Vehicle Loop Detector Manufacturers With Relay For Inductive Loop Vehicle Detector

Vehicle Loop Detector Manufacturers 

Shenzhen Noble OPTO.CO., LTD. is a vehicle loop detector manufacturer. Our product range includes expertly engineered vehicle detection loops, surface-mounted vehicle detection loops, and virtual loop detectors.

Applications:

The LD-202 dual loop detector is ideal for any scenario where vehicle detection is necessary. It is commonly used for:

• Monitoring and safeguarding access ways
• Counting vehicles
• Controlling door and gate drive mechanisms
• Operating barriers
• Managing traffic light systems in parking lots
• Activating card dispensers in parking facilities

Product Description:

The LD-202 is a single-channel inductive loop detector. It operates on the principle of detecting changes in inductance within the loop, caused by the metallic components of passing vehicles. These changes are processed and evaluated by a microprocessor. The LD-202 is user-friendly, featuring automatic calibration upon application of the operating voltage.

12VDC Detector with Relay for Inductive Vehicle Loop Detector

Main Features:

1. Reset Switch: The reset switch allows for manual resetting of the detector during commissioning and testing. This process re-tunes the sensing loop, preparing it for vehicle detection.

2. Selectable Pulse Time: This feature lets you set the duration for which the pulse relay is energized, offering options of 1 second or 0.5 seconds.

3. Pulse Relay Selection: The pulse relay can be configured to energize either upon vehicle detection or when the vehicle exits the loop.

4. Sensitivity Boost: This function sets the undetected level to maximum sensitivity, preventing loss of detection for high-bed vehicles.

5. Switch Selectable Sensitivity: With 11 adjustable sensitivity settings, this feature provides flexibility in configuring the detector to suit various requirements.

6. Switch Selectable Frequency: Four frequency settings are available to prevent cross-talk between adjacent loops, ensuring accurate detection.

7. Filter Option: This option introduces a delay between vehicle detection and the activation of the output relay, preventing false detection of small or fast-moving objects.

8. Permanent Presence Option: This feature ensures continuous detection of a vehicle parked over the loop for extended periods.

Components and Installation:

There are two basic components in a driveway vehicle detection system: the loop detector and the loops themselves.

Loop Detector:

• Function: The loop detector is the "brain" of the system, controlling module components installed on the gate operator control or circuit board. It determines the actions taken when a vehicle is detected.
• Installation Methods: There are two installation methods:
  • Plug-in Type: Some gate operators have built-in sockets for plug-in loop detectors.
  • Hard-Wired: Other models require wiring the detector using a harness and connectors.

Loops:

• Types:
  1. Saw-Cut Loop (Cut-in Loop): Installed in existing roadways, these loops are placed in grooves cut into the pavement. Saw-cut loops are available as:
     • Custom-Sized Loop Wire: For creating loops of specific sizes.
     • Preformed Loops: Pre-sized with varying lead-in wire lengths for easy installation.
  • Sealant Requirement: All saw-cut loops need to be sealed with loop sealant to ensure proper functioning and longevity.

Key features of these detectors include manual reset capabilities, selectable pulse times, adjustable sensitivity, frequency settings to prevent cross-talk, and options for permanent presence detection. The flexibility in configuration and ease of installation, whether plug-in or hard-wired, make these detectors suitable for a wide range of environments and requirements.

As a vehicle loop detector manufacturer, Shenzhen Noble OPTO.CO., LTD.'s commitment to quality and innovation ensures that their vehicle loop detectors meet the highest standards, providing reliable and precise vehicle detection for both simple and complex applications.
