Diagnostic units DUV and DUO
Diagnostic unit DUV
The DUV30A diagnostic unit evaluates vibration signals using frequency analysis
methods. A micromechanical acceleration sensor is used in the unit. Data can be re-
corded, processed and evaluated locally without any expert knowledge.
The DUV30A diagnostic unit is suitable for early recognition of rolling bearing damage
or imbalance. The continuous monitoring function represents a reliable and cost-effec-
tive solution compared to intermittent methods.
The DUV30A has been designed as a combined sensor that can be used as normal-
speed unit or slow-speed unit. The only difference is the measuring time in the firm-
ware and the resulting frequency range.
The following figure depicts the diagnostic unit DUV30A:
