China Double Vehicle Loop Detector for Parking System

Two-way output relays; Direction detecting function; Adjustable in 3 increments (high. Medium. Low).
It has two-way output relays. Two outputs of them are unlimited when the corresponding loop is permanently covered, while the others are multi-mode that can be set by users. The direction detecting function can be used to statistics the vehicle flux. 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 due to automatic calibration when the operating voltage is applied.
