Bimetallic thermometer how to distinguish between the radial and axial?

Bimetallic thermometer is a common instrument of measuring temperature in low temperature field. In order to adapt to the needs of a variety of different installation environment, can according to the header and the connection mode of the heat pipe, bimetallic thermometer can be divided into radial bimetallic thermometer, axial bimetallic thermometer and universal type of bimetallic thermometer. So how do you distinguish is radial or axial? According to the above, we can see that the radial type bimetallic thermometer meter and heat pipe are parallel, show I word, so the radial type bimetallic thermometer thermometer is known as the type I; Type axial bimetallic thermometer meter and heat pipe is vertical, show the T word, because type axial bimetallic thermometer and can be called T thermometer. We know that this is only two in order to meet the needs of different installation environment, so they just look different, they work are the same, so their parameters can also be made the same.
