AD-101
Air Bubble Detector
Bubble detection is critical in applications such as infusion pumps,
hemodialysis and blood flow monitoring. TE Connectivity (TE) 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 ofOperating Parameters &Specifications

 Temperature range: 0°C - 40°C

positively identifying the presence of a break in flow of any type ofliquid.

 Response time: 0.2msFeatures Output: 3.3 V TTL Logic Tubing outer diameters of 4mm and 6mm standard (sensor can becustomized to tubing outer diameters between 3 and 10 mm)

 Input: 5VDC-24VDC

 Detects bubble size as small as 70% of tubing inner diameter 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 housingApplications

 Infusion Pump

 Apheresis/Auto-transfusion
 Biotech/DNA Analysis
 Blood Processing
 Immunoassay

 Hemodialysis

 IN-VIVO Detection of Gas
 Hydroponics

 Smart Farming Food Processing

 Chemical Analysis
