Helwig Carbon Products, Inc. (Milwaukee, WI) has announced that the BPK-Probe has been issued US Patent #10942203 on March 9, 2021. This major innovation provides a means to detect induced shaft currents in motors controlled by VFD drives. This analysis will help identify the potential for bearing failures and avoid costly downtime. This patented technology will be valuable to the industry and contribute to preventative maintenance practices.
The BPK-Probe uses a proprietary algorithm to test for shaft voltage while displaying PASS/FAIL results and the risk on an LCD screen in 20 seconds or less. The test data is recorded on a micro-SD card for reporting. The testing device features a robust joystick design built for preventative maintenance technicians, vibration analysts, reliability engineers, and motor repair specialists. The handle includes a BNC output for connection with an oscilloscope for a more detailed analysis of shaft voltages.
