Product Description

Features:

Two-way output relays
Two outputs of them are unlimited when corresponding loop is permanently covered, while others are multi-mode that can beset by users
Direction detecting function can be used to statistics the vehicle flux
Principle is based on a change in the inductance within loop which is caused by the metallic components of passing vehicles
Changes are picked up and evaluated by microprocessor
Ease of use due to automatic calibration when operating voltage is applied
