The Smart Scale, from TruckWeight Inc. in Halifax, is the company’s next generation of wireless onboard weigh scale for trucks, tractors, and trailers with air suspensions. It uses sensors to measure temperature and pressure changes in a vehicle’s air suspension and wirelessly relays this data to a handheldreceiver using a low-powered radio transmitter. The sensors produce an axle-weight and gross-vehicle-weight measurement that’s within 0.3% of the actual gross vehicle weight. the company says. The wireless reader allows drivers to take a measurement where it’s convenient and safe, whether that’s in the truck cab or the loading machine. Among Smart Scale’s new features is an automated rapid-response mode which provides one weight measurement every three seconds during a 15-minute span when the sensors detect the vehicle is being loaded. The feature meets the needs of pit and quarry operations, refuse haulers, and others who need fast, frequent readings while loading. During regular use, the system produces a new measurement once per minute. Most truck operators can equip a typical tractor-trailer unit in the field in about 30 minutes, TruckWeight says. With no wires to hook up, the cost of a complicated installation is eliminated, as are maintenance concerns related to cables and electrical connections. Smart Scale’s waterproof, weatherproof, shock-resistant, and non-corrosive housing requires no regular maintenance; the sensors use common AA batteries, which last 8 to 12 months in regular use. Smart Scale has a suggested list price of US$438 for each sensor and $450 for the handheld receiver. Upgrades are available to customers with existing TruckWeight wireless scales. Call 1-877-757-7888.
