MAGPy V1.0 Released – In Situ Compliance <10 MHz » SPEAG, Schmid & Partner Engineering AG
Summary
It integrates 27 miniaturized time-domain sensors and is far superior to any other instrument available on the market as it reduces the exposure overestimation by up to >40 dB. SPEAG provides high-precision measurement solutions for exposure evaluation and compliance testing where traditional instruments are not good enough and prevent innovations. Until now, it was impossible to carry out reliable in situ compliance testing in the close near field of wireless power transfer (WPT) systems or near high-current industrial installations – in these cases, the reference limits are exceeded by several factors but the systems are still compliant with the relevant safety regulations as the induced fields are much below the limits defined by the basic restrictions. To provide a solution to this problem, we have spent the last few years developing the Magnetic Amplitude and Gradient Probe System (MAGPy) for in situ compliance evaluations of WPT systems and any other strong magnetic near-field sources operating at frequencies of between 3 kHz and 10 MHz with respect to reference levels and basic restrictions. MAGPy V1.0 is the only handheld instrument for precise measurements in the near field of sources: • Its H-field sensor has an active area of only 1 cm2 as required by IEC PAS 63184:2021 for precise measurements (the smallest sensor on the market) • It is the only device able to estimate: • the maximum induced E-field averaged over a line of 5 mm (e.g., IEEE 2019) • It reduces overestimation of the exposure values of up to 40 dB (a factor of 100 for E-field/current density and a factor of 10’000 for SAR) • It allows entire recorded measurement sessions to be replayed, including post-measurement analysis and evaluations MAGPy V1.0 is optimized for in situ exposure and compliance evaluations at any location, including: • Ubiquitous devices equipped with WPT technologies (e.g., mobile phones, implantable medical devices, wearable devices, and Internet of Things (IoT)) To receive a quotation, and for further information, please contact us at info@speag.swiss or any of our sales channels.
