OPB350L250

OPB350L250 is a OPB350 series tube liquid sensor. It is designed to work with 1/16inch, 1/8inch, 3/16inch and 1/4inch outside diameter clear tube. When output reference circuity is added, multiple output states such as "fluid present", "no fluid present" and "no tube present" can be recognized. Clear liquid present causes 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. If no tube is present, the phototransistor sinks current between the dark fluid and clear fluid states. Application includes non-contact fluid sensing, IV fluid, oils and other problem products, colored fluids.
