ShareSummary
A thin wire platinum resistance thermometer with isotropic magnetoresistance is developed by adjusting the pitch angle in the winding of the sensing wire to a specified "magic" angle. The anisotropy between 20 and 70 K under magnetic fields of up to 8 T is smaller than 1%, compared with 35% for typical commercially available platinum resistance thermometers. A correction function with three temperature-independent fitting parameters is determined for the present sensors with an accuracy of 60 milliK between 20 and 100 K under magnetic fields of up to 8 T.
