[Specification] QWIM-2 Cardinal High-speed Quartz In-motion Vehicle Scale [Description] 
Cardinal’s QWIM-2 High-Speed Quartz In-Motion Vehicle Scale utilizes four 1.5 m long Kistler LINEAS© quartz sensors embedded in the pavement to accurately measure the axle weights of passing vehicles. This scale model uses two more sensors than the QWIM-1 which provides improved accuracy and sensor redundancy. Using the sensor signals, this precision scale is able to measure the axle spacing and vehicle speed. The scale produces a vehicle weight record that includes the vehicle axle weights, gross weight, speed, axle spacing, vehicle classification, time and date and vehicle record number. When properly installed in pavement meeting basic requirements, the QWIM-2 will meet or exceed performance requirements for a Type 3 In-Motion Scale as defined in ASTM E1318-09. This scale is perfect for weighing vehicles travelling at speeds up to 80 mph. The flush mounted sensors offer no obstruction to passing snow plows and are stable over temperature. The scale can be installed in one or more lanes, normally in one day with only an 8-hour lane closure.
