The architecture of the common industrial thermometer meter is introduced

Instrument is introduced the structure of the common industrial thermometer thermometer feel moved by your warm and cool, in life, we cannot leave it everywhere, as we all know, different places we use thermometer is different, especially industrial thermometer, bring us both a lot of convenience, but do you know the the structure of the thermometer? We have to spread the knowledge! It is formed by inductive temperature, medium temperature filling package, transmitting pressure components ( Capillary) And pressure sensitive components ( Spring tube) Of all metal components. Wen bags pack heat medium such as gas, liquid or liquid evaporation. When the temperature measured medium, put the bulb temperature of work material pressure caused by the temperature increase volume expansion. The pressure change the capillary is passed to the spring tube and make it produce certain deformation, and then with the help of a gear or lever transmission mechanism, such as drive the pointer rotation, points out the corresponding temperature. Thus it can be seen that bulb, capillary and bourdon tube when the three important component. It is the pressure type thermometer. The commonly used protection tube structure has two kinds: one kind is axial structure, bimetallic thermometer dial plane and protecting tube is vertical connections: another kind is the radial structure, bimetallic thermometer dial in horizontal plane and protection tube connection. Can be observed according to the operation conditions of the installation and convenient to choose the axial or radial structures. It can also be made with upper and lower limit contact electric contact thermometer, when the temperature reaches a certain value, closes the electric contact, can send electrical signals, realize the temperature control or alarm function. It is the bimetallic thermometer. To understand both the structure of the thermometer, can perceive the thermometer you mysterious lifted the changes in temperature? Oh thermometer actually have a lot of mystery, such as its principle, form,,,,,,, as long as you are a love of learning life everywhere find mysterious color!
