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

- 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.

❀Sensitivity Selection
Sensitivity and frequency of the loop can be adjusted by 7-way dip
switch and 10-way dip switch setting.
User can select 8 different setting by changing the setting of the
dip-switch to different modes as in the dip-switch setting tables below. Dip switch 6, 7 and 8 for CH1
sensitivity selection with 0.8 being the least sensitive and 0.015
being the most sensitive.
Dip switch 3, 4 and 5 for CH2 sensitivity selection with 0.8 being
the least sensitive and 0.015 being the most sensitive.
