Beware of high temperature failure instruments and meters are also difficult to survive the hot summer

[ Focus on Chemical Machinery Equipment Network ] Just after the summer solstice, will the dog days be far away? Dog days generally appear between Xiaoshu and Chushu, and are the hottest, humid and sweltering days of the year
.
After entering the fall, summer evil will cause frequent occurrences of “sauna days” with high temperature, high heat, and high humidity.
This not only has a certain impact on human health , but it is also very prone to malfunctions for many outdoor instruments
.
So, how does the instrumentation pass the dog days smoothly?
 

The temperature is too high in the three-volt weather.
After a long period of exposure, the surface of some outdoor instruments and meters will become hot.
While ensuring that the housing and wiring of these instruments and meters are not deformed by the high temperature, pay attention to the excessive temperature.
Whether the high will react with the surrounding medium and cause a fire
.
In order to reduce the occurrence of such incidents, it must be on-site real-time detection, the use of advanced and reliable security tester table, to avoid the accident, in order to ensure safe operation
.

 

In fact, many instruments and meters have very strict requirements for the temperature and humidity of the environment, and they must meet the corresponding temperature and humidity to work normally
.
Higher or lower temperature will cause distortion of most precision instruments, which will affect the accuracy of the test and the life of electronic components
.
For example, the inverter must pay attention to heat dissipation in summer, otherwise the field tube will be easily burned; for scanning electron microscopes, overheating of the instrument will cause noise in the image; overheating of the X-ray energy spectrometer will cause abnormal counting rate, etc.

.
Therefore, in the summer of high temperature, humidity, and temperature change, the staff are obliged to increase inspection and testing of instruments and meters to ensure the normal operation of instruments and meters, and to ensure the safety of production
.

 

In addition to the environmental characteristics of high temperature and high humidity in the dog days, there are many other things that instruments and meters should pay attention to.
Maintenance personnel should also take targeted measures according to the characteristics of the instruments and meters themselves
.
For example, for some small outdoor precision instruments and meters, direct contact with human hands should be avoided during operation, which may cause burns.
Therefore, it is recommended that operators wear gloves to avoid direct contact with the instruments
.

 

　　In addition, instruments and meters should also be cleaned and maintained regularly
.
Since the instrument will accumulate a certain amount of dust after being used for a period of time, it is best to let a professional maintenance engineer or under the guidance of the instrument to carry out the internal dust removal and cleaning of the instrument, and do some necessary monitoring, adjustment and recording , To prevent the instrument and meter from malfunctioning in high temperature weather
