Whether screws, pills or liquids – our sensors detect small parts regardless of the material. We offer precise special solutions for detecting bulk material, liquids, metals, plastics or air bubbles.
Ensuring that dosing has completed before moving to the next row of wells in a microplate is extremely critical to prevent possible cross contamination. Detection of individual drops from pipettes is possible with Balluff's line of MICROmote micro-optic photoelectric sensors. These sensors can detect a drop of liquid regardless of liquid type or color. Sensing heads are available with beam widths to detect drops within a defined area. In addition, MICROmote light band sensors are available when the defined drop orientation is unknown. The remote amplifiers provide easy setup to teach the sensor to detect liquid droplets.
Bubble or air-in-line detection is a challenge for lab automation that is easily solved with Balluff's cutting edge technology in micro-optic photoelectric MICROmote sensors. In this type of application it is critical to know whether or not liquid is flowing to ensure safe and proper function in liquid handling processes. Factors that need to be taken into account include tube diameters, tube transparency, types of liquids, and liquid transparency. Balluff's bubble detection sensors were developed with high precision optical components that create a uniform pin-point light distribution through the tube.
Detection of micro-bubbles or free-floating bubbles is critical in lab automation processes. Balluff's micro-optic MICROmote sensors utilize patented technology to solve these difficult applications. These sensors can detect bubbles smaller than the tubes inner diameter, smaller than 10 µm in diameter in capillary tubes, bubbles that are smaller than the human eye can see. The sensor can detect micro-bubbles as they enter a uniform illumination created by a concentrated arrangement of multiple light beams. Couple these sensing heads with remote amplifiers with multiple output options and easy setup to form a reliable detection sensor.
Accurate pill detection is a must in automated tablet counting and filling machines. Balluff's customization capabilities can provide customer specific solutions with a modular configuration of transmitters and receivers. The patented MICROmote technology enables lighting configurations to detect a wide variety of tablet sizes.
