No mechanical influences on the rotor during measurement
Determination of unbalance and rotor weight
Simple and low-cost rotor adapters
No drive system and no protection device required
Short measuring times
Powerful PC based CAB 920 measuring unit with TFT screen
2 versions available:
- Table-top version
- Enclosure-mounted version for large rotors

Special features

Direct display on achieving of tolerance limit, operator prompting during calibration process, memory for calibration data for easy change-over from one work-piece type to the next at the push of a button.

Compact design ensures optimum ease of deployment.

Program for compensating of adapter errors, test program displaying operator or system errors, process control through host computer is possible, integral product data base.

Design

Range of application

Measurement of the static unbalance of disc-shaped rotors such as unfired grinding discs, propellers and ventilators.

Unbalance correction by addition of material directly on the machine or by removal of material on separate correction units.

Can be used for mere unbalance measurement, for tasks in production involving unbalance correction, for incoming goods inspection, for re-balancing and for weight measurement.
