Long Distance Metal Detecting Sensor
Unlike conventional metal detectors, SNOOPER uses the variation of Earth magnetic field. In order to detect the movement of an iron object from a long distance away, extremely high magnetic sensitivity is required up to that of military sensor of SQIUD that is used for detecting submarine under the sea.
This idea of the detection of armed human movement using a precise magnetic sensor was first developed by MAGO technology, and finally MAGO technology made this idea possible successfully.
SNOOPER has the unique magnetic sensor structure of hybrid system(analog + digital), and also adopted with the cutting edge technology of digital signal processing algorithms to detect a nano level perturbation of Earth magnetic field. SNOOPER is more sensitive than any other conventional magnetic instruments by 1000~10,000 times except SQUID.
SNOOPER also can be used to build up an innovative invisible detection fence around important facilities to detect approaching vehicles.
SNOOPER was originally developed for military purposes, but it also has many applications of securities, anti-terror systems such as an stealth inspection system for a school entrance, airports, VIP scans, etc.
In a crowded urban city, we have many kinds of magnetic noise sources. SNOOPER-DP system has a special structure for cancellation of magnetic noise around the sensor.
SNOOPER-DP system is the perfect portable and invisible metal detecting system for a theater, school, political meetings, etc.
One of the strong benefits of SNOOPER-DP is that people does not feel uncomfortable at all, even they do not notice that they just passed a security check system, so it is possible to build up a much FASTER inspection system than the conventional metal detector more than 10 times.
Vehicle Detecting Sensor with FS type magnetic technology
Unlike conventional magnetic sensor such as 3‐axis magnetic compass module, CARDET has the unique technology of FS(feedback stabilizing) magnetic sensing properties, so it can maintain the original detection areas and sensing characteristics against various magnetic noises on the road. FS magnetic sensor shows the superior stable characteristics and
performance than conventional magnetic sensors. Also FS magnetic sensor in CARDET has its own DSP and digital adaptive algorithms, and the whole performance was optimized to the car detection on the road.
The proximity sensor inside CARDET‐301 is not a conventional ultrasonic sensor but a specially designed DI(digital intergral) proximity sensor that has an extra DSP and integral measurement algorithms for stable detection. MAGO technology developed a special measurement method using integral structure and correlation signals from the target object. DI proximity sensor can extract the exact signal from the target object under various severe noises.
Conventional LOOP COILs cannot detect precisely the starting point of the vehicle when it passes by, but CARDET-301 sensor has a special function to detect the edge of the vehicle accurately, this function is essential to a counting device and the precise control of safety bar.
High reliability TRAIN Detecting Sensor
Train Sensor RA-400 is an innovative synthetic sensor that internally composed of 2 innovative sensor modules of FS magnetic and RADAR proximity sensors to detect train or subways on railways under strong EMI noises. It detects only trains and do not make false alarm for rain or snow under heavy noises on the railways.
Also RA series has the elaborate magnetic solution for detecting the movement of a train. A RA-400 can be installed at the center of the two rails, and also on the side fixture of the rail. It does not effect from heavy snow, rain and leaves.
Trains usually use high voltage of high currents for the dragging power, and they have many kinds of electrical devices those emits various noises such as AFC, motor, electric suspensions, synchronizing devices etc.
RA Series has the edge technology of special measurement structure for anti-noises, and optimized digital filters for filtering out various noises on railways.
