Pressure type thermometer when using and installation should pay attention to what time is it?

Pressure type thermometer by a temperature sensor, the pressure of capillary and bourdon tube pressure gauges. 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. Today we bring you know about the pressure type thermometer when using and installation should pay attention to the points. In the use, installation, attention should be paid to the following questions: 1. Gas or liquid filling pressure type thermometer meter reading is not only related to the temperature of the bulb, and the influence of the capillary tube and spring temperature, which is influenced by ambient temperature, while adopted a certain amount of compensation method, but also can't make fully compensate the influence of environment temperature, thus provides the scope when using the change of environmental temperature, actual use should pay attention to this problem. 2. Should not be measured close to the temperature of the room temperature, because the measured temperature near the room temperature fluctuations, capillary and spring tube steam evaporation, condensation, can not correctly and timely reflect the changes of temperature. 3. When using temperature measurement must not exceed the limit, once more than, bags all liquid vaporization temperature, then the vapor pressure of saturated vapor pressure is not, so relationship changed with the temperature response, measured results affirmation is not accurate, even due to the dramatic expansion of steam damage the instrument. 4. The capillary pressure type thermometer are prone to rupture and leakage, when installation should pay attention to don't lay in the easily damaged or worn, after selecting the appropriate position slightly taut, clamps, and protection Angle, corner is at right angles, capillary should not be high temperature heat source close to or contact with steam pipe, etc.
