Due to limitations in size and power dissipation, many prevalent measurement methods are incompatible with low temperature applications. Hall effect sensors have emerged as the superior option because of their compact size and low-power requirement. Until now, conventional Hall sensors have themselves been limited by material capabilities and the quantum Hall effect (QHE). Paragraf®’s Cryogenic Graphene Hall Sensors (GHS-C), however, enhance the ability of companies that make and/or use superconducting magnets to conduct continuous measurements in low temperature and high-field environments. This means ending the reliance on factory calibration or current-to-field measurements to evaluate these systems. With its patented graphene deposition process, Paragraf averts limitations by producing the GHS-C, which achieves operation in temperatures down to mK and field measurements of over 30 T.
