Snow and ice on the undercarriage or on top of a truck or trailer can add several thousand pounds of unwanted weight, reducing legal payload, stressing equipment, and increasing the risk of overweight violations and fines.

TruckWeight's wireless onboard scale, called Smart Scale, can monitor the effects of snow loading. Smart Scale is a wireless onboard scale for trucks, tractors, and trailers with air suspensions. It includes a sensor with antenna, DOT fittings for the vehicle's air line, and a wireless handheld receiver.

The sensor measures temperature and pressure changes in the air suspension and relays data to the handheld receiver using a low-power radio transmitter. A small computer in the receiver interprets the information and provides an axle weight and gross vehicle weight measurement that's accurate to within 150 pounds. It produces readings once per minute, and every three seconds during a 15-minute span when the sensors detect the truck being loaded.

The wireless receiver has a range of 100 feet, allowing readings from the truck cab or loader or while the vehicle is running on the road. Because there are no wires to thread into the cab, most truck operators can install and calibrate the sensors themselves in less than an hour. Smart Scale's weatherproof, shock-resistant, and non-corrosive housing requires no regular maintenance, and the sensors are accurate in temperature extremes ranging from -40° to 158° F (-40° to 70° C) and use common AA batteries.
