[Specification] PWIM-1 Cardinal High-speed Piezo-based In-motion Vehicle Scale [Description] 
The 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.
