LD-200 Dual Channel Metel Vehicle Loop Detector

Why use the JUTAI vehicle loop detectors?

With years of technology precipitation and accumulation, the vehicle detectors produced by JUTAI have won some international and European brands and domestic low-end products with excellent quality, good cost performance, and excellent after-sales service. With the recognition of more and more foreign customers and friends, we have gradually opened up the popularity in foreign countries, and the LOOP Detector has gradually formed a complete series. At the same time, we are committed to helping some Wholesaler and Dealer Provides OEM Service based on the concept of development and growing up together.

High sensitivity and frequency setting

JUTAI Loop Detector has 16 levels of sensitivity, and the customer can flexibly set the sensitivity according to the specific case. At the same time, our vehicle detector has 4 different application frequencies. For some cases with very close entrances and exits, we set different frequencies by flexible setting dialing, which effectively solves the problem that the coil distance is too short and causes the same frequency. Interference problem.

∗ These models can freely choose according to the needs of the project. We have an excellent design department to help customers OEM the brand and assist our customers to do the corresponding promotion activities in the local area to achieve a win-win situation. So what are the unique advantages of the vehicle detectors produced by JUTAI compared to the similar detector on the market? Let me list them to our distinguished guests one by one.


With Very Wide Inductive Value

∗ If the detection value exceeds 300μH, there will be a wrong function of the gate or door, the vehicle may be dangerous, and with the very narrow car type detection,many entrances and exits often have multiple types of vehicles, so the big problem is that the application is very inflexible. but JUTAI Vehicle loop detector can solve this problems.



Flexible Loop Coil Installation

∗ JUTAI Loop Detector Installation , not limit any size,We can flexibly define the installation size of the coil according to the actual situation of the case;Because our loop detector has extremely wide sense value (15 uh-2000uh),and it can easily detect various car models;However, based on the actual installation experience, we recommend that the coil inductance value be in the range of 380-400uh, the induction is the most sensitive;(Using JUTAI JTHT-11 Loop coils as the measurement standard), within the scope of this standard, the length of the induction coils is about 50m


With Wide Power Supply

∗ All series of vehicle detectors produced by JUTAI adopt the wide voltage output mode, 110-240 VAC, 12-24 VAC/DC, so that customers can purchase One model but suit two voltages, which effectively reduces customers’ inventory and Funding pressure, this feature is also an important feature that our customers like very much.


With Temperature Testing

∗ Vehicle detectors, we have to carry out rigorous quality testing for each particle, our adaptation temperature is from -40 degrees to 80 degrees, so that our vehicle detectors are in cold regions and extremely hot Middle East, Regions such as India are highly adaptable in temperature.


PH Testing

∗ Our vehicle detectors, we have a strict PH test on the selection of the device, our detector base, salt spray corrosion test can reach 15 days, and we test some domestic brands of the same class, about 3 days The device has been completely etched away.


Anti-Lighting Testing

∗ For some high-light-emitting areas around the world, such as countries like Malaysia, our vehicle detectors can withstand 100,000 volts of lightning strikes.




∗  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.



The Working Principle As Follows

∗ When the car from outside entry to Community or parking lot, Press the two loop coils at the same time, we will use JUTAI Double channels loop detector (LD-200/202) to trigger the UHF reader which at the entrance site; when uhf reader read the card ID, It will send ID to controller (AC-11) by wigand output; controller judge ID is valid, output relay signal to open gate barrier, and then car entry the community or parking lots, when car passed barrier gate, barrier arm will down automatically; (this part work with JUTAI Single channels loop LD100/102 for Safety and anti-smashing function) but when the car passed another uhf reader which connected by AC-11 also, this reader will not be triggered by loop detector again, and not send data to controller, so the software only have ENERY records; (Because the Direction Recognition Function of LD200/LD202 is enabled).

∗ In contrast, when car Exit Community or parking lot, when the car passing the inside uhf reader, LD200/LD202 trigger the uhf reader, reader read card and send ID to controller, controller judge ID is valid,output relay signal to open gate barrier; then car EXIT the community or parking lots, when car passed barrier gate, barrier arm will down automatically; (this part work with JUTAI Single channels loop LD100/102 for Safety and anti-smashing function); But when car passed another uhf reader at exit, the double channels loop detector will not trigger signal again, system will only have EXIT records; (because the Direction Recognition Function of LD200/LD202 is enabled).

∗ JUTAI LD-200/202 Double channels loop detector also can be used as two independent single channel loop detectors. This is suitable for a standard one-in and one-out parking lot, There is one barrier and one long range reader at the entrance, exit same also; one loop coils is used to trigger reader and read card, and the other loops coils is used for the barrier anti-smashing function, when the LD-200/202 as two independent loop detector application, from an economic point of view, which can reduce part of the hardware cost; (Enable the Independent working mode function of LD200/202).



How To Fast Install JUTAI Loop Detector

When we install the loop detector, how to make the speed quickly and accurately, please refer to the following text and video;

∗ JUTAI LD-200/202 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 multi-meter 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.
