Vishay Precision Group announced that its VPG On-Board Weighing division has expanded its offering of on-board overload protection systems.

Available kits include the Axle transducer scale system, Trojan suspension-mounted scale system, and the Airscale system for vehicles with air suspensions.

The new systems are compatible with a broad range of truck makes and models - from dump and tow trucks to forestry, refuse and bulk hauling trucks - to eliminate overloading fees at truck scales; for the reduction of vehicle maintenance by preventing overloading; and assisting in disposal site decisions based on the real-time, known weight of the material to be discarded.

The systems display weight with no driver interaction, are accurate to within 2 percent, and provide an unlimited capacity. The kits provide quick and easy installation without disassembly of the vehicle chassis, suspension, or body; feature easy two-step calibration, and are self diagnostic. Weight is displayed on a bright, easy-to-read display mounted in the cab.

The Axle and Trojan transducers are designed to provide gross vehicle weight, net payload weight, and axle group weights. The Trojan system is available for dual rear axle configurations, while the Axle system is available for single and dual rear axle configurations. Both systems can be used with pusher, tag, or lift axles. Axle group weights are provided for both the front and rear axle groups, and rear-only systems are also available.

The Airscale suspension-based weighing system is available for trucks with air suspensions and provides gross or net vehicle weight by measuring the pneumatic pressure change in the suspension as weight is added and subtracted. Axle group weights are provided, as well as gross and net weights. Rear-axle-group-only and front-axle-group-only systems are also available.

All overload protection systems are available with an optional relay board, printer, and handheld remote. Connected through an expansion slot, the relay board allows an audio or visual alarm to be added to the system, in addition to the standard flashing weight reading on the meter's display. Connected via RS232, the handheld remote displays the weight reading when the driver is away from the meter while the printer prints out the time, date, weight, and ID number.
