What are the classification of the bimetallic thermometer way?

Bimetallic thermometer is a kind of low temperature field temperature measurement instrument. It can be directly measured various - in the process of production 50 ℃ ~ + 500 ℃ temperature range of liquid, steam and gas. It is widely used petrochemical, hvac equipment, industrial equipment, power plants, etc. As we know, different application fields, to the specification requirement of bimetallic thermometer is different also. Today let's talk about according to their different application fields, we can put the bimetallic thermometer according to the classifications in the following ways: 1. According to the main functions of the thermometer, with contact device can be divided into instructions and instructions ( Also called electric contact) ； 2. According to the environmental conditions of the thermometer, can be divided into ordinary, spray type, ship type, explosion-proof type ( Electric contact thermometer) ； 3. According to the connection position of the thermometer indicating device and measurement, can be divided into Angle ( The axial type) Type, straight ( The radial type) And adjustable Angle; 4. According to the principle of the contact device of the thermometer, can be divided into mechanical joint point, close to switch, induction; 5. According to the instructions of the thermometer device structure, can be divided into no order adjustment, with indicator; 6. Can be divided by thermometer connection installation, no fixtures, nipple, nipple, fixed external thread, card sets of connection, the fixed flange, movable flange.
