VPG Offers First On-Board Overload Monitoring System With Solid-State Axle Deflection Sensors, for High Durability and Accuracy to 3 % in Vehicles Over 8.3 Tons (7.5 Metric Tons)

MALVERN, PA--(Marketwire - Jan 19, 2012) - Vishay Precision Group, Inc. (NYSE: VPG) today announced that its VPG On-Board Weighing division has expanded its offering to include TruckWeigh, a new overload monitoring and payload maximization system for medium- and high-capacity vehicles greater than 8.3 tons (7.5 metric tons). Designed for easy installation, TruckWeigh is the industry's first such system with a low-weight construction to maximize payload capacity, and solid-state axle deflection sensors with no moving parts to keep the system from slipping out of calibration due to mechanical wear. TruckWeigh delivers the high accuracy, reliability, ease of use, and durability necessary for even the harshest on-board applications.

TruckWeigh combines VPG's patented axle transducer technology and air pressure sensors to protect against overload in vehicles with mechanical and/or air bellows suspension. It is compatible with a broad range of rigid trucks, tractor-trailers, and trailers -- from articulated and rigid tippers to RCVs, skip loaders, roll-offs, and hook loaders -- to maximize payload; optimize fuel consumption; protect against axle and gross overload; avoid fines and overload endorsements; reduce vehicle wear and tear; and minimize safety risks.

The easy-to-use system displays weight with no driver intervention, features up to 3 % accuracy, and supports capacity (GVW) up to 66 tons (60 metric tons). The kit installs quickly and easily into new or existing vehicles without welding and without heavy mechanical assemblies, features easy two-step calibration, and is self-diagnostic. Suitable for both DIN radio slot and dash mount, the TruckWeigh indicator displays the loading conditions of each axle, axle group, and/or complete vehicle. This system also includes trailer identification functionality, negating the need for recalibration every time the trailer is swapped.

For continuous remote monitoring, TruckWeigh can also be linked to third-party-compatible tracking and fleet management systems to relay the vehicle loading condition to the depot. TruckWeigh is available with an optional external alarm sounder, packer plate shutdown, barrier control output, 511 FreeWeigh hand-held remote display unit displaying the weight reading when the driver is away from the meter. Another option is a thermal or heavy-duty printer connected via RS232, with a custom printer header that prints out the time, date, weight, and ID number.

A similar VanWeigh system is available for vehicles under 8.3 tons (7.5 metric tons).
