Dual Channel Vechile Loop Detector
Model: GM-705B
Double Channesl Vehicle Loop Detectors for Parking Lots
The principle is based on a change in the inductance within the loop which is caused by the metallic components of passing vehicles. The changes are picked up and evaluated by a microprocessor. Ease of use thanks to automatic calibration when the operating voltage is applied.
