DualFusion Technology – two measurement principles, one goal: maximum process reliability
The capacitive measurement detects the level via changes in electrical capacitance.
Additionally, the conductive measurement evaluates the electrical conductivity of the medium and supports signal processing.
This enables the sensor to:
-
reliably distinguish between medium and build-up
-
remain stable under coating conditions
-
compensate process fluctuations
The conductive signal is processed internally to increase measurement reliability.

Point level measurement in liquids with capacitive sensors
Point level measurement in liquids is a key element in modern process industries. Especially in food, pharmaceutical and chemical applications, reliable detection is essential for process safety and plant availability.
Capacitive point level sensors are widely used, but they often reach their limits in conductive, adhesive or highly viscous media. Build-up on the sensor or fluctuating conductivity can lead to false switching or unstable signals.
Micronivo® MI 7 addresses these challenges with DualFusion Technology. By combining capacitive and conductive measurement, the sensor ensures stable and reliable level detection even under demanding conditions.
This makes it the ideal solution for applications where conventional measurement technologies fail and maximum process reliability is required.
FAQ – Point level measurement in liquids
What is point level measurement in liquids?
Point level measurement detects whether a defined level in a vessel is reached, exceeded or undershot. It is used for overfill protection, empty detection and process control.
How does a capacitive point level sensor work?
A capacitive sensor detects the level when the medium touches the probe. The change in electrical capacitance is used to generate a switching signal.
What challenges occur with conductive or adhesive media?
Conventional capacitive sensors may suffer from false switching, drift or unstable signals due to conductive build-up or changing conductivity.
