MICROMAX has announced the Banner R-GAGE QT50R adjustable-field and retroreflective radar sensors for detecting vehicles.
The adjustable-field and retroreflective models allow the R-GAGE QT50R to solve more diverse and complex vehicle detection applications, effectively detecting trains, cars, trucks and cargo alike.
The QT50R uses Frequency Modulated Continuous Wave (FMCW) radar to provide reliable detection of moving or stationary objects in areas where photoelectric, ultrasonic and magnetic sensors fail to perform.
According to Micromax, magnetic sensors may be affected by the electric current of trains, while ultrasonic sensors are susceptible to the interference caused by the wind of passing trains. Optical sensors are vulnerable to accumulating dirt and dust.
The QT50R adjustable-field radar sensor emits a well-defined beam of high-frequency radio waves from an internal antenna, which processes the signal reflected back to the receiving antenna.
The retroreflective model complements the adjustable-field model by effectively sensing stationary targets with poor or no radar reflection through the use of a reference signal, or retro-target.
Emitting the same high-frequency waves as the adjustable-field model, the QT50R retroreflective radar sensor delivers a narrow effective sensing beam and ignores objects in the background beyond the retroreflective target.
