QWIM-1 Cardinal High-speed Quartz In-motion Vehicle ScaleCardinal’s QWIM-1 High-Speed Quartz In-Motion Vehicle Scale utilizes two 1.5 m long Kistler LINEAS© quartz sensors embedded in the pavement to accurately measure the axle weights of passing vehicles. 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-1 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.
QWIM-2 Cardinal High-speed Quartz In-motion Vehicle ScaleCardinal’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.

The scale can be installed in one or more lanes, normally in one day with only an 8-hour lane closure.
SWIM-1 Cardinal Slow-speed Load Cell In-motion Vehicle ScaleThe Cardinal SWIM-1 consists of a welded steel weighbridge supported by four 50,000 pound capacity stainless steel compression strain gauge load cells and is used to provide accurate axle weights at slow speeds up to 10 mph. The Cardinal Model 825 weight indicator measures each axle weight as the vehicle crosses the platform then displays each axle weight and the gross vehicle weight. If desired, the scale can be used in a static mode for increased accuracy. Equipped with optional axle sensors, the scale can also measure vehicle speed and axle spacing to determine classification. This scale model is commonly used in the dynamic mode to identify over weight vehicles the used in the static mode for enforcement weighing. The Cardinal SCA series load cells used in this scale have been used successfully for over 25 years in full-length Cardinal truck scales and the combined 200,000 pound capacity of the load cells ensure that it’s up to the task of weighing any over-the-road vehicle.
PWIM-1 Cardinal High-speed Piezo-based In-motion Vehicle ScaleThe Cardinal PWIM-1 is a single lane in-motion scale using two full-length piezoelectric WIM-grade axle sensors. This scale uses the same CVM Series Cardinal In-Motion Scale used in our higher performance QWIM series of in-motion scale. Included with the PWIM series scale is a pavement temperature sensor to compensate for the changes in output of the piezoelectric sensors with temperature. This scale provides axle weight, gross weight, axle spacing, speed, vehicle number and time and date for each passing vehicle. The accuracy of this scale is less than that of the QWIM series providing a typical error of +/- 20% on a single axle. Axle group weights and gross weight errors are better.
CWSPS Cardinal Weigh Station Package For Commercial Vehicle EnforcementThe CWSPS package includes both a multi-platform static vehicle scale, a high-speed QWIM series in-motion vehicle presort scale, traffic control system including lane direction lights and loop sensors with automatic and manual operating modes, a remote scoreboard display to show the driver his vehicle’s gross weight and a computer with special application software to integrate the whole system. While you have your choice of static scales, we highly recommend the concrete decked, multi-platform Guardian hydraulic vehicle scale. This heavy duty scale is scale of choice for enforcement weighing because of its fast operating speed, complete immunity to lightning and water damage, lifetime load cell warranty and a wide choice of weight indicating instruments and optional peripherals. The QWIM series in-motion vehicle scale is used to identify over weight vehicles as they enter the station and direct only those that exceed weight preset limits or are randomly selected to the static scale. The others are directed to return to the main roadway. A PLC-based traffic control system ensures accurate tracking of vehicles and provides both automatic and manual operating modes. A PC is included to display both weights from the static and in-motion scale and to administer a database of vehicle records and print associated reports. A wide variety of optional peripherals are available to meet most any requirement.
