Hangzhou bimetallic thermometer manufacturers instrument co. , LTD is the manufacturer of the thermometer, offers a variety of industrial use thermometer. Pressure type thermometer is a kind of industrial thermometer, about how it is temperature measurement, is a lot of people are concerned about a problem. Pressure type thermometer is the use of liquid or gas pressure or volume made of the characteristics of non-contact temperature sensor with temperature change. As a result of the change of pressure change in the curvature of spring tube, and the free end displacement, through the connecting rod and direct drive gear drive the pointer on the dial indicator temperature changes in the value.

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, 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. This is pressure type thermometer temperature measuring method. The article comes from baidu.
