Product Descriptions

An inductive loop detector is an electromagnetic communication or traditional traffic detection system which mostly uses buried coils and moving magnets to induce an electric current. And it is currently the largest amount of traffic detection devices in the world.

The embedded toroidal coil type vehicle detector is mainly composed of a regulated power supply, an oscillating coil, a logic circuit, a microprocessor, an interface, a driving circuit, a signal output circuit, an induction coil, and so on.
A vehicle detector is based on the principle of electromagnetic induction. A group of ring-shaped induction coils with a certain working current are buried in the roadbed section of the same lane. When the vehicle passes or stops in the annular buried coil, the vehicle itself cuts the magnetic flux line, causing the wire loop inductance. The amount of change, the detector can detect the passing state of the vehicle by detecting the change of the inductance, and transmit the state signal to the vehicle detector, which collects and calculates the flow rate, speed, time occupancy, and length of the vehicle, and so on. Traffic parameters are uploaded to the central control system to meet the needs of the traffic control system.

Function and Advantage  

   Wide range of detection:
   The detecting range can be from 15UH-2000UH, the loop detector can be in stable work status no matter the inductive value         how changes.

    Many types of vehicles can be detected:
    It can detect many types of vehicles with different heights and weights, like Motorcycle, Truck, Car, Bus, etc.

    Adapt to the bad environment:
    For all of our loop detectors we do temperature tests and corrosion tests (-40 degrees to 70 degrees), let it always keeps                outstanding performance.



Connections
The following photo we show the details connections for JUTAI Single channel loop detector LD100 And LD102,Usually we using pin1 and pin2 connect power supply, pin8 and pin9 connect loop coils,Usually we recommed JUTAI Loop cable Mode JTHT-11;pin5 connect GND,details info refer to the following connection;

Detector Position and Installation
1. Install the detector in a weatherproof housing.
2. The detector should be as close to the sensing loop as possible.
3. The detector should always be installed away from strong magnetic fields.
4. Avoid running high voltage wires near the loop detectors.
5. Do not install the detector on vibrating objects.
6. When the control box is installed within 10 meters of the loop, normal wires can be used to connect the control box to the loop. More than 10 meters requires the use of a 2-core shielded cable. Do not exceed 30 meters distance between control box and loop.

 Loop Installation
The loops are sealed using a "quick-set" black epoxy compound or hot bitumen mastic to blend with the roadway surface.
When installation, please keep the product plug and socket in the vertical direction

 

Application
JUTAI LD200/202 double channels vehicle loop detector series, it with direction recognition function, and which is suitable for many single-channel entry and exit cases.
JUTAI LD200/202 double channels loop detector connect to JUTAI One door controller (Model: AC-11), JUTAI gate barrier (Model : BR-110), and JUTAI long range RFID reader (Model : PUHF-9), combined with high temperature resistance loop coils (Model : JTHT-11), Which can be perfectly applied to single-channel entry/exit access control system.

JUTAI LD-100/102 series vehicle detectors have a large sensing range, and the adaptive sensing range is 15 uh to 2000 uh; this can easily detect various large and small type vehicles, such as small and electric vehicles, Motorcycles, conventional cars, cars, trucks, trailers, trailers, etc.; but if we use the loop coils value reach to 2000 uh, then we need a lot of high temperature wire (Model:JTHT-11), which will cause material Waste, increase the hardware cost of the project, and the actual application does not need so many wires, usually we set the inductance in the range of 300 uh, and take the coil size of 1 meter wide and 2 meters long as an example , We suggest do 8-10 turns, which inductive value can easily detect all kinds of car models, then if we want to do the fast installation , first we do a loop coils, 1m wide, 2m long, assuming 10 turns, We use a multimeter to measure the inductance value of these 10 turns, and then according the parking entry/exit channel size is different, we can flexibly set the size of the coil within this inductance value range. If the diameter of the coil is smaller, then we do more turns; If the diameter of the coil is larger, we do less; so that it can be flexibly applied to entrances and exits of various sizes, and the overall installation efficiency is improved.
