Radar-based sensor

January 2009 Sensors & Transducers

Reliable detection of moving and stationary objects.

Banner Engineering has introduced the R-GAGE QT50R, an advanced radar-based sensor for close and long-range presence detection in a broad range of weather conditions. The QT50R features frequency modulated technology to accurately monitor or detect objects while resisting rain, wind, humidity and extreme temperatures.

The sensor uses frequency modulated continuous wave (FMCW) radar to detect moving or stationary cars, trains, trucks and cargo. The QT50R detects target objects up to 15 m away and ignores anything beyond the set-point. The IP67-rated sensor operates at 24 GHz in the industrial, scientific and medical (ISM) telecommunication band.

“The cutting-edge QT50R features FMCW true-presence radar paired with exceptional environmental resistance, allowing the sensor to operate in heavy precipitation and temperatures ranging from -40 to +65°C,” said Mike Dean, Banner Engineering product manager. “The units are easy to configure and feature bright indicator LEDs for simple status monitoring in a robust housing with a 30 mm threaded mounting base to provide versatile installation options.”

Applications include:

* Anti-collision of overhead cranes.

* Train and tram detection and location in tunnels.

* Cargo positioning and detection on a truck bed.

* Truck detection at a loading dock.

* Access control to parking ramps and garage doors.

* Car detection in drive-thru areas.

* Position sensing of cranes.

* Measuring and pro­filing in tollbooths.

* Over height detection for tunnels and bridges.
