Allen-Bradley is a same name associated with low temperature sensors, since a now obsolete line of carbon-composite resistors manufactured by Allen-Bradley show an approximately inversely proportional temperature dependence at low temperatures. This undesirable characteristic for commercial resistors (since an ideal resistor should have no temperature dependence) is suited for cryogenic measurement, which paradoxically has partly helped establish a name for Allen-Bradley among the lay electronic enthusiast. Allen-Bradley resistors are commercially available at a premium, often supplied with calibration data.
