How to correctly use inflatable pressure type thermometer?

Industrial pressure type thermometer by filling the medium is different, can be divided into gas pressure type thermometer, liquid pressure type thermometer and steam pressure type thermometer. Gas pressure type thermometer mainly used in refrigeration equipment, Marine machinery. For the product accuracy is high, in order to correctly use the gas pressure type thermometer, reduce the temperature measurement error, must do the following: 1. Thermometer inserting depth, use gas pressure type thermometer is all bulb must be permeated the measured medium. Otherwise, will bring in value error. 2. Using temperature time, spring and capillary environment temperature changes will affect the value for the thermometer, and therefore by filling in the spring tube and the capillary is heat medium, so the environment temperature and the degree is not at the same time, will cause a certain value for error, and this, inflatable biggest influence; Liquid type of times; The steam had no effect. Instrument the surrounding environment temperature shall not exceed 50 c. 3. Installation temperature time must pay attention to the spring tube and bulb at the same height as far as possible, otherwise the vapor and liquid pressure type thermometer will lead to the error value. Bulb is high value is larger than the actual value, low temperature package is smaller than the actual value, the value for the influence of gas pressure type thermometer is negligible. 4. Installation is must pay attention to protect the capillary, and may not be violently bent many times, shock or damage to the sealing, but also avoid the corrosion influence of capillary and spring. 5. Using gas pressure type temperature time pay attention to the bulb can not exceed the prescribed upper limit of temperature measurement. The correct use of gas pressure type thermometer, on the one hand, can increase the service life of the product, have the effect of cost savings. On the other hand can reduce the error in the measurement, thereby reducing the occurrence of equipment failure.
