An electrical capacitance instrument achieving high-volume production and a manufacturing method for the same. In a slide caliper detecting a change of electrical capacitance upon a displacement value of the slider 10 in relation to the base scale 1 having the main scale 20 of the measuring standard, the improved slide caliper is structured by the main scale 20 defined by plural electrodes 21 printed on a surface of the base plate 22 made of an insulator film at predetermined intervals with electrically conductive ink, and the base scale 1 is made by injection molding using a material of engineering plastics on which the main scale 20 is applied securely, so that the slide caliper can be manufactured in large numbers.

Electrical capacitance instrument and manufacturing method of the same

A clamping assembly for attaching a probe device to an attachment arm of a measuring instrument which extends from the instrument along a first axis. The probe device has a base arm positioned adjacent to the attachment arm in an axially overlapping manner. The clamping assembly includes a first annular clamping member proximate the measuring instrument, a second annular clamping member positioned axially adjacent the first clamping member, a rotatable annular clamping ring encompassing the first and second clamping members, and an arrangement for offsetting a central bore of the second clamping member relative to a central bore of the first clamping member along an axis extending perpendicular to the first axis during a relative axial movement between the clamping ring and the first clamping member. The effect is to urge the base arm into abutment with the attachment arm in a direction along the second axis.
