2.5.2 Detector unit
The detector receives the transmitted pulsed radiation signals from the source. The signals
are then amplified and fed into an analog to digital signal converter to be processed by the
internal microprocessor.
When the signals drop below a prescribed level, the internal microprocessor compensates
for them. This allows the signals to be maintained even in severe weather conditions. The
data is sent to the output interface section.
The front window of the detector is heated to improve performance in icing,
condensation, and snow conditions.
There is one detector type that is suitable for all models
