Onboard Weighing: Master the Last Critical Tonne.
Overload protection and payload optimization mounted on the vehicle itself — from panel vans to 50-tonne road trains. A global leader in onboard weighing, with more than 35,000 VanWeigh® and TruckWeigh® systems installed worldwide.
Full Payloads. No Overloads. Every Journey.
VPG Onboard Weighing specializes in high-accuracy weighing systems mounted directly on commercial vehicles. The moment a vehicle approaches its legal limit, the system knows — protecting operators from fines and roadside infringements while letting them load right up to the safe maximum on every trip. Fewer journeys, less wear, lower fuel burn, full compliance.
From overload protection on light commercial vans to trade-approved pay-by-weight systems on refuse fleets, OBW solutions are engineered for OEM design-in and retrofit alike — sold and serviced through direct offices and a global dealer network, with R&D in the UK and USA.
And the market is moving toward OBW: administrations worldwide are writing overload detection and onboard mass monitoring into law and enforcing it with technology. Real-time load data, on the vehicle — in a world of real-time data.
Patented Inclinometer Technology: Precision Exactly Where the Law Draws the Line.
An onboard weighing system doesn't need to be a weighbridge. The fines, the safety risk and the wasted payload all live in one narrow window: the approach to the legal limit. OBW's patented inclinometer technology is purpose-built for that window — engineered for high accuracy across roughly 80–110% of gross vehicle weight, the span where overload protection and payload optimization are actually decided.
Instead of inferring weight from spring deflection like conventional systems, the inclinometer transducers measure the change in chassis attitude as the vehicle is loaded — per axle, so an unevenly distributed load shows up just as clearly as an overweight one. No load cells in the load path, no moving parts, nothing to wear or stretch, no recalibration — ever. It mounts to any suspension type, coil, leaf or air, on any number of axles, and it's the only technology of its kind on the market. Body builders fit it in about two hours, calibrate in thirty minutes, and forget it's there.
Around the world, overload enforcement is moving from spot checks to systematic, technology-based regimes — and onboard systems are written into the rules:
Since May 2021, Directive (EU) 2015/719 obliges every member state to actively identify likely-overweight vehicles — using road sensors or onboard weighing equipment — and report check results to Brussels every two years. Implementing Regulation (EU) 2019/1213 standardizes onboard weighing equipment for remote enforcement readout.
The NHVR's Smart OBM regime makes type-approved onboard mass systems a condition of road access for high-productivity and higher-mass-limit vehicles, paired with mandatory telematics — extended to further vehicle classes and states (Queensland and South Australia from January 2027). Chain-of-Responsibility law makes everyone in the supply chain accountable for mass compliance.
Weigh-in-motion screening networks, direct-vision and roadside digital enforcement are scaling across North America, the UK and Asia. Wherever axle-weight rules gain teeth, the economics flip: an onboard system stops being an accessory and becomes the operating license for full payloads.
EDOC & In-House Load Cells: Built for Road Salt, Mud and Decades of Duty.
Where applications call for load-cell precision — refuse bodies, logging bunks, fifth wheels — OBW's US brands run on cells designed and built in-house: Vulcan Super-Beam™ and SI Titan II, finished in VPG's proprietary EDOC electrodeposited organic coating. EDOC passed the ASTM B-117 1,000-hour salt-spray test with no evidence of corrosion and has logged zero coating defects in 15 years of harsh-environment service.
It's the same vertical integration that defines VPG Force Sensors: strain gage, load cell, coating and instrumentation — every element designed, manufactured and supported by VPG.
VPG Onboard Weighing serves customers worldwide. In North America, two specialist brands extend the family with deep roots in their industries:
US-built onboard scales since 1984 — the trusted name in refuse, aggregate and general trucking. Front Fork Scales for refuse loaders, Super-Beam™ load cells with EDOC, and VSL electronics that let fleets mix and match tractors and trailers freely.

OBW systems earn their keep with body builders and fleet operators who install them by the hundreds per year — and measure success in years without an issue. In 2025, Dennis Eagle, one of the world's leading refuse collection vehicle manufacturers, recognized VPG Onboard Weighing with the Gold Award in its inaugural Supplier Recognition Awards.
"Clarks has so far installed VanWeigh in over 2,000 vehicles… Operationally, VanWeigh has been a success."
"We have installed BulkWeigh as an OEM option for over 10 years… over 350 systems per year. Easy to install and very reliable."
"We have had zero operational issues with VanWeigh in three years… no driver interaction required."
Across every market, VPG Connect links onboard weighing to the connected fleet — streaming live load data and alerts to mobile devices and telematics platforms, so the weight on the axle becomes data in the operation.
