Single Vehicle Loop Detector

Single Vehicle Loop Detector Price  Single Vehicle Loop Detector for sale Loop Detector Troubleshooting Vehicle Detector Loop Detector Price A single-vehicle loop detector typically consists of three components. The induction loop is made up of a simple cable that is buried under the road. The detector electronics are primarily connected to the electronic device via a cable. The presence of the vehicle on the loop can be detected to provide an output. Controllers, typically used for parking, transportation or industrial door/door applications. Detector tunes to loop.

Single Vehicle Loop Detector

The ferromagnetic effect of the loop sense coil - the loop inductance increases the eddy current - the loop inductance reduces the ferromagnetic effect of the eddy current. The inductor loop is the coil of the insulated conductor, using a specific geometry, which is low by the detector electronics. Voltage signal excitation. The resulting magnetic field will surround the coil core of this cycle. When the power source is applied to a vehicle detector connected to the loop, the electronic device will automatically tune to the coil loop. The loop oscillates at the natural resonant frequency of the particular loop

The Vehicle Loop Detector coil oscillates at the natural resonant frequency of the particular Vehicle Loop Detector coil to which the electronics are connected. The frequency is directly affected by the capacitance and inductance in the detector electronics, which are present in the inductive coil and electronic components. Normally the detector will operate in the range of 30 to 100 kHz. LD-100 vehicle loop detector parking detectors typically operate at lower frequencies. The effect of this oscillation is the magnetic flux around the loop conductor in the road.

Single Vehicle Loop Detector

When the vehicle moves on the loop and cuts into the magnetic flux, two effects are produced. Ferromagnetic materials, typically found in steel belt tires and smaller engine components, cause transformer action and increase loop inductance. This is called the ferromagnetic effect. The eddy current effect caused by the larger portion of the vehicle chassis and body is opposite to the magnetic field and thus causes the loop inductance to decrease. The eddy current effect usually replaces the ferromagnetic effect. resulting in an overall reduction in loop inductance. The inductance is inversely proportional to the frequency, so a reduction in loop inductance results in an increase in frequency. Thus, by analyzing the positive change in frequency, the vehicle detector is able to sense the presence of the vehicle on the loop. A vehicle will cause an inductance change when moving over a loop. This table shows the typical inductance change over Single Vehicle Loop Detector caused by different vehicle types under ideal conditions. This loop size is characteristic in most parking installations. Inductance change is shown by AL/L (Delta L over L) which symbolizes the percentage change in inductance relative to the inductance with no vehicle present. This percentage reflects the decrease in inductance against the total inductance of the system. A vehicle not shown on this table but is worth mentioning is a bicycle, which causes a very small inductance change of 0.02%, equivalent to the maximum sensitivity setting of LD-100 Vehicle Loop detectors. Inductance changes over a loop can be effectively measured using the LD-100 diagnostic unit.
