Auto Calibration Sensor Monitors Fluid/Air in Medical Tubing
Tue, 04/06/2010 - 5:08am
Providing medical design engineers with a cost-effective alternative to ultrasonic sensors, the OCB350 fluid sensor features automatic calibration circuitry, and is available with multiple output states, including "fluid present," "no fluid present," and "no tube present." The sensor is ideal for medical applications including monitoring fluid or air presence in tubing for infusion and transfusion pumps where fluids of different optical densities are used. The sensors are designed to maintain the calibrated setting even if power is lost. Once calibrated, the setting will remain constant, allowing for faster start up. Designers can initiate the calibration procedure at any time by grounding the J1-pin-4.
