Red Automatic Barrier Gate Vehicle Loop Detector Exist Pulse

One channel vehicle loop detector for automatic barrier gate Functional description The TLD-110 is a single channel inductive loop detectors. 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. Loop Installation The loop(heat-resisting Teflon wire)is
