Do you know what are the technical parameters of bimetallic thermometer?

Bimetallic thermometer is a kind of suitable for the measurement of low temperature, the detection of industrial instrumentation. Can be used to directly measure the temperature of the gas, liquid and steam. It's working principle is to put the two pieces of expansion coefficient difference is very big pieces of metal welded together. When the temperature changes, the difference is very big, caused the different expansion coefficient of expansion and contraction, the deformation of sheet metal bending. According to different deformation and produce different momentum, momentum to drive the connection shaft and the other end of the indicating needle, indicate the temperature. Today we have a common technique parameters of bimetallic thermometer. Installation method: axial, radial, universal type three kind of types. Surface diameter: 60 mm, 80 mm, 100 mm precision, such as: grade 1, 1. 5 level measuring range: - 40+80℃，0- 100℃，0- 150℃，0- 200 ℃ connection mode: threaded connection or flange connection thread: M27 * 2, M16 * 1. 5 such as heat pipe material: SS304, SS316 heat pipe diameter: 6. 35 mm, 8 mm heat pipe length: 100 mm when measuring temperature protection tube should be below 100 mm long all measured medium, to keep temperature accuracy. Execution standard: JJG226 - 2001 'the bimetallic thermometer verification regulation'
