Introducing the IRD SAW III portable dynamic scale system

International Road Dynamics’ (IRD) durable IRD SAW III portable wheel load weigher is now available for dynamic weighing; its user-friendly software enables users to efficiently pre-select overloaded trucks. Two IRD SAW scales are paired and connected to a PC via Bluetooth. When a vehicle drives over the scales at slow speed, the weighing result, wheel/axle weights and gross vehicle weight, is displayed on the screen. For weight enforcement with the highest accuracy the system can be switched to static oper

69 International Road Dynamics’ (IRD) durable IRD SAW III portable wheel load weigher is now available for dynamic weighing; its user-friendly software enables users to efficiently pre-select overloaded trucks.


Two IRD SAW scales are paired and connected to a PC via Bluetooth. When a vehicle drives over the scales at slow speed, the weighing result, wheel/axle weights and gross vehicle weight, is displayed on the screen. For weight enforcement with the highest accuracy the system can be switched to static operation mode. Computer-0based processing provides reporting, ticket printing and ticket archiving.

The system enables high vehicle throughput, especially when using two sets of IRD SAW scales, one set in dynamic mode for pre-selection and one in static mode for weight enforcement.

The low profile unit is designed to meet OIML R134 and it lightweight, rugged and corrosion resistant and suitable for twin tyre weighing.
