An inclinometer device (3) comprises a) a pendulum (7) provided with means (15, 11) for emitting light from the pendulum; e) a plurality of spaced, relatively fixed light detecting elements (17) which are arranged and so related to the light emitted from the light outlet of the pendulum that for a given inclination of the device a particular one or arrangement of adjacent light detecting elements (17) is illuminated by light from the pendulum (7); f) means for determining the inclination of the device from the light detecting element or elements illuminated by light from the pendulum; and g) indicator means providing a representation of the determined inclination of the device. |
