Vehicle Double-Way Detector With Loop Detector Coil For Parking System
Vehicle Double-Way Detector
Vehicle Double-Way Detector with competitive price. The vehicle Double -Way detector will automatically calibrate when the power is turned on. The calibration process takes about 1 second. When the calibration is in progress, the two LEDs on the panel are always on. There should be no cars parked on the coil during calibration. When the calibration is successful, the “Detect” indicator on the panel goes out. When there is a car passing through the coil, the “Detect” indicator on the panel lights up and the relay A1 or B1 closes. If the coil is not detected during the calibration process, the corresponding indicator on the panel will flash continuously. Customer can amend loop coil working frequency and avoid interface of close coil loop or working frequency. The sensitivity of the vehicle Double Channel detector is specially optimized for the parking system. When lower values are selected, it will respond well to vehicles with higher chassis or trailers, while smaller metal objects such as bicycles and trolleys will not cause The detector acts. The sensitivity of vehicle double-way detector adjustment uses the rotary encoder switch on the panel. There are ten files. The "0" is the lowest and the "9" is the highest. The code switch A on the left side corresponds to the coil A, and the code switch B on the right side corresponds to the coil B. In the test run, first set the sensitivity to the low level. After the actual test, if the double loop detector does not respond, the sensitivity should be increased by one step. This is repeated until the vehicle loop detector is normal and stable.
The vehicle double-way detector of coil material: comprehensive mechanical strength, high and low-temperature anti-aging, acid and alkali corrosion resistance of the wire in actual engineering, it is recommended to use Teflon high-temperature soft wire of more than 1 square nylon sheath can be considered for projects with harsh environmental conditions and long lead wires. Compatible with all kinds of parking systems in the country, the industrial controller, the car does not fall. Widely used in a various sense has a power indicator and output detection light, sensitivity adjustment and reset switch.
Mutual crosswalk of the vehicle double-way detector coils when the two induction coils are close together, the electromagnetic fields of the two coils cross each other, and crosswalk can lead to erroneous detection results. (eg deadlock of the replay). In the same area, when the same vehicle detector and the detection coil are used and the detection loop is relatively close, large crosstalk is generated. A series of measures can be taken to reduce crosswalk. To increase the spacing of adjacent coils, it is necessary to ensure that the distance between the detecting coils is more than 2 meters. The outlooks of the vehicle double-way loop detector are very important. Because a different country has a different requirement.
