Abstract
A digital readout and display adapted for use with a tank of oxygen under pressure provides pressure regulation, discerning of the pressure in the tank and consumption of the oxygen. A small battery within a case member powers this display. The readout device includes a gauge with a movable element responsive to pressure. An S-shaped rod is carried by and fixed to this shaft. This rod is very light in weight and in a secured condition is free at both ends to prevent friction of moving parts. The discharge end of this light-conducting rod comes in way of a light receiver carried by the body of the gauge. There is a multiplicity of receivers arrayed in a circular pattern near the edge of the gauge body and the light from this rod actuates a reed switch which sends an electrical signal to a microprocessor thence to an LED digital display. A single emitter may be used to send light through three rods each of which is carried by a gauge-type device.
