Advanced Fluid Quality Sensors for Detecting Fluid Properties for OEM Applications
The corTEC® fluid quality sensors, QCRB, from EBE offer new possibilities for the precise measurement of fluid properties. These quality sensors have been specially developed for the detection and monitoring of fluids in OEM and process applications.
QCRB Sensors – Powerful Technology
The technology of the QCRB quality sensor for fluids enables both capacitive and conductive measurements for precise media detection. This dual measurement method allows a detailed analysis of the media and offers a high selectivity that could previously only be achieved by using multiple sensors. The corTEC® technology is a patented sensor principle that is able to determine the real and imaginary part of the permittivity. This makes it possible to differentiate between media based on different capacitance and/or resistance values, even if the relative permittivity or conductivity is identical.
Measurement Ranges and Accuracy
corTEC® capacitive measurement ranges from 0.1pF to 80pF with a resolution of typically less than 0.1pF. This allows detection of media in a relative permittivity (εr) range of vacuum (<=1) through oils and solids (typ. <5) all the way to water (80 and higher). The conductance measurement range is from 0,04 to 100mS (10 to 25.000 Ohm) which converts to a conductivity range, depending on OEM-housings, to about 0,1mS/cm to 200mS/cm. Other ranges are available on request.
Real-time Calibration and Long-Term Stability
The sensors offer real-time calibration to compensate for environmental influences and ensure high short and long-term stability and repeatability. This makes them ideal for mass production where instrument quality is required. Real-time analysis of fluid quality can meet strict regulations, improve safety and health standards and increase production efficiency through predictive maintenance and process optimization.

QCRC – Non-Contact Quality Sensor for Analyzing Fluid Properties
The QCRC sensor from EBE sensors + motion is a high-precision, non-contact quality sensor for determining fluid properties. Developed for OEM applications, the QCRC combines compact design with advanced measurement technology and enables reliable analysis of liquids without direct contact with the medium.
Features of the QCRC Sensor
- Non-Contact Measurement
The measuring electrodes are integrated on the rear of the circuit board. The sensor does not require any direct contact with the liquid for measurement. This makes the QCRC ideal for sterile or hygienically sensitive applications. - Dual Sensor Output
The sensor provides both capacitive and resistive values for the medium. The capacitive value is a measure of the relative permittivity εr, while the resistive value indicates the conductivity (σ). This enables a comprehensive analysis of the medium composition. - High Measurement Accuracy even with Difficult Media
The QCRC offers outstanding sensitivity and repeatability—even with liquids that have very low relative permittivity (εr < 2) or high viscosity. Even thick, highly adhesive residues do not affect the measurement. - Reliable Media Detection and Auality assurance
The combined measurement of two substance constants enables fluids to be clearly identified, concentrations determined, and changes in quality detected over time.
Advantages for OEM Applications
- Easy integration into existing systems thanks to compact design and integrated electrodes
- Sterile and hygienic applications possible, as no parts in contact with media are required
- Cost-efficient solution thanks to dual measuring function in one sensor
- Suitable for viscous and pasty media, such as those found in the food industry, medical technology, or chemical process monitoring

Versatile Application Possibilities
The EBE quality sensors for fluids are able to detect gases, liquids, solids and highly viscous media, even without direct contact with the medium. They can be installed in special hygienic, robust or miniature housings and offer real-time measurements for a wide range of applications. Using EBE fluid quality sensors reduces the need for frequent laboratory testing and the associated costs. Contamination or undesirable changes in fluid properties are quickly detected, allowing immediate action to prevent safety and health issues.
