Distance measurement through a cover
- Measuring distances to 8.5 m
- Continuous measurement signal plus discrete switching signal
- Ideal for objects covered or protected by a semi-transparent material
Radar barrier for easiest object detection
- Measuring distances from 0 to 8.5 m
- Fast response time (5 ms)
- Ideal for object with irregular surfaces
Your benefits
- Designed for extreme environments
- Can be used outdoors and in a wide temperature range of -40 to 65 °C / -40 to 150°F without additional protective housing. The sensor withstands stress tests such as IP68 / IP69K test and the even more demanding proTect+ without any problems
- Reliable measuring signal even in harsh environments, ambient light and dirt
- Great accuracy < 1 mm and low temperature drift < ± 10 mm
- Low total cost of ownership through a very robust casing
- Highest chemical resistance due to a robust casing (stainless steel housing with Ecolab Certificat and thermoplastic polyetherimide (PEI) front surface)
- Easy and versatile positioning
- The radar sensor is available in a very small housing so that it can also be installed in confined spaces
- Fast measurements and reaction to positon changes
- Very fast response times < 5 ms
- Distance measurement in a small cone over long distances
- Focused, very narrow beam profile with measuring distances to 40 m
- No signal detortion through neighbouring objects
- Focused, very narrow beam profile
Applications
- Wheel positioning and vehicle measurement in car-wash plants
- Position detection at crane bridges, crane trolleys, transfer trolleys
- Positioning and inspection at belt conveyors
- Detection and positioning of large moving objects (e.g. trains)
- Measurement of distance towards road or tar pavement
Carwash vehicle positioning and measurement
- The radar sensor measures car position and size, allowing ideal brush positioning in drive-through and tunnel car-washes.
- The sensor signal is unaffected by water spray and associated cleaning agents.
Height regulation of arms e.g. of cranes
- The radar sensor measures the height of the arm relative to the ground or a corner cube.
- The sensor signal is unaffected by adverse environmental conditions.
Technology
Distance measurement to flat or round objects
For flat objects it is very important that the tilt of the surface is not greater than half the opening angle. This is to ensure that radar beams reflected from the surface are reflected back into the sensor for proper detection. Round objects have the advantage that they are rotationally symmetric. This makes alignment much easier, as round objects always reflect something back to the sensor. Compared to a flat object with comparable size, the signal strength of the reflected beam is reduced.
Distance measurement through a cover
Radar beams can penetrate certain materials (such as plastic panes). The covers do not require full transparency to be penetrated by radar beams. For example it is possible to look through black plastic sheets. A small portion of the radar beam will be reflected back to the sensor from the cover. Through a special teach-in-algorithm the sensor learns the profile of the reflection. It subsequently measures objects behind the cover, as if the cover is none-existent.
Radar barrier for the most reliable object detection
The radar sensor is also available in a configuration, where it operates similar to a light barrier. Via a special teach-in-algorithm the sensor learns the reflector position. After teaching the sensor monitors the reflector position. If an object breaks the line of sight between the sensor and reflector, the sensor output switches. The advantage of this configuration is that it is unnecessary for the object to reflect a signal back to the sensor. Therefore even randomly-shaped objects or radar absorbing objects can be reliably detected.
- Baumer radar sensors use FMCW technology
- The distance and relative speed of an object can be measured
- The use of high frequencies creates a compact design and a narrow beam profile
- Sensors remain reliable and impermeable over their entire service life
- Shock-tested over the entire temperature range to simulate aging effects
- IP 69K protection against ingress of dust and high temperature, high pressure water
