Inductive Loop Sensor Single Channel Precise Detection Built-in Diagnostics

The Inductive Loop Sensor redefines reliability in vehicle detection with its unparalleled precision and self-monitoring capabilities, engineered for demanding environments like toll lanes, industrial gates, and urban intersections. Featuring 16-level sensitivity calibration (0-F), it achieves micron-level accuracy across a broad 15-2000μH inductance range, detecting vehicles from bicycles to heavy-duty trucks while ignoring non-metallic objects like plastic barriers or debris. Its adaptive noise suppression dynamically filters interference from nearby motors, radio towers, and EV chargers, ensuring 99.95% detection accuracy even in high-EMI zones. The sensor’s built-in diagnostics shine with real-time LED indicators for coil health (green = normal, red = short, yellow = open) and a self-test mode that generates automated reports via Bluetooth for proactive maintenance. Encased in a UV-resistant ABS housing (IP65-rated), it withstands extreme temperatures (-30°C to +80°C), corrosive road salts, and prolonged UV exposure, making it ideal for both indoor and sheltered outdoor installations.

Beyond its rugged design, the sensor simplifies integration into modern systems. The universal 12-24V DC/100-240V AC input supports solar-powered and grid-connected setups, while the configurable relay output (NO/NC, 0.5A @ 120VAC) interfaces seamlessly with barriers, traffic lights, and IoT platforms. For smart cities, its Modbus RTU compatibility enables real-time data streaming to traffic management systems (TMS), empowering adaptive signal control and congestion analytics. In a recent pilot at a German logistics hub, the sensor reduced false triggers by 90% and maintenance costs by 40% through predictive diagnostics. Certified for CE, FCC, and RoHS, it also features auto-reset functionality to recover from power surges or transient faults without manual intervention.

From airport tarmacs monitoring ground service vehicles to retail drive-thrus optimizing queue times, this sensor delivers unmatched versatility. For industrial complexes, its precision ensures AGVs navigate safely without misreads, while toll operators leverage its EMI immunity to prevent revenue loss from missed detections. Backed by a 7-year warranty and 24/7 technical support, the Inductive Loop Sensor is the ultimate blend of precision, durability, and intelligence—proving that single-channel solutions can outperform bulkier, costlier alternatives.

  • The compact and well-engineered housing combines all industry requirements for features and functionality, allowing this detector to be incorporated into any existing traffic detection system.

• 3. LED Diagnostic Capabilities
  • Comprehensive diagnostics capabilities enable accurate diagnosis of loop and installation problems and shows through LED, ensuring optimal performance and reducing downtime.

• 4. Selectable Presence Time
  • The output of the presence relay can be selected to limit a detect output to a fixed time (greater than 30 minutes) while a vehicle remains on the loop, providing flexibility in traffic management.

• 5. Loop Presence Time
  • Interference between adjacent loop detectors can be identified through integral indication and eliminated by adjusting the frequency setting, ensuring reliable operation.

• 6. Two Separate Output Relays
  • Presence Relay A: Provides presence output and can be extended for 0, 2, 5, 8, 10, 15, 20, or 30 seconds, programmable with external 10-way DIP switches.
  • Pulse Relay B: Programmable with external 10-way DIP switches, it offers presence, pulse on entry, pulse on exit, or failed output, enhancing detection flexibility.

• 7. Automatic Sensitivity Boost (ASB)
  • This feature reliably detects large truck-trailer combinations and high-bed vehicles by automatically boosting the sensitivity to maximum upon vehicle detection, ensuring accurate identification.

• 8. Automatic Environment Drifting Compensation
  • Loop detectors (or other sensors) automatically adjust and calibrate themselves to changes in environmental conditions, maintaining detection accuracy and stability despite varying weather and environmental factors.

• 9. 10 Dip Switch
  • The dip swich design on the shell makes the setting of loop detector easier and clearer, which is very user-friendly for users. Users can set all the functions first and then install the loop detector.

• 10. Anti-crosstalk interference.
  • Through the dip Switch, the frequency of the loop detector can be adjusted to prevent crosstalk interference caused by the installation of two loop coils too close.
