Microwave Bistatic Detectors "Forteza" FMW 3/2 (50 m.)

1. PURPOSE

The purpose of local protective microwave detectors of "FMW-3", "FMW-3T", "FMW-3V", "FMW-3TV" families (hereinafter referred to as the detector) is to protect perimeter sectors of different sites.

2. GENERAL INFORMATION

2.1. The detector is a bistatic microwave detector consisting of a transmitter and a receiver.
2.2. 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.

3. DISTINCTIVE FEATURES

3.1. High noise immunity.
3.2. The detector is immune to the influence of strong electromagnetic fields (power lines up to 500 kV).
3.3. The detector can detect a crawling intruder in case of special preparation of a sterial zone and sensitivity adjustment.
3.4. Microstrip production technique of microwave modules.
3.5. "FMW-3T" family microwave modules: extended temperature range, advanced reliability.
3.6. "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 2ExicIIBT6X.
3.7. Operating frequency - 9,4 GHz or 10,525 GHz
