Double Way Loop Detector With China Supply Vehicle Detector

Double Way Loop Detector

Double Way Loop Detector reset button Pressing the reset button causes the vehicle detector to be manually reset during use and testing. And the induction coil is ready to probe the vehicle. The vehicle detector must be installed in a dry, waterproof and moisture-proof environment as close as possible to the detection circle. When installing the vehicle detector, keep a certain distance from other equipment or devices for easy maintenance. The ability of the traffic detection to work well depends to a large extent on the induction coil it is connected to. Several important parameters of the coil include coil material, coil shape, and proper construction. Please refer to our detailed instructions for the installation of the coil. Two-way output relays. Direction detecting function; Adjustable in 3 increments (high. Medium. Low). It has two-way output relays. Two outputs of them are unlimited when the corresponding loop is permanently covered, while the others are multi-mode that can be set by users. The direction detecting function can be used to statistics the vehicle flux. The principle is based on a change in the inductance within the loop which is caused by the metallic components of passing vehicles. The changes are picked up and evaluated by a microprocessor. Ease of use due to automatic calibration when the operating voltage is applied.

The Material Of The Double Way Loop Detector Coil: 

Under ideal conditions( regardless of the impact of all environmental factors), the embedding of the inductor coil only considers the size of the area ( or perimeter) and the number of turns, regardless of the material of the wire. However, in practical engineering,  the mechanical strength of the wire and the high and low-temperature anti-aging problems must be considered. In some environments, the acid and alkali corrosion resistance must also be considered. The traffic light loop detector will not function properly due to the aging of the wire or insufficient tensile strength to cause damage to the wire. In actual engineering, it is recommended to use Teflon high-temperature flexible wire of 1.0mm or more. The pulse reply can be set to press to the coil or leave the coil.  The sensitivity factor changes very little when a detection result is an output. (%△L/L).There are 8 levels of sensitivity adjustable in the microswitch, which is very flexible in setting and application. The time extension option allows the output signal to be extended by 2 seconds. Coil error indication The LED will indicate when the coil is open or shorted. Output relay normally open / normally closed Optional internal jumper can choose the output relay normally open or normally closed. Relay, car, no car, coil error, no power supply. double channel loop detector with low consumption. 

Feature Of Double Way Loop Detector:

1.Reliable realization of car judgment, incoming direction, and relay output.

2. Widely used in parking lots with car reading cards, railing anti-smashing cars, railings to go automatically, the car to automatically open the door and the car to automatically close the door and other controls.

3.Compact structure, separate color traces for the main unit and base for easy commissioning and installation.

4. The coil is isolated from the internal circuitry for reliability and safety.
