MWA120R/T

MWA60 and MWA120 are microwave barriers with maximum range
60 and 120 m, designed for the protection of external and internal surfaces. The
system is made up of two units. The devices are built exclusively
with solid state devices, well completed and tropicalized with resin
to provide optimal protection against bad weather.
Protective lobe
The shape of the radiation field is very well defined and this allows a probability
higher detection with minimal unwanted alarms. The issuer
consists of a planar microwave which emits a narrow and directional beam
very stable low power.
Selectable channels
The transmitter and the receiver can be tuned in frequency, through
DIP switches which allow 5 different channels to be coded.
In this way, interference is avoided in the event of simultaneous installations
several pairs of barriers.
Selective filter
Each receiver is equipped with a particular selective filter which only chooses
the frequency of his channel and refuses others, making the bypass
barrier impossible if the wrong transmitter was used.
Automatic compensation
Special self-tuning and signal processing circuits have been inserted
in the receiver, automatically compensating for variations in conditions
environmental.
Disqualification signaling
The receiver has an output which activates in the event of insufficient signal. The goal
is to prevent and report misalignments caused to a shutdown system
or by obstacles interposed in the beam of action of the barriers.
