How it works
New patented technology
PARALIGN uses ring laser gyroscopes in an inertial measurement system that quickly and accurately measures vertical and horizontal roll alignment and compares results against a benchmark standard. Ring laser gyroscope technology was first developed for aerospace guidance, navigation and control systems.

| How it's done - step by step |
PARALIGN contains three perpendicularly arranged, highly-precise ringlaser gyroscopes as used in aircraft and spacecraft. Just like a spinning top, the ringlaser gyroscopes have an inherent inertia, i.e. they tend to resist any attempt to change the orientation of the rotational axis in space for a certain length of time. If PARALIGN is then placed on the reference roll, it first “learns“ its position in space and then compares this with the changes in direction that result when it is moved onto the roll to be measured. The deviations are measured and converted into correction values. |
| In order to determine whether several rolls are positioned parallel to each other, PARALIGN is first placed on the „reference roll“and zeroed by pressing the button. The measurement system is then simply placed on the roll to be measured and –after a few seconds– the deviation from the reference roll can be read – simultaneously displayed as the main degrees of freedom of a roll: pitch and yaw. The third roll is then measured, etc. |
