SEW-Eurodrive DUV30A vibration analysis sensor.

SEW-Eurodrive has launched its updated vibration analysis sensor, the DUV30A. Replacing the company’s DUV10A sensor, the DUV30A features faster sampling time at a constant speed, allowing the monitoring of more dynamic gear-unit applications.

It is designed to permit the early detection of gear-unit wear and damage, enabling site personnel to plan gear-unit maintenance. Housed in a compact body and closely mounted onto a gear unit, the sensor employs both fast Fourier transform (FFT) and high-frequency FFT (HFFT) harmonic signal evaluation to monitor gear-unit and bearing condition and vibration.

The sensor has been designed to detect abnormal frequencies across a range of 1.875 to 6000 Hz. Its sampling time of 0.8 s per monitored object means it can accommodate more dynamic gear-unit applications.

The sensor is equipped with an RS232 port for in-field parameter set-up and interrogation, and also features a second I/O port that accommodates speed input and alarm output connectivity to supervisory PLCs.

For sensor configuration and calibration the DUV-S software provides access to a comprehensive selection of diagnostic and performance data, and is downward compatible, accommodating both DUV10A and DUV30A units.

System diagnosis is further aided by the DUV30A’s integrated ‘green-yellow-red’ LED indicator. This provides on-site personnel with a ‘quick check’ option to establish the status of the gear-unit internals.
