All stainless steel bimetal thermometer has good performance and is gradually being widely used. Like other thermometers, it also has its own working principle. Today, I would like to introduce the working principle of stainless steel bimetal thermometer. Let's have a look with Xiaobian.


The pressure type thermometer uses the volume expansion or pressure change of liquid, gas or saturated vapor in a closed container as the measuring signal, The pressure type temperature measurement system is still widely used in the local indication and control of temperature. The advantages of the pressure type thermometer are simple structure, high mechanical strength, no fear of vibration, low price, no need of external energy. The sealing system of the instrument must be replaced, The installation accuracy is relatively low and easy to install. The transmission distance of capillary tube is limited. The working range of pressure thermometer should be within the measuring range, and the display meter and the thermometer should be in horizontal position as far as possible


The above content is the use principle of the pressure all stainless steel bimetal thermometer, we need to pay attention to the installation of the temperature bag installation bolts will make the temperature loss and lead to inaccurate temperature, installation should be carried out insulation treatment, and try to make the temperature bulb work in no vibration environment. More wonderful content, please continue to pay attention to our website.
