Car Park Management Vehicle Traffic Loop Detectors Single Channel
Quick Detail:
vehicle loop detector
Single channel inductive loop detectorsl
Use in car parking system..and so on
Adjustable in 3 increments (high. Medium. Low).
Application
Loop detectors are used wherever vehicles have to be detected. Like
monitoring and safe guarding access ways to counting vehicles. The
output signal can be used for controlling door and gate drive
mechanisms, operating barriers, controlling traffic light systems
in car parks or activating card dispensers in car parks.
The WSTV-410 is a single channel inductive loop detectors. The
principle is based on a change in the inductance within the loop
which is caused by the metallic components of passing vehicles. The
changes are picked up and evaluated by a microprocessor. Ease of
use thanks to automatic calibration when the operating voltage is
applied.
Features:
Reset Switch. Pressing the reset switch enables the detector to be manually
reset during commissioning and testing. This results in the
detector re-tuning the sensing loop and becoming ready for vehicle
detection.
Switch selectable Sensitivity. The detect sensitivity is the minimum change in inductance
required to produce a detect output. (%ΔL/L). Eight sensitivity
settings are available on the switches to allow flexibility in
configuration.
Switch selectable Frequency. The frequency of the loop is determined by the inductance of the
loop and the frequency switch setting. If the frequency switch is
on, the frequency is reduced. It may be necessary to change the
frequency to prevent cross-talk between adjacent loops on different
detectors.
