Description

Technical Field

[0001] The utility model belongs to the technical field of metal thermometers, in particular to a φ8 remote transmission bimetallic thermometer. Background Art

[0002] As a field display thermometer for measuring medium and low temperatures, it is usually used in conjunction with display instruments, recording instruments and electronic regulators. It can directly measure the temperature of liquid, steam and gas media in the range of 0 to 400°C in various production processes. The common process of the φ8 remote bimetallic thermometer is to use resistor hoisting, which is above the temperature sensing element. Because the two measuring ends are not at the same horizontal position, when the medium is not full, the resistance display temperature and the bimetallic temperature will be inconsistent, which affects the use of the field.
