| 摘要 |
A gauge for checking linear dimensions of mechanical pieces, comprising a differential transformer transducer including a first member, substantially cylindrical, which supports a core, a second member, substantially cylindrical, which houses electric windings, and a sealing bellows having its ends fixed to the first and the second member, respectively. The two members are mutually movable and the electric windings provide a measurement signal representative of the position of the core with respect to the second member. The ends of the bellows are coupled to annular seats defined in the first and the second members, with a coupling which generates substantially compressive stresses at said ends.
