WSS double metal thermometer is a kind of field testing instrument for measuring low and medium temperature. Can be directly measured in various production process of -80 C C -+500 C range of liquid vapor and gas medium temperature. Bimetallic thermometer in the field display temperature, intuitive and convenient, safe and reliable, long service life; a variety of structural forms, can meet different requirements.
Description of the problem
The pointer thermometer is caused, and the electrolyte for 3 hours, a tube of 1 titanium protective tube double metal thermometer is I have no corrosion temperature double metal band mobile operating 120 degrees for chromium electrolytic cell plating, the surface of the workpiece does not make hot and cold chrome heat treatment has been difficult to know.
Analysis problem
Titanium is difficult to metal corrosion, electrolysis, this phenomenon is very obvious reason is that the purity of titanium is not enough. However, the market to buy a protective tube thermometer dual metal high purity titanium is relatively difficult, the cost is too high.
Solution scheme
And corrosion resistance, is in the jacket or protective tube of titanium electrolytic protection difficult, it is recommended to choose the plastic pipe material
