Vehicle Loop Detector with Single Channel Output Relays

Features:

Single channel

Principle based on change in inductance within loop which caused by metallic components of passing vehicles

Changes are picked up and evaluated by microprocessor, easy to use due to automatic calibration when operating voltage applied

Used wherever vehicles have to be detected, like monitoring and safe guarding access ways for counting vehicles

Output signal can be used for controlling door and gate drive mechanisms, road barriers, controlling traffic light systems in car parks or activating card dispensers in car parks
