Pressure type thermometer pictures

You know the pressure type thermometer? A reference picture? Below small make up to introduce pressure type thermometer for you. The principle of pressure type thermometer is based on the sealing temperature measuring system of liquid evaporation changes in the relationship between saturated vapor pressure and temperature, the temperature measurement. Pressure type thermometer bulb: it is direct with contact to feel the temperature change of measured medium components, so it has high strength, small expansion coefficient, high thermal conductivity and corrosion resistance and other properties. According to the working material and filling of different measured medium, temperature, package can be produced from copper alloy, steel or stainless steel. Capillary pressure type thermometer: it is made of materials such as copper or steel cold pulling into seamless tube, used to pass the pressure change. Pressure type thermometer is widely used in machinery, textile, chemical, pharmaceutical, food industry for the temperature measurement and control in the process of production. By the consistent high praise.
