<p>The eddy current measuring device has a housing (1) in which is mounted a shaft (3) carrying the customary multipole magnet (4). Cooperating with the magnet is an eddy current driven bell (5) having a closure ring (6) and a temperature compensating element (7) which are mounted on a measuring shaft (9) by means of a bush (8). The shaft runs in bearings (10, 11) on the end of the eddy current generator shaft and mounted in the housing. On the measuring shaft (9) is a further bush (23) to which is attached one end of a spiral spring (24). The other end of the spring is gripped between elastic fingers (26, 27) on an arm (28) of a ring-shaped holder (29). The holder is rotatably mounted on a bearing member (14) and is axially positioned by projections (30-2) thereon. An adjustment screw (41) releases a clamping member (36) and permits rotation of the spiral spring holder (29) for adjustment.</p> |
