Capacitive Level Measurement of Demanding Media
In the field of capacitive level measurement, EBE presents its high-quality corTEC® level sensors, which are perfect for measuring the level of media that are difficult to detect. These products are particularly suitable for:
- The detection of media with low conductivities.
- The measurement of viscous, adherent and paste-like media in the food beverage industry as well as for liquid, granular and powdery media and a wide variety of bulk solids.
Advantages of capacitive level measurement with corTEC® sensors
The corTEC® level sensors are equipped with an automatic calibration function to minimize short and long-term measurement errors. These versatile sensors can be implemented as limit switches or continuous sensors and offer various designs, including:
- Immersion measurement caps for non-conductive tank materials or flat attachment to the outside of the tank.
- Screwed into conductive tank walls as level switch, available with stainless steel tip for granular media or with PEEK or plastic cap.
- Sensors for contactless detection of fill levels from the outside.
Product details of the EBE level sensor LCRB0001D:
- Optimized for limit switch applications
- Accuracy typ. +/-1mm
- Excellent sensitivity and accuracy even for materials with a dielectric constant of εR <2
- Data Sheet Level Sensor LCRB0001D
- Short Description Level Sensor LCRB0001D
- Design Guideline Level Sensor LCRB
- I2C Protocol Level Sensor LCRB
LCRC level sensors for adhesive media
The LCRC sensor is also based on corTEC® technology and measures the level entirely from the outside. Even if there is heavy adhesion inside, the measurement signal remains stable because the sensor detects the change in capacitance of the actual medium—not that of the adhesive layer.
This makes it suitable for monitoring demanding media such as blood, glycols, detergents, or similar liquids with variable viscosities and adhesion properties. In many plants, residues, foaming, or biofilms hinder precise level detection. LCRC sensors offer a reliable alternative in such cases.
The advantages of LCRC level sensors at a glance:
- Non-contact measurement through the container wall
- Reliable detection despite adhesions and critical media
- Minimal space requirement (30 x 30 mm)
These characteristics make the sensor particularly suitable for the following areas of application
- Laboratory and analysis equipment
- Medical technology
- Compact process containers
- Dosing and cleaning systems
- Cooling and heating systems
- Small chemical and biotechnological systems

Customized capacitive level measurement for individual projects:
Our customer-specific sensor developments are based on specific requirements and characteristics of the customer’s application. The proven basic algorithms and technologies, such as corTEC®, are individually adapted to the respective requirements.
The geometry of the sensors is precisely matched to the installation space, and thanks to close coordination with the customer’s design department, assembly and production plans are created for large series. 3D field simulation enables the optimization of the electrodes for application and environmental conditions.
EBE sensors + motion realizes interfaces, connectors and the form of the signal output exactly according to customer requirements. This allows their requirements for capacitive level measurement to be integrated quickly and easily into their existing environments.
