For the Monitoring of Liquids in Industrial Applications

The SONOCHECK air bubble detectors of type ABD06 detect air and gas bubbles in fluid-filled tubes and measurement chambers. These intelligent sensors can be used for the monitoring of fluids as well as for wet/dry alarm notifications.

The ABD06 has been specifically developed for industrial use. The contactless detection process allows the sensor to be used for applications that require hygienic and contamination-free conditions. The tube is simply inserted into the sensor and this enables a quick and uncomplicated changeover. The sensor automatically adapts to dynamically changing acoustic conditions. This guarantees a high degree of measurement stability despite fluctuations in the surrounding environment.

The SONOCHECK sensors have a user-specific programmable micro-controller with extendible functionalities, such as e.g. response time. The air bubble sensors can be adapted for individual tube sizes and other specifications, such as power supply, materials characteristics and signal output.

As an option we also offer a sensor version in a form suitable for use in areas with risk of explosion.

In addition to our standard sensors, we can also manufacture customer-specific solutions.
