SONOCHECK ABD06 air bubble detector - The flagship sensor for industrial applications

Air bubble detection in industrial applications is highly relevant when talking about process stability and product quality. The SONOCHECK ABD06 air bubble sensors are widely used such as in filling, pipetting, dosing and mixing systems, painting facilities, in dispensing fats and oils and in gluing processes. In accordance with the robust design, the ultrasonic sensors particularly prove their strength with harsh industrial environments:

  • Non-invasive measurement method directly through the tubing wall
  • Suitable for hygienically critical applications | contamination resistance
  • Fitting for a wide range of plastic tubing types, e.g. PVC, PE, silicone, PUR | no limitations due to the use of opaque tubings
  • Applicable for water, water-like and low-viscosity liquids without / with few solid particles
  • To be used without special acoustic coupling precautions
  • Sensor adaptation to dynamically changing acoustic conditions
  • Optionally available with ATEX certification for use in hazardous areas

In addition to standard fluid monitoring processes used to detect air bubbles smaller than 1/3 of the tubing ID, the SONOCHECK ABD06 can also be utilized as a full/empty detector.

CE-certified air bubble detector featuring interfaces for industrial processes

  • Operation voltage: +12 to +30 VDC
  • PNP/PWM switching output
  • Serial interface / RS485
  • Optional analogue outputs: 0-10 VDC / 4-20 mA

SONOCHECK ABD06 air bubble sensors feature a user specific programmable microcontroller. This allows to adapt

  • the response speed of the sensor,
  • the power supply and signal outputs as well as
  • to individual tubing dimensions, among others.

Customer Reviews

Jeff Poland, President and CEO at Century HLM, on our air bubble sensors:

“We started with SONOTEC's ABD05 series sensor. After our research and interview process SONOTEC had the only sensor capable of meeting 60601 3rd edition specifications for a fail-safe free hanging non-intrusive arterial line air detector sensor.” [Read more]

Jochen Hübner, R&D and Quality Management Representative at Herrmann Apparatebau GmbH, on our Air Bubble Sensors:

“When searching for a suitable sensor our engineers came across SONOTEC. We chose the air bubble detector ABD06 of the SONOCHECK-series – in a customized version. The small size and the approved safety functions were the main reasons that spoke for the sensor.” [Read more]
