Absolute positioning of the elevator car for travel heights up to 392 m.
The contactless absolute measuring system for shaft copying – also called shaft information or positioning system – has an extremely compact, very robust design. In addition to the sensor, which detects the position of the elevator car 100% slip-free, this also includes the right evaluation unit, the so-called Position Supervisor Unit, or PSU for short. With the Safe System, consisting of SIL3-certified sensor and matching evaluation unit, elevator and safety functions can be realized according to EN 81-20/21/50.
