What kind of pressure type thermometer thermometer?

Pressure type thermometer is mainly used in refrigeration equipment, Marine machinery field, its working principle is based on the sealing temperature measurement system in evaporation of the liquid saturation change relationship between air pressure and temperature, and temperature measurement. When bulb feel temperature, saturated vapor produced the corresponding pressure in the closed system, cause the change of curvature elastic element, make its produce a shift in the free end, again by the displacement amplification mechanism of gear into the indicated value. Pressure type thermometer by dial, pointer, elastic element, the transmission mechanism, base and capillary, work material, bulb, etc. Substance can be gas or liquid. Chart below: thin capillary determines it is mainly used for remote temperature measurement, often used for Marine equipment or some tanks, is one of the common field indicating instrument. Use pressure type thermometer should pay attention to clean up and check, regularly test the measured values.
