DAQ Unit

Developed especially for NVH measurement on electric motors powered by a frequency converter
Internal power supply during data acquisition makes the hardware extraordinary resistant against parasitic coupling
Up to 28 IEPE (ICP) Channels for standard accelerometer sensors, max sample rate: 51.2 kHz per channel
Up to 24 isolated analog inputs, max. sample rate: 51.2 kHz per channel
“Remote” connector (digital IO) for integrating the measuring device in an automated testing system
Designed for being operated both in a production environment, as well as any relevant applications in R&D
Lifetime free software for measurement and analysis

Use it on your computer, simultaneous display of time-domain signals, FFT and order-Spectrum
Made for electric motors: encoder input, speed and torque input, no extra “motor option” needed
Measurement function:
- Measure Back-EMF + motor zero-angle detection
- Coming soon: torque ripple measurement
- Stream to disk (up to 120 seconds)
Online calculation of power (Watt), reactive power (VAr) and apparent power (VA), phi and cos(phi)
Online calculation of DC power and mechanical power
“Snapshot” functionality – like you are used from an Oscilloscope
No complicated setup – all information are accessible with a single mouse-click
TCP/IP connection – no drivers needed, just use a computer with a LAN connector

Offer extreme resolution and accuracy: 24-bit A/D conversion and 64-bit integration on a signal processor allow a 6 digit display of the result
Measurement range covers pVs up to 1000 Vs with auto range function
Input amplification starts with divisor 64 (+/- 320V) and increases up to amplification 16384 (+/- 305 µV)
Accuracy of offset compensation is 30 ppt (part per trillion) of full range
Operate as standalone unit or connected to a PC via USB 2.0
Offers several fully automatic measurement procedures: Slide Mode, Rotor Mode, Helmholtz Coil Mode
