Auto calibration sensor monitors presence of fluid, air in medical tubing

TT ELECTRONICS OPTEK Technology OCB350 fluid sensor provides automatic calibration circuitry and is available with multiple output states including ‘fluid present,’ ‘no fluid present,’ and ‘no tube present.’ Device maintains the calibrated setting even if power is lost. Once calibrated, the setting will remain constant, allowing for faster start up. The self-calibration feature allows the sensor to easily adapt to changes in fluid type, outperforming more expensive ultrasonic sensors.
