TE Sensor Solutions Air Bubble Detector

Bubble detection is critical in applications such as infusion pumps, hemodialysis and blood flow monitoring. TE Sensor Solutions has developed a new compact AD-101 Air Bubble Detector (ABD) for non-invasive continuous monitoring of fluid for air bubble detection. Using ultrasonic technology, the AD-101 sensor is capable of positively identifying the presence of a break in flow of any type of liquid.

Features & Benefits

  • Detects bubble size as small as 70% of tubing inner diameter
  • Tubing outer diameters of 4mm and 6mm standard (sensor can be customized to tubing outer diameters between 3 and 10 mm)
  • Non-invasive design eliminates sterility and fluid compatibility concerns
  • High noise immunity to EMI/RFI
  • Acoustic coupling agent not required
  • Integral electronics
  • Power-on and continuous self-diagnostic tests to confirm functionality
  • LED indication of sensor wet and dry state visible through housing


  • Medical Electronics


Infusion Pump, apheresis/auto-transfusion, biotech/DNA analysis, blood processing, immunoassay, chemical analysis, hemodialysis, IN-VIVO detection of gas, hydroponics, smart farming, food processing
