1Α. Condition monitoring on rotating equipment

Condition monitoring on rotating equipment, by means of vibration analysis technic, for diagnosis of possible

upcoming defects, for applications which demand simultaneous acquisition from several measurement points

(channels).

Efficient and suitable choice for applications:

With variable operating conditions. (example: wind turbines, inverter electric motors, etc.).

With access difficulty during machine operation.

Multiple measurement points with simultaneous acquisition (up to 16 measurement points).

Use of several different kind of sensors (accelerometers, laser tachometers).

Device can be held on the field for as long as it is necessary so as to complete measurement acquisition

during different production stages.

Remote management to the device.
