Tube Liquid Sensor OPB350 / OCB350 Series (Calibration Circuit Available) N C P ackage P ackage Features: Can identify if liquid is present in clear tubes that have an outside diameter of 1/16 1.6mm , 1/8 3.2mm , 3/16 4.8 mm or 1/4 6.3 mm Opaque plastic housing enhances ambient light rejection T Printed circuit board mounnti g or 24 (610 mm) 26 AWG wires Package 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 custome r will have to identify the typical current values for each situation. The ratio between the different states allows acknowledgement of dieff rent 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 eoff rt 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 calibraonti 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. For a custom PCBoard design for your unique challenge, contact your OPTEK representative.
