Abstract
A position sensor for monitoring the position of the valve element of a valve is described. The sensor comprises reflector means associated with the valve element and arranged to reflect energy, for example visible light, from a suitable source such that when the valve element is in a first position the reflected energy is incident upon a detector. Movement of the valve element away from the first position results in the reflected light no longer being incident upon the detector. The invention further relates to a valve including such a position sensor.
