Application: Sensing the position of loading ramp
Product: Position Transducer LWG
The London Eye was erected on the South Bank of the Thames to mark the new Millennium. One of the design criteria is that it had to be accessible by everybody included the disabled. In order to enable people in wheelchairs to enjoy a ride, access is by means of loading ramps, the positions of which need to be measured.
The LWG transducers are fixed to the loading ramps and measure their position. This information is one of the inputs to a closed loop servo system which adjusts the ramp position in order to compensate for expansion and contraction of the wheel. As the wheel is 135 metres in diameter and fabricated from steel the movement is quite significant.
