Extend the life of the bimetallic thermometer

Bimetallic thermometer is the most common used in instruments and meters. Often people using bimetallic thermometer can know, in the process of application also will often present deviation. The protection of the bimetallic thermometer and usual tasks is very important. If you don't stop the excellent protection, serious influence the measuring accuracy and life. Below the way of the factors affecting the service life of bimetallic thermometer and extend life. 1, in industrial enterprises, the workpiece chrome electroplating cell, using titanium pipe as the protection of the bimetallic thermometer, the application of three hours at the task of 120 ℃ temperatures electrolyte is corrupt the bimetallic strip, so that the pointer thermometer, don't know it would be difficult to end the workpiece temperature chrome plated surface heat treatment. 2, titanium is a kind of not easy to corrupt, and electrolytic metal, this scene was evident reason is that the purity of titanium does not apply. But on the market to buy to high purity titanium for protecting tube bimetallic temperature calculation, and the cost is too high. 3, if outside the titanium protecting tube with a resistant to decay and electrochemical protection tube not easily, can be a very good life extends the application of the bimetallic thermometer. Decay resistance of plastic pipe is strong, good insulation, light quality, cheap price, is better than that of pure iron or mild steel at 120 ℃. The bimetallic thermometer outside diameter is 12 mm, is looking for plastic tube diameter is 12 mm. As 510 mm 500 mm long, plastic tubing blanking, and cooperated with hot glue a head, a head into the protecting tube. The above is to extend the life of the bimetallic thermometer method, hope in the use of some help to you!
