Abstract

Existing measurement facilities do not allow the characterization of magnetic sensors at the operational temperatures encountered in a range of industrial applications. Routine calibration of such sensors can be carried out by various facilities, but are limited to ambient laboratory temperatures only. The National Physical Laboratory (NPL) has developed measurement facilities for the characterization of these sensors over a temperature range of -55 °C to +125 °C reflecting the actual temperatures experienced during their operation. This paper will describe the development of the traceable measurement systems at NPL that enables this characterization and will present results for fluxgate and AMR type sensors.
