Features:
Can identify if liquid is present in clear tubes that have an
outside diameter of 1/8" (3.2mm), 3/16" (4.8mm) or 1/4" (6.3mm)
Opaque plastic housing enhances ambient light rejection

Description:
The
OPB350
series liquid sensor is designed to work with 1/8” (3.2mm), 3/16” (4.8mm) and 1/4” (6.3mm) outside
diameter clear tubes. 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. If no liquid is present, the phototransistor sinks only a small amount of current. If no tube is
present, the phototransistor sinks a larger current than in the “no liquid” state.
Smaller outside diameter tubes can be used when the tube is sized up to one of the standard sizes and is fitted
properly in the housing opening. For example, fluid in a 1/16” (1.6mm) outside diameter tube can be sensed
when a piece of tubing with a 1/8” (3.2mm) outside diameter and a 1/16” (1.6mm) inside diameter is used as an
adapter.
