Radar sensors for distance measurements and positioning

Radar sensors for distance measurement must be powerful in order to always measure accurately and reliably, even in complex industrial environments. accurate and reliable measurements even in complex industrial environments. Thanks to their unique measuring precision and real-time measuring rate, Kübler radar distance sensors are ideally suited for use in industrial applications - even under harsh conditions. The high-precision radar sensors have no moving parts, function without contact and rarely need to be cleaned. Even with dirt on the lens, the radar sensor usually measures absolutely reliably.

Radar sensors for distance measurements and positioning

A radar sensor for distance measurement measures the distance between a reference point on the sensor and a target object. The sensor transmits the changing distance value to a controller via an interface. The faster the measured distance changes, the more frequently the sensor has to measure in order to correctly map the change in position. The measuring rate of a distance sensor is therefore just as important a quality criterion as its measuring accuracy and range.

Maximum signal strength

Mounting bracket for optimum alignment of the sensor to the application

Precise alignment of the sensor to the measurement object is crucial for optimum measurement results. The maximum signal strength of the reflected radar wave is achieved by aligning the radar sensor at right angles to the surface of the measurement object. Especially with a narrow aperture angle, the tolerances for a deviation from the vertical are relatively small in order to receive a signal at all.

For quick and precise alignment, corresponding mounting brackets are available for the RAD5xx series.
RAD5xx series, either for rotation about one or two axes perpendicular to the measuring direction.

Angle reflector for optimizing the signal strength in the application

Uneven surfaces or problematic focusing on a target object at a greater distance can strongly influence the signal strength of the radar signal to be received. Angle reflectors can help to increase the signal strength for greater measurement accuracy.

Angle reflectors "bundle" the radar signals over a larger area. The geometry is designed so that reflections at any point (b+c) travel the same distance to and from the sensor as the direct reflection (a) at a 90° angle.
