Active Shield: Reliable measurement despite material build-up
The protective shield against false switching
Material build-up is one of the most common sources of interference in level measurement. Whether sticky powders, slurries or conductive bulk solids – as soon as material adheres to a probe, the risk of false switching increases. Moisture or condensation on the sensor probe can also cause capacitive interference.
Active Shield refers to an active shielding technique in which an additional protective field prevents false switching caused by material build-up. This is exactly where Active Shield Technology comes into play: it ensures that the sensor reacts exclusively to the actual medium – not to external disturbances. The result is stable, reliable measurement signals, even under demanding process conditions.
