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 ( Green LED), that the
device could not be calibrated ( Red LED) and when the analog output has reached the logical trip higher than the
calibration point ( Blue LED) or lower than the calibration point ( Green LED). The internal phototransistor load
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.
