Abstract
Use is made of thermoplastic materials in layered configurations as a thermally stable, rigid but not brittle strip of lengths of six inches to ten feet or more. The layered strip contains layers of conductive fibers in a resin matrix, which, through use of appropriate contact mechanisms and wiring, provide an assembly with an infinite potentiometer scale. The strips are especially useful in linear positioning indicators such as pneumatic and hydraulic cylinder and liquid level gauges. The strips are conductively connected by cutting a bias surface relative to said strips and placing resin thereon.
