LASER LEVELLING INSTRUMENT WITH A LEVELLING BASE AND FINE SELF-LEVELLING OF THE LASER BEAM
摘要
A laser levelling instrument with a levelling base (7) and fine self-levelling of the laser beam (10) has an inner cylinder (5) which bears aligning elements and is suspended in an oscillating manner inside an outer cylinder (1). The laser levelling instrument is characterised in that the outer cylinder (1) and the inner cylinder (5) form a capacitor system with opposite electrode faces; the outer cylinder (1) is joined at right angles to the base (7) and is centred with respect to the beam axis (11); and signals for detecting the oscillating position of the inner cylinder (5) may be derived from the capacitor system.
