dual metallic piece as temperature sensing element, and put it in a protective sleeve, one end fixed ( Fixed end) And the other end, The free end) Connection on a thin shaft, shaft end is equipped with a pointer. When the temperature changes, temperature sensing element of the free end immediately rotation, thus fine axis pointer to produce angular displacement, indicates that the change in temperature on the dial. Due to the temperature sensing element has a linear relation with temperature changes, WSS bimetallic thermometer pointer indicated by the location of the measured temperature value is. WSS bimetallic thermometer thermometer is a very high cost performance, we choose this thermometer, with peace of mind, because this kind of thermometer is not easy to damage, the thermometer from the design principle and the structure has a waterproof, anti-corrosion, explosion-proof, resistant to vibration, intuitive, easy reading, no mercury pollution, strong and durable, etc. Need to measure the temperature of the environment will not cause any pollution, in addition, the use of this kind of thermometer method is easy to learn, at the time of using reading is very convenient, we choose this thermometer is to choose the rest assured. So received numerous users choice, after the application of it will be more and more. WISS bimetallic thermometer broke through the limitations of many traditional thermometer, whether the accuracy of temperature measurement, or environmental protection, is very reliable. This thermometer price is very economic, and because of this thermometer USES is 304 stainless steel material, so that the quality of the thermometer is very good influence WSS series bimetallic temperature insertion depth, there are two factors: the first is the range of measuring temperature, because the measuring temperature range determines the length of the bimetal induction flat ( Double metal sensors installed in the bottom of the heat pipe) 。 In general, from heat tube end, at least 50 mm, that is more than 50 mm length is ok. The second has to do with WSS series bimetallic thermometer installation, for example, the said pipe with WSS series bimetallic thermometer or if the connection pipes installed base flange, etc. , to count the length of these parts are. WSS bimetallic thermometer principle is applied thermal expansion principle of temperature measurement, belong to solid expansion thermometer. 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, 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.
