The LGP Vibra Align 2C/4C Plus All IN ONE ! is full option device!

Data Collector + Balancing + Alignment + Bearing Tester !

Laser Shaft Alignment System is a device that can measure and correct the misalignment of shafts, couplings, and pulleys in industrial machines. It uses wireless transducers with built-in rechargeable batteries and large 30mm CCD detectors to detect the angular and offset errors between the rotating elements. It also has electronic inclinometers that allow for convenient measurement in any shaft position. The device has a display control unit with a touch screen and a camera function that can show the alignment results and generate PDF reports. The device can perform horizontal and vertical machine alignment, Cardan shaft alignment, and other options. The device has a high accuracy, a long operating time, and a low cost compared to other laser alignment systems.

Overview on Rolling Bearing Condition Monitoring

Ideally, rolling bearing elements are separated by a protective lubricant film, which impedes their collision. However, manufacturing defects, damages, which appear during operation, dirt in the bearing, insufficient or incorrect lubrication – all these factors cause the collision of the bearing elements and, as a result, acoustic oscillations of a wide spectrum are generated in the bearing body.

A specially designed transducer (patent №18652) is used to filter out the part of this spectrum that carries information on the bearing faults detection. The transducer filters those acoustic oscillations which are generated by the bearing defects, and converts them into electronic signal proportional to the magnitude of shock pulse signal, that is amplified and measured by the BT-77 electronic unit in the relative units of decibels (dB).

A real new bearing is just from the beginning of its use, a source of induced vibration, the amplitude of the shock pulse of which is dBi.
