Abstract
1/f noise was measured for LakeShore RX-202A resistance temperature sensor. Its intensity increases significantly when the temperature is lowered below a few kelvin. It is shown that this rise in the noise intensity leads to the decrease in the temperature measurement resolution. For the lowest temperatures it is limited to 0.01 % only. A source of such large noise is the resistive layer of the sensor. To prove it, multi-terminal lab-made RuO2 + glass thick film samples were prepared and measurements, that allow discrimination between contact and bulk components of the sensor noise, were made.
