Sensor apparatus
First Claim
1. Sensor apparatus for the non-contact monitoring of a predetermined end position of a movable mechanical element comprising:
- a probe operable to sample a distance between the probe and a target surface on the mechanical element;
an electronic measurement means which is connected to the probe and so constructed that in response to at least one control signal it generates a measurement signal corresponding to the distance; and
a control means connected to the electronic measurement means operable to generate the control signal, to receive the measurement signal and to generate an indicator signal to indicate that the predetermined end position has been detected,wherein the electronic measurement means is so constructed that the measurement signal is generated by the electronic measurement means at a time interval following receipt of the at least one control signal.

Abstract
A sensor apparatus for the non-contact monitoring of a predetermined end position of a mechanical element, in particular a door in an aircraft, is provided which comprises a probe, an electronic measurement means, and a control means. The probe is attached to the aircraft and samples the distance between itself and a target surface on the element to be monitored. The electronic measurement means is connected to the probe and is so constructed that in response to at least one control signal it generates a measurement signal corresponding to the distance. The control means is connected to the electronic measurement means and generates the control signals, receives measurement signals and generates an indicator signal to indicate that the end position has been detected.
