Description:

The OPB350 series liquid sensor is designed to work with 1/16” [1.6mm] 1/8” [3.2mm], 3/16” [4.8 mm] and

1/4” [6.3 mm] 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 tube is present, the phototransistor sinks current between the dark fluid and clear Fluid

states. The customer will have to identify the typical current values for each situation. The ratio between the

different states allows acknowledgement of different conditions.

The OPB350L series have leads that are designed to mount directly to PCBoards. The OPB350W series with 26

AWG wires are remote mountable. The OCB350 series provides a full solution with automatic calibration

capability and a preset trip level.

The OCB350 series is configured to optimize the design effort needed to use a fluid sensor with the addition of

self calibration circuitry. The OCB350 series are easy to use requiring only an optical device and power supply.

Four lights are provided on the board that acknowledge when the device is calibrated

device could not be calibrated

calibration point

resistance can be set for three different values (~2.5K, ~9.6K or ~27K Ohms). A Reset/Clear pin is provided for

remote signaling to calibrate of the system.

The OCB350 series comes with an OPB350L_ _ _Z, PCBoard, interface cable (OCB100-MC24) and all the

necessary electronics required for sensing either transmissive or opaque fluids.

See “Theory of Operation” for detailed information.
