Double Channel Car Loop Detector (K-PD232)

Double Channel Car Loop Detector


1.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. 
2. The principle is based on a change in the inductance within? the loop which is caused by the metallic components of passing vehicles. 
3. The changes are picked up and evaluated by a microprocessor. Ease of use thanks to automatic calibration when the operating voltage is applied.
