DEWETRON is an Austrian manufacturer of high-precision test & measurement systems. Their hardware and software solution is modular and intuitive to use. Thus, complex measurement tasks are simplified and recorded synchronously.
Mixed Signal Power Analyzer
DEWETRONs DEWE3-PA8 Mixed Signal Power Analyzer is the ultimate solution for precise power analysis, delivering a consistently low measurement error of just 0.03%. The Power Analyzer ensures the highest accuracy — even when operating at low range utilization.
The DEWE3-PA8 provides up to 16 power channels within a single chassis. With the intuitive OXYGEN software, a 11.6” touch display, and interchangeable TRION measurement modules, it can be easily configured for any measurement setup. Up to eight current transducers can be redundantly powered through the Power Analyzer.
The in-house OXYGEN software transmits both raw data (current/voltage) and the calculated e-Power parameters to the PAK live.hub, where they are combined with the NVH data.
A QUESTION FOR OUR PARTNER: WHAT CONVINCED YOU ABOUT THE PAK LIVE.HUB AND THE ECOSYSTEM?
"DEWETRON's partnership with Müller-BBM VAS results in a fully integrated, networked complete solution that more than meets today's requirements.
DEWETRON's Power Analyzer and the PAK live.hub from Müller-BBM VAS build the combined tool for the holistic analysis of electric motors, drive systems and complete vehicles. The synergy of precise measurement hardware, high-performance power calculation and forward-looking, sustainable solutions for dynamic data analysis is the key to even more efficient product development for our joint customers."
Use Case: Noise and vibration analysis (NVH)
For measuring vibrations and noise, three components are essential: Sensors to capture the signals (including pressure, sound, acceleration, or vibration sensors), a data acquisition system to record the sensor data, and an analysis system to process and interpret it.
Due to the many influencing factors in NVH analysis, it is crucial that all three components operate precisely and reliably. To ensure this, DEWETRON has entered into a cooperation with Müller-BBM VibroAkustik Systeme, offering a fully integrated turnkey solution that combines e-NVH and e-Power measurements.
DEWETRON Power Analyzers are connected to the data stream of NVH systems via the PAK live.hub. The measurement data is available in real time and fully time-synchronized. This allows electrical quantities as well as power and efficiency values of e-motors to be directly correlated with NVH data such as housing vibrations and emitted noise.
