Abstract: The parallel and perpendicular magnetic field behaviour of five industrial grade platinum resistance thermometers (Pt 500) has been investigated. Measurements on the sensors were performed at various temperatures between 300 K and 4.2 K in the presence of intense static magnetic fields up to 9 T. The sensor performances were studied for perpendicular and parallel magnetic field. The field dependent temperature errors (DT/T) and the relative magneto resistance changes   (DR/R) are tabulated as a function of field and the temperature.

 

Keywords: Platinum resistance thermometers, Magnetic field, Cryogenic temperature, Measurements
