Nortech’s single channel vehicle / inductive loop 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.
Detectors are available in both boxed and PCB format.
A compact detector diagnostic unit is available for extracting data from new and existing sites.
Features
-
Compact size
-
Diagnostic capabilities (when used with a DU100)
-
Selectable permanent presence (to eliminate premature barrier / gate closure)
-
Loop isolation protection
-
Loop frequency indication (to eliminate interference with adjacent loops)
-
Automatic sensitivity boost (ASB) – for reliable detection of high-bed vehicles (e.g. lorries)
-
Detect filter – for screening out unwanted inputs.
-
Powerfail memory (optional) – to retain presence when power is restored.
