Single / Double Channel Inductive Loop Detector Traffic Vehicle Detection High Sensetive

Loop detectors are essential for vehicle detection applications including access monitoring, security systems, and traffic control. The output signals can operate door and gate mechanisms, control barriers, manage traffic light systems in parking facilities, and activate card dispensers.

This direction-detecting loop detector features vehicle flux statistics capability. The system operates by detecting changes in loop inductance caused by metallic components of passing vehicles. A microprocessor evaluates these changes, and automatic calibration occurs when operating voltage is applied for ease of use.

Upon power application, the detector enters self-calibration mode with green LED flashing and red LED off for approximately 1 second. Vehicles should not be present on loops during calibration. After calibration, the green LED stops flashing and red LED remains off. When a vehicle passes over the loop, the red LED illuminates.

DIP1 and DIP2 control sensitivity settings. DIP3 adjusts presence output time for relay 1. DIP4 configures relay 2 for presence/pulse output. DIP5 sets presence signal output time. DIP6 controls frequency settings. Jumper wire connection to open end connects PIN16 to NO of relay 1; connection to close end connects PIN16 to NC of relay 1.

Users can modify loop operating frequency to prevent cross-talk from adjacent loops or environmental frequency interference. Two frequency styles are available, configurable via DIP6.

Sensitivity is adjustable using DIP1 and DIP2 on the front panel. If vehicle detection fails during testing, increase sensitivity settings accordingly.
