How to accurately applied bimetallic thermometer?

In the industrial production field temperature measurement using the most common is the bimetallic thermometer, this is the most common site in addition to the pressure gauge using measuring instrument. However in the application process is to be able to present a brief measurement deviation, in addition to the situation factors, such as the wrong application is also incur a elements of bimetallic thermometer present deviation. The bimetallic thermometer how accurate application? 1, the bimetallic thermometer immersed in the measured medium length of the maintenance required is less than the length of the thermal components, individual immersion length is 100 mm, 0 50 ℃ range in less than 150 mm in length, in order to ensure the accuracy of measurement. 2, bimetallic thermometer and transport in the preservation and application of device, should prevent collision pipe maintenance, do not make maintenance tube winding variant and the table when the wrench application. 3, all kinds of bimetallic thermometer should not be used for measuring closed containers within the medium temperature, electric contact thermometer should be paid attention to loop, the application of vibration circumstances. 4, in the case of the deformity application thermometer should be test on schedule. Individual is every six months. Electric contact thermometer should not be under the intense shock task, lest affect the strong sexual contact. Through the process of the above content, the accurate application of bimetallic thermometer had certain understanding. Hope everybody accurate application in the application of double metal thermometer, lest affect for the application of the bimetallic thermometer happened.
