Dual Channel Vehicle Detectors
Nortech’s dual channel vehicle / inductive loop detectors have been renowned for their reliability and durability for many years.
Nortech’s dual channel vehicle detectors are used to detect the presence of vehicles by means of two independent inductive loops buried under a road surface. Detectors are available in both boxed and PCB format.
Nortech’s dual channel detectors can be used as an alternative to two single channel detectors to eliminate any presence of crosstalk. They also feature A-B logic to detect the direct of vehicles crossing the loops.
Key Features
- Compact size
- Flexibility – User selectable functions
- 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)
- A-B Logic – for different outputs depending on the vehicle direction
- Visual fault monitor
