SEW-Eurodrive DUV30A vibration analysis sensor

The DUV30A vibration analysis sensor replaces the DUV10A, providing faster sampling times at a constant speed and allowing the monitoring of more dynamic gear-unit applications. It enables gear-unit maintenance planning, as the sensor allows the early detection of roller bearing and gearing wear and damage, as well as gear-unit unbalance and resonance detection.

It has been designed to detect abnormal frequencies across a range of 1.875 to 6000 Hz, with a sampling time of 0.8 seconds per monitored object.

With a compact body and closely mounted onto a gear unit, it employs both FFT and high-frequency FFT harmonic signal evaluation to monitor gear unit and bearing condition and vibration.

The sensor is equipped with an RS232 port for in-field parameter set-up and interrogation, and a second I/O port that accommodates speed input and alarm output connectivity to supervisory PLCs. It can be configured to warn of abnormal gear unit or bearing condition once a pre-determined vibration alarm point has been reached and the alarm can be monitored via a supervisory PLC, HMI, SCADA or PC.

Required for sensor configuration and calibration, the software supplied also provides access to a selection of diagnostic and performance data.

The integrated green-yellow-red LED indicator provides a ‘quick check’ option to establish the status of the gear-unit internals.
