WEIGH-IN-MOTION

PORTABLE WEIGH-IN-MOTION EQUIPMENT

Description

System that measures the weight of each semi-axle, the length and the speed of heavy vehicles running on a road without interrupting the traffic flow.

Technical characteristics

• The weighing system includes a weight sensor, a signal classifier and a data record.
• The weight sensor consists of a little mat, which dimensions are 1800x510x9,5 mm, that is the capacity element of an oscilator circuit. The frecuency changes when the distance between both plates of the mat is reduced, depending on the load of the vehicle axles that pass over it.
• Once each weighing system is placed, the calibration of each system takes place by means of a truck (shown in the picture), of two axles, whith a rear axle of 11,5 tons (standard axle in Spain).

Applications

Campaigns of traffic census and weighing of heavy vehicles obtaining the spectrum of load and the distribution of vehicles in terms of length, types, and speed.
