Product Description

GD100 – Single Channel Loop Detector

The GD100 is a cost effective, single channel, din-rail mounted microprocessor based detector. The product detects vehicle presence by means of an inductance change caused by the vehicle passing over a wire loop buried under the road surface. With front panel switches to allow for different loop frequency settings, sensitivity settings and mode settings.

Applications

  • Parking barrier control.
  • Vehicle access control.
  • Motorised gates and doors.
  • Industrial control systems.

Specific Features

  • Compact Size: This compact industrial housing combines all of the industry requirements regarding features and functionality and allows this detector to be incorporated into any new or existing vehicle detection system. 
  • Selectable Fail-Safe / Fail-Secure: Allows a selectable output for either Fail-Safe or Fail-Secure operation.
  • Loop Isolation Protection: The loop isolation transformer provides protection against lightning and transient damage and allows for operation with single point to ground sensor loops.
  • Loop Frequency Indication: The possibility of cross-talk (interference) between adjacent loops/ detectors can be determined by a visual display, and eliminated by changing the frequency settings.
  • Automatic Sensitivity Boost (ASB): Facilitates the reliable detection of all vehicle combinations and high-bed vehicles by boosting the sensitivity to maximum after detection of a vehicle.
