INFRA-RED REFLECTIVE AIR-IN-LINE SENSOR SYSTEMS

摘要

Air bubble sensor systems and methods of using the air bubble sensor systems are provided. In a general embodiment, the present disclosure provides a sensor system comprising a detection chamber (40) constructed and arranged for attaching to a tube, and an infra-red reflective sensor comprising an infra-red light emitter (32) and an infra-red phototransistor receiver (34). The infra-red reflective sensor and the infra-red phototransistor receiver are positioned at or near the detection chamber. The infra-red light emitter can be a light emitting diode.
