Output Relay Vehicle Loop Detector for Temperature Must Not Exceed 65° C

Output Relay Vehicle Loop Detector for Temperature Must Not Exceed 65° C

Quick Detail:

vehicle loop detector

Single channel inductive loop detectorsl

Application

Loop detectors are used wherever vehicles have to be detected. Like monitoring and safe guarding access ways to counting vehicles. The output signal can be used for controlling door and gate drive mechanisms, operating barriers, controlling traffic light systems in car parks or activating card dispensers in car parks.

The PD-123 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.

Features:

1. High temperature stability, used in kinds of environment

2. Environment drifting compensate automatically

3. Multilevel lightning protection

4. With function of sensing loop malfunction automatically (disconnection or cutting-out)

5. Cooperate with barrier gate to realize vehicle anti-hit and automatic close function

6. Detect the vehicles driving direction with two loops
