There are many factors that affect the final measurement results of temperature transmitters during their use. Today, we will analyze in detail the main factors that affect the measurement results of temperature transmitters.
The impact of interference——
There are various interferences in the actual working site of temperature transmitters. Temperature transmitters have certain anti-interference capabilities, mainly including radio frequency interference, electrostatic interference, external magnetic field interference, pulse interference, etc. Users can choose temperature transmitters with strong anti-interference ability based on their own usage site.
The impact of environmental temperature——
The impact of changes in ambient temperature on temperature transmitters is also known as temperature drift or simply temperature drift. This technical parameter is very important. Within the normal temperature range, the percentage of output change to the range is specified for every 10 ℃ change in ambient temperature, and generally does not exceed half of the basic error of the table.
Grounding impact——
When using temperature transmitters, they must be effectively grounded. Many damage to temperature transmitters or other instruments is caused by a lack of effective grounding, which can have a serious impact on the output signal of the temperature transmitter. Even directly causing damage to the temperature transmitter.
