OCB350 Overview
When output reference circuitry is added, multiple output states such as “fluid present,” “no fluid present” and “no tube present” can be recognized. Clear liquid present causes the phototransistor to sink the maximum current, while dark liquid present causes it to sink the minimum current. As bubbles pass through the tube, the signal will vary between the “liquid present” and “no liquid” states.
