Overview of the ULTRA-II Vehicle Loop Detector
The ULTRA II vehicle loop detector is a compact, energy-efficient design with a user-friendly, detachable 7-pin terminal block that simplifies set-up.
This vehicle loop detector provides a relay output indicating vehicle presence or pulse on entry. The ULT-II also has an option for automatic sensitivity boost (ASB) which causes the sensitivity to increase following initial detection. This feature is useful to prevent dropout when detecting high-bed vehicles.
The ULT-II is easy to install and operate. Sensitivity selection is simplified by the ULTRAMETER™ display. Ten sensitivity settings allow for finer adjustment of the detection level, and four frequency selections help to prevent crosstalk in multi-loop applications.
