How to use the pressure type thermometer longer?

Pressure type thermometer mainly used in refrigeration equipment, Marine machinery, this kind of products usually use cycle is long, and is relatively easy for you to change, so we all hope that it can use cycle longer. So how can you use pressure type thermometer longer? We all know, in order to ensure the accuracy of the temperature, pressure type thermometer need verification on a regular basis. If our verification cycle and replace pressure type thermometer cycle is the same, we can reduce downtime losses at a time. Can let pressure type thermometer in verification cycle is not out of order, in addition to buying the right products, in the process of daily use proper use and maintenance is particularly important. We summarized five matters needing attention of using pressure type thermometer. 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. 5. Using pressure type temperature time pay attention to the bulb can not exceed the prescribed upper limit of temperature measurement. If you do the above 5 points, it can be to a great extent, use pressure type thermometer longer.
