GMW is Exhibiting at EV Tech And Battery Show, September 11-13, Novi, MI

GMW will be exhibiting at the co-located Battery Show and Electric & Hybrid Vehicle Technology Show in Novi, MI, September 11-13. GMW will be in Booth 426.

Conference details are available at: and

A free exhibition-only pass is available from either link above.

GMW will be showing:

  • CPCO and CPC Clamp-on Current Probes featuring current ranges from ±250A to ±16000A and frequency response from dc to 75kHz (-3dB). The small size, light weight plus vibration and water resistance enables electrically isolated, long-term, sub-system current monitoring in test cells or vehicles, including long-duration, continuous testing at -30°C.
  • Clip-around, Rogowksi Coils AC Current Probes from Power Electronic Measurement (PEM), with Coil cross-section down to 1.6mm and Coil lengths to many meters with full-scale current ranges from 30A to 1MA. Newly available are probes with response to 50MHz (-3dB), making these Probes applicable to a wide range of isolated current measurement on switching device leads, on leads from VSD to motors and in resonant wireless charging coils. Also available from PEM are the CMC Common Mode Current Probes with a frequency response tailored to reject the nominal drive current frequencies but have high sensitivity in the high frequency common mode current region.
  • IPCT Zero-Flux DC Current Transducers from Bergoz Instrumentation have ranges from 10mA to 5A full-scale. The IPCT features a large 82mm (3.2”) aperture, dc to 4kHz frequency response and current resolution to 10uArms and can be used for dc or ac, differential or leakage current measurements on complete cables for ac-dc chargers, PV to dc battery storage, variable speed drive to motor assemblies. The very high stability and reproducibility of these Transducers enable applications to product development, production quality control or long-term condition monitoring.
  • DC/AC Current Transducers from Danisense, with very high resolution and accuracy, wide dynamic range with full-scale current ranges to 10kA and dc to 500kHz(-3dB) for charge-discharge measurements of batteries or motor drive efficiency measurements using power analyzers or high-resolution data loggers.

Our partners from AKM Semiconductor will be showing Low Noise, Coreless Hall-effect Current Sensor ICs, with the new CZ-37xx series featuring ranges from ±5A to ±180A and typical accuracy of ±0.5% (Ta 0 ~ 90°C) .Chris Baltar and Yuko Nishikawa from AKM will be exhibiting at the Asahi Kasei booth 2319.

For current instrument calibration, GMW is now ISO-17025 accredited from 40A to 8kA at both DC and 60Hz. Sandro Renteria, Calibration Manager at GMW, will be with Brian Richter at the GMW Booth. If you are attending, please stop by.
