Traffic Detection Coil With Good Quality Loop Coil On Sale

Traffic Detection Coil 

Traffic Detection Coil working principle. Before introducing the principle of the traffic detection coil, we will introduce what is a traffic detection coil. The "traffic detection coil" is an oscillating circuit. It is constructed in such a way that a circular groove  is formed on the ground, about 1 meter in diameter, or a rectangular groove of comparable area, and two to three turns of wire are buried in the groove, which constitutes An inductive coil buried in the earth's surface, this coil is part of an oscillating circuit. It consists of an oscillating circuit and a capacitor. The principle is that the oscillation is stable and reliable. This oscillating signal is sent to the frequency measuring circuit composed of the single-chip microcomputer through the conversion. Measure the frequency of this oscillator. When there is a large metal object such as a car passing through, the change of the oscillation frequency increases when there is a metal object), and this change is used as the confirmation signal of the car through the "traffic detection coil". The key to the technology is that the designed oscillator is stable and reliable, and the frequency changes significantly when the car passes. loop detector coil, traffic sensor coil, traffic detection coil with longtime lifespan. If you want to know more detail information about traffic detection coil. please feel free to contact us. we will send it pictures and detail specification to you. About the color of the wire. we provide black and red for your choice. and specifications was 305meter 1 circle. 

The electronic weighbridge is an oscillating circuit that detects if there is a speed through which the car passes and passes. The principles of action are:  first, create a circular groove on the ground, about 1 meter in diameter, or a rectangular groove of equal area, embedding two or three turns of wire in the groove, which constitutes a buried traffic detection coil on the surface.  This coil is part of the oscillating circuit, which consists of an oscillating circuit. The frequency of the oscillator can be measured by converting the oscillating signal to a frequency measuring circuit composed of a single chip microcomputer. When there is a large metal object such as a car passing through, the change of the oscillation frequency is caused by the change of the space medium (the oscillation frequency increases when there is a metal object), and the single-chip microcomputer can measure the frequency value of the change, that is, it can be perceived that the car passes by. At the same time, the time interval between the beginning and the end of this signal can be used to measure the moving speed of the car.
