Vehicle Loop Detector Circuit Schematic

For high bed vehicle detection the typical loop size is 6 x 8. Extension cable which in turn connects to the vehicle detector. If the inductive loop is placed correctly it will detect vehicle open gate and keep it open until the vehicle clears the gate.

The octal connector is available as a harness or a mountable socket.

Vehicle loop detector circuit schematic.

For example a 4 x 8 loop will give a detection height between 2 1 2 and 2 3 4 feet. Observe the detection call light on the detector module for all sensitivity settings. Loop detectors are available as direct plug in for specific gate operator control boards or use a universal 11 pin octal connector. Set the sensitivity to the lowest setting that will detect a bicycle.

Into the designated loop. Good practice dictates multiple loops and detectors in this situation. Detection distance is much better with a large 6 foot coil. The loop resonates at a constant frequency that the detector monitors.

The detector powers the loop causing a magnetic field in the loop area. The number of turns in the loop is determined by the size of the loop. View more loop detector loop overview. This circuit can also be used in conjunction with my delay.

This tiny test coil was for testing only on my work bench and although it works detection distance is not very good. A base frequency is established when there is no vehicle over the loop. We carry models from emx platinum access northstar diabo mmtc liftmaster doorking reno a7e. Executive summary of the induction loop vehicle detector.

The time will be calculated by arduino when the vehicle interrupts the start laser the timer begins and when the vehicle interrupts the end laser the timer stops and applying the values to the equation arduino will find the speed of the vehicle. Drive a large vehicle over adjacent lanes loop detectors and observe if a false call spillover is detected. A circuit used to detect a vehicle on blacktop pavement concrete and trigger an alarm or relay. An induction loop vehicle detector comprises an oscillator circuit having a plurality of capacitors switchable in circuit with a road loop under the control of a microcomputer to determine the oscillator frequency.

Loop detector schematic modified to drive a relay. The microcomputer monitors the oscillator frequency and controls the switching of the capacitors to periodically return the frequency to a predetermined value.
