The reason and countermeasures of the on-site digital jitter of the integrated temperature transmitter

The integrated temperature transmitter is a combination of a temperature sensor and a temperature transmitter. The temperature signal is converted into a two-wire 4~20mADC electrical signal and transmitted to a display, a regulator, a recorder, a DCS, etc. to achieve temperature ** **** Measurement and control. However, sometimes the integrated temperature transmitter with on-site display has a large and small change in the display value when it is displayed in the field. The reason may be that the integrated temperature transmitter is affected by the electromagnetic field at the scene, so that the above occurs. Question, how to solve it? The first step is to install the integrated temperature transmitter installation location away from the location with magnetic field interference or change its electrical converter to a fully isolated temperature transmitter.
