美国西南防爆微波探测器 310B--33456基本介绍:


Model 310B-33456 offers reliable intrusion detection in the presence of flammable,

  combustible or easily ignitable materials. The sensor is specifically designed to operate   at oil refineries, chemical and petrochemical plants, petroleum or chemical storage   facilities and other sites where hazardous materials are handled, processed or stored.   Each 310B-33456 transmitter and receiver is packaged in a weatherproof,   explosionproof enclosure with front access to controls and test points.   The 310B-33456 operates at K-band (24.125Ghz) frequency, achieving performance not   possible with X-band microwave links (10.5Ghz). Because antenna beam width is   approximately 7.5 degrees in both the horizontal and vertical planes, the sensor will   operate within very narrow corridors.   Because K-band frequency is 2.5 times higher than X-Band, the multipath signal   generated by an intruder is also 2.5 times higher and detection of slow-moving intruders   is correspondingly better. With its superb beam control and higher multipath frequency,   Model 310B-33456 provides unmatched detection performance.   Phased Locked Loop (PLL) signal processing in the receiver increases detection   probability by alarming on partial or complete beam interruption, increase or decrease in   signal level or jamming by other transmitters. Its Automatic Gain Control (AGC) circuit   permits the receiver to compensate for varying site conditions or changes in the weather.   Operating at K-band frequency, Model 310B-33456 is inherently less susceptible to   interference from airport landing systems, aircraft radar or other microwave intrusion   systems. Four field-selectable modulation channels with narrow band PLL filters allow   several Model 310B-33456 links to be used together without mutual interference.
