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 normally buried in a parallelogram form gap. After the test, seal the gap with liquid pitch. 1 to 2 circles of loops should be added as compensation when there are metal things under the ground. And the inductance should be kept at 150-300uH.The lead time must be twisted together closely, so as to prevent the disturbance caused by shock.
