Truck scale is used to weigh those objects which are loaded in truck. Truck scales can be used in mines or quarries, recycling and bulk liquid and powder movement. It is built from steel or concrete. Modern devices use strain gauges which connect to electronic equipment to totalize the sensor inputs. If the weight of the goods is known it will be quick and easy way to measure the flow of bulk goods in and out of different locations. They are two ways to determine the correct loaded weight-in ground scale and on board scales.

There are four types of on board scales are load cell scales, air-suspension PSI gauges, air-suspension load scales, electronic scales with PSI sensors, and non-load cell scale. Non load cell scale is used in mechanical, spring suspensions. Air-suspension PSI gauges are used in commercial trucks and semi-trailers. Load cell scales are used in payload scales for vehicles with spring suspension.
