Sensors for Foam Detection
Non-Contact Foam Detection for Demanding Processes – Precise, Hygienic, Space-saving
With its QCRC sensors based on corTEC® technology, EBE sensors + motion now offers a solution for foam detection and foam monitoring without the need to intervene in the medium. The sensors work through closed vessel and hose walls and reliably distinguish between air, foam, and liquid—completely contact-free and therefore ideal for sensitive and hygienic processes.
Foam Monitoring as a Critical Factor
In many industrial and scientific applications, foam acts as a process disruptor. This is particularly evident in:
- Fully automated lab workstations
- Bioreactors and fermenters
- Densely packed systems with complex sensor technology
Especially in the area of the reactor cover or narrow assemblies, every millimeter of installation space is often at a premium. Additional immersion probes or mechanical components exacerbate this problem.
At the same time, strict hygiene standards apply:
Every component that comes into contact with the medium increases the risk of contamination, makes cleaning more difficult, and causes costly downtime in the event of foaming. Non-contact sensors for foam detection completely avoid these disadvantages.
Technology: Precise measurements through capacitive and conductive detection
The sensors in the QCRC series continuously monitor the media condition in the process. Parallel measurement of capacitive and conductive parameters produces a robust measurement signal that reliably distinguishes between:
- Air
- Foam
- Liquids
- even Powdery Media
distinguishes itself – even under changing environmental conditions or in dynamic process control.
This allows foam formation to be detected at an early stage, overflow or process errors to be avoided, and fill levels and media changes to be reliably monitored. This combination makes corTEC technology one of the most versatile solutions for foam detection and non-contact foam monitoring in laboratories, pharmaceuticals, bioprocess technology, and industrial automation.
EBE offers an evaluation kit that allows you to test the sensor technology directly in the application and check whether the medium is detected reliably. Please contact us to order an Evaluation Kit.

Compact Design – Flexible Integration
The complete sensor core is integrated into the module. Measuring just 30 × 30 mm (1.18 x 1.18 in), the sensor is particularly suitable for applications with minimal installation space. The I²C interface provides immediately usable measurement values after installation and facilitates integration into existing systems. For development environments, EBE offers an evaluation kit that enables quick commissioning. This allows engineers to test the technology directly and verify its suitability for specific processes.
Next-generation Foam Detection
The QCRC series is designed for anyone looking for reliable, contactless, and hygienic foam detection—without compromising on precision, speed, or installation flexibility. Whether in laboratory robotics, bioreactors, or industrial processes, these sensors offer a robust solution for modern plant architectures where every centimeter counts.
