Abstract:
1. A sensor apparatus for detecting an overhanging load on a carrier device, comprising: a sensor arrangement with at least one transmitter, at least one receiver, and an electronic unit for controlling the transmitter and receiver, the electronic unit configured to: enable the at least one transmitter to emit a light barrier across a first region and across a second region, wherein the second region is separate from the first region, enable the at least one receiver to detect the light barrier transmitted across each of the first region and the second region, generate a first signal corresponding to an interruption of the light barrier in the first region, generate a second signal corresponding to an interruption of the light barrier in the second region, wherein the first region corresponds to the carrier device and the second region corresponds to the load, and compare the first and the second signals to ascertain whether the load is overhanging the carrier device.
