You know the pressure type thermometer when using the matters needing attention

Pressure type thermometer mainly used in refrigeration equipment, Marine machinery. This kind of products usually use cycle is long, the precision requirement of the pressure type thermometer are relatively high, in addition to buying the right product, in the process of daily use correct use, reduce the error of temperature measurement is also important. We summarized the correct use of pressure type thermometer article 5 of the note. 1. Using pressure type thermometer inserted depth of the thermometer, is must be all bulb into 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. Using pressure type temperature time pay attention to the bulb can not exceed the prescribed upper limit of temperature measurement.
