Bimetallic thermometer installed points have?

Bimetallic thermometer products can directly measure the 80 ℃ - in the process of production Liquid + 500 ℃ range steam and gas medium temperature. Users to install in the process of the bimetallic thermometer is more attention should be paid to the problem, this instrument is to introduce specific bimetallic thermometer installation key points, hope you in use have a very good help! Bimetallic thermometer installed points: ( 1) In order to make the measurement of thermal resistance end and have good heat exchange between the measured medium, should be a reasonable choice of observation, try to avoid the valve, elbow and pipe and equipment near the corner of installing heat resistance. ( 2) With a protective casing thermal resistance of heat transfer and heat loss, in order to reduce the measurement error, thermocouple and thermal resistance should have enough insert depth: a, for heat resistance temperature center fluid, usually should be measuring end is inserted into the pipe center ( Vertical or inclined installation) 。 As the current body of pipe diameter is 200 mm, the thermal resistance should choose insert depth 100 mm; B, for high temperature and high pressure and high velocity of temperature measurement, Such as main steam temperature) , in order to reduce cases of fluid resistance and prevent cases break under the action of a fluid, can take protecting tube shallow inserted way or use hot shell heat resistance. Shallow inserted type thermal resistance to protect casing, and its depth into the steam pipe should be no less than 75 mm; On a hot resistance standard insert depth of 100 mm; C, if is need to measure the temperature of flue gas, although the flue is 4 m in diameter, the heat resistance of insertion depth of 1 m; D, when measuring the original insertion depth of more than 1 m, shall be installed vertically, as far as possible or add racks and protect casing. The above is the main points of the bimetallic thermometer installed, hope when use can bring help to you!
