RF Immunity at LM235

[AOrti]

I have an LM235 temperature sensor separated from the measuring device 5 meters.

When an RF is induced to the LM235, it measures wrong temperatures. I have tried to minimize the problem by putting capacitors on the sensor pins but I have not obtained any results.

Is there any way to reduce this problem?

schematic , rf power level and frequency ?

also have you tried wrapping a few turns of the cable around a hunk of Ferrite ..toroid or two hole balun style - a ferrite mix suitable for the RF frequency.
