The USVD-4X drive thru vehicle detector uses Triangular Planar Array (TPA) technology to detect the presence of a vehicle. The USVD-4X handles any drive thru operation, including fast food, banking, pharmacies, car washes and parking.
For these types of applications, the USVD-4X is much less expensive than traditional vehicle loop detectors, which require the installation of a loop in pavement. The USVD-4X is simply mounted on a post or order box, and aimed at the location where a vehicle would pass to initiate a transaction. No set-up or adjustments required.
The USVD requires 12-24VDC/VAC, and provides a form “C” set or relay contacts indicating vehicle presence. Utilizing TPA technology, the detection head consists of 4 ultrasonic transducers that connect to the internal microprocessor-based control board. The detection head “scans” the expected location for a vehicle and activates its output upon detection of a vehicle.
