WSS - 381 bimetallic thermometer daily inspection work

WSS - Bimetallic thermometer daily checking work WSS - 381 381 bimetallic thermometer principle is applied thermal expansion principle of temperature measurement, belong to solid expansion thermometer. WSS - 381 bimetallic thermometer 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. WSS - 381 bimetallic thermometer 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. WSS - Bimetallic thermometer measuring temperature range for roughly 381: - 80 ℃ to 550 ℃, but the precision of the extremely low and high temperature is not high. WSS - Bimetallic thermometer principle determines the WSS - 381 381 bimetallic thermometer good vibration resistance, easy reading, WSS - 381 bimetallic thermometer is widely applicable to various kinds of industrial production and equipment. WSS - 381 double metal thermometer manufacturers daily inspection was carried out on the double metal surface to wipe, check meter inside water, dial is fuzzy, the case is in good condition, seismic WSS - Oil within 381 bimetallic thermometer is turbid, whether to affect the value view, whether the instrument range. Daily inspection of WSS - 381 bimetallic thermometer casing leak detection with pipe welding place, need to wipe the leak detection liquid after the leak detection. WSS - 381 double metal thermometer manufacturers daily inspection, need to check WSS - 381 bimetallic thermometer indicates whether the value with stand accused of machine or under the condition of temperature values are consistent or within the allowed error range. WSS - 381 bimetallic thermometer, such as numerical mistakes, the thermometer must be removed, disassembled confirm WSS - Whether the bimetallic thermometer contains 381 casing, such as no casing not to remove it. Remove the WSS - after inspection 381 whether deformation, bimetallic thermometer sensor gauge pointer to loosen, heating or cooling to check, check to see if the temperature changes, whether pointer moving smoothly. Check whether the casing is contains a lot of water or ice blocking impurities, and clean or replace. WSS - 381 double metal thermometer manufacturers yard use WSS - now Bimetallic thermometer range for the most part is 381 - 40 ℃ ~ 80 ℃, the accuracy level most of 1. 0, part 1. 5.
