One end of the capillary is connected to a temperature bulb, which is the temperature-sensing part of the meter, and the other end of the capillary is connected to the display part of the meter (for a remote thermometer), or the execution part (for a temperature switch). Take the remote measurement thermometer as an example to illustrate its working principle: the temperature bulb is filled with a medium (liquid or gas), and using the principle of medium thermal expansion, the pressure generated by the expansion of the medium is transmitted to the display part of the instrument through the capillary tube, and the display of the instrument The part is essentially the watch core of a pressure gauge, which makes the switch move according to the pressure generated by the medium at different temperatures.
