Traffic Detection Coil With Low Consumption Loop Detector Coil For Sale.
Traffic Detection Coil
Traffic Detection Coil with good quality. Because Teflon has: non-tackiness, heat resistance, slide ability, moisture resistance, wear resistance, corrosion resistance, and other characteristics. Therefore, Teflon wire has better thermal stability and mechanical wear resistance than other high-temperature wires. It can resist strong acid and alkali, corrosion resistance, refractory and non-combustible, high oxygen index, low smoke and no halogen, no aging, easy to strip. High strength and friction resistance. The temperature resistance of the Teflon wire is different from that of the material of the outer casing. There are roughly three types of PTFE: PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at 260 ° C, with the highest operating temperature of 290-300 ° C, very low friction coefficient, good wear resistance, and excellent chemical stability Sex. FEP: FEP (fluorinated ethylene propylene copolymer) non-stick coating melts and flows during baking to form a non-porous film. It has excellent chemical stability and excellent non-stick properties. The maximum operating temperature is 200 °C. PFA: PFA non-stick coating melts and forms a non-porous film during baking, just like FEP. The advantage of PFA is that it has a higher continuous use temperature of 260 ° C and stronger toughness. It is especially suitable for use in the field of anti-adhesion and chemical resistance under high-temperature conditions.
In the electronics industry, it can be used for temperature compensation wires, low temperature resistant wires, high temperature heating wires, aging resistant wires and flame retardant wires; in the household appliance industry, it can be used in air conditioners, microwave ovens, electronic disinfection cabinets, rice cookers, electronic thermos, electric heaters, internal wiring of electric oven, electric wok, lighting fixtures, etc. Loop Detector Coil, Traffic Detection Coil, vehicle loop detector coil, good quality loop 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 is caused by the change of the space medium (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", and The time interval between the start and end of the signal can, in turn, be used to measure the speed of the car. This is the "ground coil". The key to the technology is that the designed oscillator is stable and reliable, and the frequency changes significantly when the car passes.
