Single Channel Loop Detectors
PRODUCT DESCRIPTION
One of the most critical components of the whole vehicle access control system is the inductive loop detector. Nortech’s detectors have been renowned for their reliability and durability for many years. Single channel loop detectors are used to identify the presence of vehicles by means of an inductive loop buried under the road. These “single chip” microprocessor-based units benefit from a detect filter and frequency indicator and are suitable for parking control and motorised door or gate applications all detectors are CE tested and approved. A compact detector diagnostic unit is available for extracting data from new and existing sites.
