Abstract
A visual indicating device having an elongated slide valve mounted for longitudinal movement in a central bore of a housing. One end of the slide valve has a piston thereon mounted in a piston chamber and is responsive to a sensed fluid pressure in a flow line. The visual indicator is adjacent the other end of the slide valve and includes an outer fixed indicator element and an inner axially aligned rotatable indicator element. The outer fixed indicator element has a plurality of pie-shaped segments with alternate segments being transparent to permit visual viewing of the movable inner indicator element. The inner indicator element has a plurality of pie-shaped segments with alternate segments being of a green color and intervening segments being of a red or contrasting color. The altenate segments of the inner indicator element are axially aligned with the transparent segments of the outer indicator element in one position to present visually one color and the intervening segments are axially aligned with the transparent segments in the otherposition to present visually the contrasting color.
