Two Channel Loop with Fault Alert | Reliable Operation & Anti-crosstalk interference

In critical access control, traffic management, and industrial automation systems, reliability isn't just a feature – it's essential. System downtime means disruption, potential safety hazards, and increased operational costs. The JUTAI Two-Channel Loop Detector is engineered from the ground up for dependable, continuous operation, incorporating intelligent fault alerts and robust anti-interference technology to keep your systems running smoothly and predictably.

Proactive Maintenance with Integrated Fault Alerts

Troubleshooting loop detector issues can be time-consuming and frustrating. The JUTAI Two-Channel Detector simplifies maintenance with its built-in fault alert system. Integrated diagnostic capabilities, often indicated by clear visual LEDs, provide immediate feedback on the status of the connected inductive loops. Technicians can quickly identify potential problems like loop shorts, open circuits, or significant inductance changes without extensive testing. This proactive diagnostic feature drastically reduces troubleshooting time, minimizes system downtime, and allows for swift, targeted maintenance, ensuring your operations remain efficient. JUTAI empowers you with the information needed for effective upkeep.

Stable Performance Free from Interference

Installations often involve multiple loops operating in close proximity, or environments with significant electrical noise, creating the potential for crosstalk and interference. This can lead to missed detections or false triggers, compromising system reliability. The JUTAI Two-Channel Loop Detector directly addresses this challenge with advanced anti-crosstalk interference technology. Featuring capabilities like adjustable operating frequencies, the detector allows installers to select distinct settings for each channel or adjacent detectors. This minimizes the chance of interference, ensuring signal integrity and delivering stable, accurate vehicle detection you can consistently rely on, even in complex or electrically noisy environments.

Engineered for Dependable, Long-Term Operation

Reliability is more than just individual features; it's embedded in the core design. JUTAI combines the benefits of fault alerts and anti-interference technology with robust engineering and high-quality components. This commitment ensures the Two-Channel Loop Detector delivers consistent, reliable performance year after year, under demanding operational conditions. From secure gate access to complex traffic intersections, you can trust JUTAI detectors to provide the dependable operation necessary for seamless integration and sustained performance within your critical systems.

Choose Reliability, Minimize Downtime

Invest in operational certainty with a loop detector designed for stability. The JUTAI Two-Channel Loop Detector with fault alerts and anti-interference technology provides the peace of mind that comes with reduced downtime, easier maintenance, and consistently reliable performance.

Feature

• 1. 15-2000 μh detection Range
  • The loop detector supports a wide detection range from 15 µH to 2000 µH, accommodating various loop sizes and configurations for versatile application in different traffic detection scenarios.
  • The wide detection range enables our loop detector to detect all kinds of vehicles, motorcycles, cars, Ultra long truck, buses and so on

• 2. Compact Side
  • 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. Diagnostic Capabilities & LED Indication
  • Comprehensive diagnostics capabilities enable accurate diagnosis of loop and installation problems and shows through the LED state, 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. 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.

• 6. 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.

• 7. 17 Dip Switch Setting
  • 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.

• 8. Dual Channels work Cooperatively or Independently
  • Dual channel loop detector can be used as two single channel versions, Supports two independent detection channels.
  • Also allowing for the simultaneous monitoring of multiple loops, loop detector has the ability to recognize direction in single-channel applications. enhancing the flexibility and accuracy of vehicle detection.

• 9. 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.
