The innovative ZELT inductive loop sensor invisibly counts vehicles in mixed vehicular traffic with an accuracy of +/-5%.  The system is ideal for permanent or temporary traffic counting.

 

 

Applications include vehicle counting on asphalt or unmade roads and vehicle counting at a car park entrance. Using an inductive loop inserted in the road at a depth of 2-5cm, the Zelt vehicle monitor detects the electromagnetic signature of each vehicle as it passes goes over the loop.

 

Loops are 1.5 m long, and up to four loops may be joined together; because they are inserted in the road, the sensors are almost completely invisible, reducing the risk of vandalism. A 7.2V lithium-ion battery provides trouble free operation for up to a year.

 

Developed, tested and patented by the CETE Sud Ouest in 1999, the Zelt vehicle monitor was adapted and validated by Eco-Counter.



Power consumption:

The Zelt vehicle monitoring sensor is delivered with a 7.2V lithium battery for a battery life of 1 year for one or two loops. A 6V alkaline battery can also be used for a battery life of 6 months. The loop could also be powered by mains electricity. A flashing light indicates when the battery has reached a critical level.

 

Sensitivity:

All cars that have metal in the wheel frame (almost all models).  Some slow moving two-wheel motorised vehicles might be omitted from the count.

 

Accuracy:

5% depending on the quality of the installation and the type of flow.

 

Settings:

Sensitivity and timer are set in the factory.

 

Installation:

Allow between one and two hours to install one loop on an asphalt road.

 

Ground preparation:

The sensor is connected to the logger by 4m of cable (other lengths available on request). Power cutters (diamond disk) must be used in order to cut the asphalt.  A trench is also required for cable and post for the cabinet.
