Vehicle Loop Detector

Shenzhen Jutai vehicle loop detector Introduction Q. What is an inductive loop vehicle detector and how does it work?  A. The complete detector consists of a loop of wire and an electronic detection unit.  The operation is based on the principle of metal detection.  As an example, a metal detector has a movable “coil” (or loop) which is waved above a buried metal object, which disrupts the electrical field generated by the loop and causes the metal detector to respond with an output, usually an audible tone.  With a vehicle detector, the loop is buried in the roadway and the object to be detected is a vehicle.  When the loop detects the vehicle, the detector provides a relay switch closure output.  Q. What is a loop coil?  A. The loop consists of one or more turns of wire located in or under the pavement and wound in a square, rectangle or circular form.  There are two types of commonly used loops, the “saw cut” loop and the “preformed” loop. Q. How is the detection/loop syste

High quality vehicle loop detector manufacture Main features  - Single or Dual Loop Detector - Automatic adjustment of detection level - Pulse or presence relay output  - LED indication for power,relay status, loop fault Applications The new Loop Detector for vehicle detection continues the Carlo Gavazzi tradition of providing superior sensing technology and solutions for the door and entrance control market. The pulse mode relay can be configured to activate when the vehicle enters or leaves the loop. The output signal is useful for controlling all kinds of doors, shutters, swing gates, sliding gates etc.Typical applications for inductive loop vehicle detectors include: · Safety loops · Arming loops · Entry and exit loops Email :sales8@jutairfid.com WhatsApp :+8618179436123

Loop Installation Guide 1. The detector should be installed in a waterproof housing as close to the loop as possible. 2. The loop and feeder should be made from insulated copper wire with a minimum cross-sectional area of  1.5mm 2 .  The feeder should be twisted with at least 20 turns per metre. Joints in the wire are not  recommended and must be soldered and made waterproof. Faulty joints could lead to incorrect operation of the detector. Feeders which may pick up electrical noise should use screened cable, with the screen earthed at the detector. 3. The loop should be either square or rectangular in shape with a minimum distance of 1 metre between opposite sides. Normally 3 turns of wire are used in the loop. Large loops with a circumference of greater than 10 metres should use 2 turns while small loops with a circumference of less than 6 metres should use 4 turns. When two loops are used in close proximity to each other it is recommended that 3 turns are used in one and 4 turns in t

How a Loop Detector Works??? The loop is placed under the road surface, usually in a rectangular shape, at a depth of around 50mm. This keeps it out of view and reduces the likelihood of anything going wrong. It is then connected to a loop extension cable, often using an M12 connector, which joins up with the actual loop detector. A magnetic field runs from the loop to the detector and if no traffic is present this remains at the same frequency. The detector monitors the fre quency and if a vehicle passes over it will change the frequency. This causes the relay to close and triggers the reaction — for example, it opens a gate or changes the traffic lights. Once the vehicle has gone past, the relay will open again, closing the gate or changing the lights back again. The loops can be purchased pre-assembled, allowing them to be easily fitted into the required position. They come in a number of different sizes, making them suitable for a range of applications.

Shenzhen Jutai loop detector prides itself on being the loop experts.Now we are better able to offer gate installers more in depth technical support. If the wires of the loop itself are twisted, will it have an effect on its ability to detect vehicles? That is what we set out to clarify with our new test. Purpose of the test: 1.Observe and record if twisted loop wire has any different detection than untwisted loop wire. 2.Dispel the myth that a twist in the loop wire will cancel the EMFs (Electromagnetic Fields) causing a reduction in loop detector performance.

Traffic management helps the existing freeway system work smarter and more efficiently to promote smooth, safe and consistent traffic flow. You’re in bottleneck traffic on the freeway. Maybe there’s an incident or a lane closed up ahead. Seeing neither, you wonder what’s going on? It’s the basic economic concept of supply and demand. In terms of congestion management, bottlenecks occur when traffic demands exceed the available roadway space, or freeway capacity.  For decades, Caltrans has implemented several technological strategies for congestion relief and to provide measurable benefits to the transportation network and to the public. District 7 uses technology in various ways to better manage freeway congestion and to better communicate real time traffic situations to the travelling public. Changeable Message Signs (CMS), strategically placed along freeways, provide real time information on travel times and traffic conditions. Motorists can benefit from CMS information to take
