Temperature transmitters are used more and more extensively, and users will encounter inaccurate measurements during use, this article will take you to understand what factors affect the measurement results of temperature transmitters. Users can pay attention during use to avoid impact.

Effects of interference

In the real work site of the temperature transmitter there are all kinds of interference, the temperature transmitter has a certain anti-interference ability, mainly radio frequency interference, electrostatic interference, external magnetic field interference, pulse interference, etc. Users can choose a temperature transmitter with strong anti-interference according to their own use site.

The effect of ambient temperature

The effect of changes in ambient temperature on temperature transmitters is also called temperature drift or simply temperature drift. This technical parameter is very important, in the normal temperature use range, every 10 °C change in ambient temperature, the output change as a percentage of the range to specify, generally not more than half of the basic error of the table.

Grounding effects

When the temperature transmitter is used, it must be effectively grounded, and many temperature transmitters or other instruments are damaged because there is no effective grounding, which will have a serious impact on the temperature transmitter output signal. Even directly damage the temperature transmitter.
