PRODUCTION DATA
The long wire lengths of current loops invite radio frequency interference (RF). RF can be rectified by the input circuitry of the XTR11x or preceding circuitry. This RF generally appears as an unstable output current that varies with the position of loop supply or input wiring. Interference can also enter at the input pins. For integrated transmitter assemblies with short connection to the sensor, the interference more likely comes from the current-loop connections.
