Abstract
A contact sensor for very precise calipering of workpieces. The sensor has a force generating mechanism with two oppositely acting elastic members (64, 66) connected to one part (34) of the suspension device of a feeler (42) and deformable in the direction of movement of the feeler. An assembly carried by another part (36) of the suspension device includes an abutment (82), two mobile elements (72, 74) acting reciprocally on the two elastic members, and a spring (78) permanently biasing the mobile elements against the abutment from opposite directions. When the feeler is in a rest position, the two elastic members are pre-stressed by the mobile elements so that both elastic members remain under tension as long as movement of the feeler is confined to a calipering zone.
