STRONGWEIGH SYSTEM COMPONENTSHow StrongWeigh Works
The Control Box is the brain of the Strong Weigh system. It coordinates every sensor and communicates with the vehicle operator.

The Control Box is the heart (or brain) of the Strong Weigh system. One is needed for every truck or tractor, as it communicates with every wireless sensor as well with the operator (via cell phone, tablet, or the StrongWeigh Wireless Display). The Control Box is small (approx. 4.5″ X 3.5″ X 1.25″) and installs near the cab of the truck, typically in the chassis frame. Includes a cable to plug into the truck’s diagnostic port (for power and ECU communication). The Control Box can handle simultaneous communication with more sensors than any truck would need (7), and you can easily swap out your trailer and connect the new trailer’s sensors with the press of a button. Plus it includes integrated GPS, accelerometer, and data logging functionality.
Wireless Deflection Sensor
StrongWeigh’s trump card. Highly accurate. Fully wireless. Easy-to-install. Unquestionably the best deflection sensors on the market.

StrongWeigh’s trump card. These highly accurate, fully wireless, easy-to-install deflection sensors put StrongWeigh ahead of all other scale systems. Our expert knowledge and refined manufacturing techniques allow Strong Industries to produce scales that are better and cheaper than our competitors
One of these sensors is installed on the front steer axle of every truck or tractor, and possibly also on the rear axles and/or trailer axles, depending on the suspension types. The Wireless Deflection Sensor is needed for any axle or suspension that isn’t air ride: Walking beam suspensions require two sensors, and leaf spring suspensions require one or two. With our Easy Clamp system, the Wireless Deflection Sensor quickly and easily installs on most axle beams, walking beams, or trunnion tubes. Weldable brackets are available for special cases.
Wireless Air Pressure Sensor
These highly accurate sensors are used on air ride suspensions. Most air-ride systems use a common line and thus only require one sensor.

This sensor is used on air ride suspensions. It tees in to the pressure line that feeds the air springs of the suspension, and for the typical tandem air ride suspension requires only one sensor for both axles because the air springs are pressurized from a common line. For some air ride suspensions the air springs for the two axles are pressurized independently (usually so that one axle can be lifted when not needed), and in such cases two sensors would be needed, one for each axle.
The typical straight truck, like this tandem dump truck in the illustration, requires only three or four components installed to get the StrongWeigh system up and running. Every truck starts with the Strong Weigh Control Box, which you install in the truck frame near the cab of the truck, and connect to the truck’s diagnostic port. Additionally, every truck needs a Strong Weigh Wireless Deflection Sensor on the front steer axle.
As for the rear axle(s) of your straight truck, the type and quantity of sensors depends on the suspension type: Air ride suspensions use the Strong Weigh Wireless Air Pressure Sensor, which easily tees into the air line that supplies the suspension’s air bags. For typical air ride suspensions, all of the air bags share a common air supply line, and thus require only one Wireless Air Pressure Sensor. However, some air ride trucks are configured with each axle having it’s own air supply, usually so that one axle can be lifted when not needed, and in this case one Wireless Air Pressure Sensor is required for each axle.Walking beam suspensions, like the Hendickson Haulmax suspension for example, use two Wireless Deflection Sensors installed on the walking beams – one sensor on the driver side and one on the passenger side. Leaf spring suspensions on drive axles will typically have one Wireless Deflection Sensor installed on the trunnion tube.
The StrongWeigh Onboard Scale System works on virtually any type of tractor-trailer combination. On the tractor, install the StrongWeigh Control Box, a wireless sensor on the front axle, and one or two wireless sensors on the rear tandem axles (depending on the suspension type). Then, for each trailer, install one or two wireless sensors on the trailer’s axles (again, the number and type of sensors depend on the type of suspension on the trailer). If you have one tractor truck with several trailers, or a fleet of tractors and trailers that regularly switch tractor-trailer pairing, StrongWeigh system works wonderfully: When a tractor hitches to a new trailer, there’s no moving any equipment or disconencting and connecting any wires. From the StrongWeigh app on his/her cell phone, tablet, or the StrongWeigh Display mounted inside the cab, the operator simply selects which trailer is currently hitched, and the StrongWeigh system on the tractor immediately pairs up with the sensors on that trailer.
Uncommon Truck Designs
StrongWeigh can be configured to work for many different kinds of vehicle designs. If you have an unlisted, uncommon, or unique vehicle design we can work together to make StrongWeigh work for you.
