A&D-Dependable Production Line Partner (Model:AD-3552)

To meet the demands of rapid change in the factory automation industry, A&D offers a powerful field tool with a new high level of performance.

The AD-3552 was created with a comparator function for machinery vibration & noise testing for production.

The AD-3552 FFT Comparator provides noise and vibration analysis that instantaneously delivers judgments "OK" or "NG"(no-good)for product testing of bearings, motors, etc.

Features

Compact, lightweight 1×1.4DIN enclosure easily mounted into rack. Dedicated for comparator, easy to handle. Compatible to Ethernet. Central control by a personal computer. Effortless operations through touch panel interface. With the utility software(provided free), files can be transferred between a PC and the AD-3552 FFT Comparators through Ethernet.

Powerful Analysis Software

When a single AD3551 FFT comparator is in use, a setup wizard allows easy setting of conditions. A setup wizard allows easy setting of conditions. The AD-3552 FFT Comparator has a built-in PC that features superior reliability and fast response. Setting judgment parameters for level, partial overall, octave band, total overall is practicable. (Block: 20 types, Shape: 1 type, Total overall: 1 type) Judgments under complex conditions can be delivered by combining comparator logic (AND, OR, NOT) Using a DI/DO board, the AD-3552 FFT Comparator can output judgment results and be controlled externally.
