OPB350 Description
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.
OPB350 Key Features
- Can identify if liquid is present in clear tubes that have an outside
- Opaque plastic housing enhances ambient light rejection
- Printed circuit board mounting or 24” (610 mm) 26 AWG wires
