Electrical capacitance instrument and manufacturing method of the same |
摘要 |
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.
