Vehicle Loop Detector

Loop Design Essentials /Loop wire/ Loop detector installation Proper installation of the loops is essential for reliable vehicle detection. Most vehicle detector problems are caused by improper loop installation! „ The geometry (shape and size) of the loop defines the detection zone. See the figures to the follow for typical loop geometries used for access or traffic control. „ Loop sizes may differ and will depend on lane width, traffic patterns, and types of vehicles to be detected. The following guidelines are typically used today with most access control applications: ƒ Large rectangular loops (4’ x 8’, 6’ x 8’, 6’ x 12’ are used to detect larger vehicles and high bed vehicles (trucks). ƒ Small size loops (i.e. 2’ x 5’, 3’ x 6’, 6’ x 6’) are used to detect smaller vehicles, such as motorcycles and automobiles. Important Note: Typical detection height is about 2/3 of the shortest leg of the loop. Adjacent loops operating on separate vehicle detectors may interfere (cross-talk) w...

Vehicle detector  principle vehicle detector is the use of LC oscillator to detect whether there are metal objects at the coil to achieve the detection of the vehicle. Vehicle detector has a fixed capacitance, and then in the ground around a 3-5 m long coil, when the coil is not the vehicle when the inductance is relatively low, LC oscillation frequency is relatively high, the frequency is greater than 50Hz, when the coil has Vehicle, the inductance increased sharply, the frequency of lower-end LC oscillation, this time the frequency is less than 50Hz. Vehicle detector can be based on the frequency of LC oscillation to determine whether there is a vehicle through. In this case, Vehicle detectors are commonly used in parking lot systems. A, Vehicle detectors are used in conjunction with the barrier, and the B vehicle detector is used in conjunction with an automatic card reader. In this case, When the vehicle detector and the barrier with the use of vehicles at this time detector ...

Jutai's Loop detector Matrix is available in multiple models, and single and double channel modes to accommodate nearly any application. The detector features compact housing with a standard 11-pin industrial connection, and uses power supply configurations of 110-240 VAC or 12-24 V AC/DC. single and double digital induction loop detector provides vehicle access control and safety for doors and gates in industrial applications. The detector has advanced settings that allow users to customize detection fields and time of activation to best fit their needs.
