Double Channel Vehicle Loop Detector with High Sensitivity and
Environment Compensation for Vehicle Detection
Product description
LD-600 is used for wherever vehicles have to be detected, for
example for monitoring and safe-guarding access ways or for
counting vehicles. The output signal can be used for controlling
door drive mechanisms, operating barriers, activating card
dispensers etc.
Double Channel Vehicle Loop Detector Highlights
- High-temperature stability, used in kinds of environment
- High sensitivity adjustable range
- Environment drifting compensate automatically
- Multilevel lightning protection
- With the function of sensing loop malfunction automatically
(disconnection or cutting-out)
- Cooperate with barrier gate to realize vehicle anti-hit and
automatic close function
- Detect the vehicles driving direction with two loops
Double Channel Vehicle Loop Detector Function & feature
Vehicle detector is a ring for single induction coil buried digital
intelligent metal detector is mainly used to detect vehicles and
metal objects.

Loop installation method
After determining the loop geometry, a groove (5-8 mm wide, 30-50
mm deep) must be cut in the floor for installing the loop. We
recommend cutting an inclined groove (45° angle) at the corners of
the loop. Routing the loop wire along this incline will protect it
from excessive wear at the corners. The groove must then be cleaned
avoiding any kind of moisture. Run the loop wire as tight as
possible along the very bottom of the groove.
