High quality Jutai Loop Detector LD-100

-
Jutai Loop Detectors are designed for installation into hot asphalt overlay, concrete overlay, cut-in, or as a temporary above ground "stick-on" loop detector. Loop provide cost-effective, reliable installation in harsh environments.
Application:
Loop cable has multiple application, e.g. road crossings (with traffic lights), highways, car parking, traffic counting systems, speed detection etc.

vehicle loop detector / loop sensor/ traffic loop detector/ boom barrier/ single loop detector manufacture This is Una Lee from Shenzhen JUTAI Comm Co., Ltd. We are loop detector manufacture. we know that you are need loop detector in your market. Do you know why choose Jutai loop detector?   1.The inductive range is from 20uh-2000uf, nearly all types of different vehicle can be detector (bike, motorcycle, bus, car,truck,tailer,ect) 2.JUTAI Loop Detector is designed to accommodate numerous applications, can be adjusted intelligently to any environments and virtually eli minating false detection. 3.On the front panel, the four selectable loop frequencies (20~80KHz) can completely eliminate any crosstalk. If intermittence happen or failed loops get self restored, the detector will resume to normal operation without manually reset the detector. 4.Two separate output relays:   Output A is presence output. Can be extended for 0, 2, 5, 8, 10, 15...

Vehicle detector principle

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 ...

WARNING: 1) Installation and operation by service personnel only, 2) Disconnect power before working on this unit. A correct loop configuration and detector installation will ensure a successful inductive loop detection system. OPERATIONAL CONSTRAINTS Cross talk When two loop configurations are in close proximity, the magnetic field of one can overlap and disturb the field of the other. This phenomenon, known as crosstalk, can cause false detects and detector lock-up.  Crosstalk can be eliminated by: a. Careful choice of operating frequency. The closer together the two loops, the further apart the frequencies of operation must be. b. Whe...
