Purpose
The purpose of local protective microwave detectors of "FMW-3", "FMW-3T", "FMW-3V", "FMW-3TV" familiesis to protect perimeter sectors of different sites.
 

General Information
The detector is a bistatic microwave detector consisting of a transmitter and a receive. The principle of the detector operation is to generate an electromagnetic field in the space between a transmitter and a receiver. The field forms a volumetric detection zone in the form of a stretched ellipsoid of rotation and registers the changes of this field when an intruder crosses a detection zone.


Distinctive Features

• High noise immunity.
• The detector is immune to the influence of strong electromagnetic fields (power lines up to 500 kV).
• The detector can detect a crawling intruder in case of special preparation of a sterial zone and sensitivity adjustment.
• Microstrip production technique of microwave modules.
• "FMW-3T" family microwave modules: extended temperature range, advanced reliability.
• "FMW-3V" family: it can be used in explosive room zones and outside facilities. Explosion protection of the detectors is provided by "spark safe electric circuit i" type of explosion protection according to GOST R 51330.10-99. Explosion protection marking is "FMW-3V", "FMW-3/1V", "FMW-3/2V"

Specifications

  • a person crosses a detection zone at a speed of 0,3…10m/sec.;
  • there is remote control of operation;
  • supply voltage is below normal one;
  • there is an attempt to mask a receiving unit of the detector;
  • there is an attempt to demount the detector;
  • the detector units are out of order.
• Probability of detection is 0,98 minimum.
• The detector supply voltage is 9…30 V.
• Maximum consumption current is 0,045 A.
• Maximum time of availability for operation is 30 sec. after power supply is ON.
• Minimum time of an alarm is 3 sec.
