Precision Tube Sensors provide microbubble detection.

Press Release Summary:

With uniform illumination of tube's liquid column, MICROmote® Optical Precision Tube Sensors can detect free-floating air bubbles smaller than 10 µm in diameter in transparent liquids. Uniform illumination is created by concentrated arrangement of multiple light beams, each with individual uniform intensity distribution, surrounding tube. When small air bubble enters sensing field, it induces significant signal jump on sensor's receiver elements, enabling reliable detection.

Balluff's New Precision Tube Sensors for Microbubble Detection

The Balluff microbubble detection sensor is used in special cases where free-floating, microbubbles need to be detected within a tube. This sensor uses patented technology to detect bubbles even smaller than 10µm in diameter -- bubbles smaller than the human eye can see.

Florence, KY – The new Balluff MICROmote® optical precision tube sensors are designed to detect free-floating air bubbles in transparent liquids. These free-floating air bubbles have dimensions smaller than their tube's inner diameter.

The sensor's ability to detect free-floating air bubbles results from a uniform illumination of the tube's liquid column. This uniform illumination is created by a concentrated arrangement of multiple light beams, each with an individual uniform intensity distribution, surrounding the tube. When a small air bubble enters the sensing field it induces a significant signal jump on the sensor's receiver elements. This signal jump enables reliable detection of the tiniest air bubbles, even microbubbles. (A microbubble is defined as a bubble smaller than one millimeter in diameter.)

Together with the microprocessor controlled MICROmote® amplifiers, with either switching or analog output, these tube sensors form a complete detection system with diverse application possibilities for laboratory, analysis and medical technology.
