What are guided radar sensors?

Principles of guided radar sensors

Guided radar sensors can be used for level measurement in liquids and solids.

The guided radar pulses along the probe ensure a precise and stable measurement even with dust and foam forming media.

High frequency microwave pulses are transmitted along a steel cable or a rod. When impinging on the product surface, the microwave pulses are reflected. The transmitted wave and its reflected time by the medium is evaluated by the device and output as a level value.




The evaluation of the sensor uses a 4-20mA HART-signal.  The start and end points of the  measuring length depends on the used medium.
