Precision Measurement and Calibration: Electricity
The attenuation of the modulation-frequency power delivered from the output of
the microwave detector is measured by a standard attenuator such as a standard
ratio transformer. The range of attenuation measurement, as in i.f. substitution ...
When there is air or vapour present inside the vessel, strong microwave signals
are received at the receiver end and detected by the microwave detector. As the
level of process material increases, it brakes the transmission of microwaves and
...

Home Security: Alarms, Sensors and Systems
As with the microwave detector, the use of the Doppler principle gives the device
a high sensitivity to movement towards or away from the detector. It is less
sensitive to sideways movement. The passive infra-red sensor has the opposite ...
Microwave detector diodes can be classified into two categories, one is crystal
diodes or point contact diodes and the other one is Schottky diodes. Both the
types are widely used for detection and mixing. Structurally, crystal diode consists
of a ...

To reflect back to an earlier example, if water is flowing down a drainpipe in the
wall, the microwave detector might detect the motion and think it is an intruder,
but the infrared sees nothing. The reason being that the infrared energy is
blocked ...
