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 ULTRA 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 ULTRA 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.
