Microwave Sensors for
Industrial Door Safety
Microwave Sensors, also known as
Radar or Doppler sensors have been used to activate industrial automatic doors
and gates for decades. Ever changing standards and requirements have motivated
sensor manufacturers to refine this technology and develop more flexible,
reliable microwave sensors for industrial use.
The microwave sensor sends out a
high frequency sound wave while listening for bounce back. When the sound wave
is returned at a different frequency the sensor knows that there is a moving
object within the detection zone. It then sends a signal to the internal relay,
which is wired to the door control's activation input.
Bircher-Reglomat uses the latest
technology in microwave detection. Utilizing the planar or flat antenna, at
24.125 GHz in the K-band range gives our sensors the capability of achieving
the sharpest, most adjustable detection field possible with today's microwave
technology.
