Vehicles Loop Detector System 2. Introduction: when vehicle coming to gate, It can use underground with loop coil of change of frequency It also use one by one (1 loop coil into ground easily detected by 1 loop detector. When detector completely set up once time. It is not affected by any change of temperature, humidity,and no circumstance.It has installed AUTOMATIC FREQUENCY CONTROL) It can easily control by automatic frequency itself 3.
