A pneumatic load measuring device for vehicles having pneumatic or air suspension systems includes a pneumatic pressure gauge calibrated to indicate the weight of the vehicle. The gauge is installed in the cab of the vehicle, where it is visible to the vehicle operator, and is connected to the pneumatic suspension system of the vehicle. The gauge may be calibrated to indicate the weight of the vehicle supported by the air suspension system, either in pounds or using the metric system. The gauge may be marked to indicate the maximum allowable weight of the vehicle, if desired, and an adjustable scale may be provided for the cargo weight. The zero point of the adjustable cargo weight scale is positioned opposite the empty weight of the vehicle, so both the cargo weight and total vehicle weight are displayed on a single gauge. A visible and/or audible annunciator may be provided to indicate when the maximum allowable weight of the vehicle has been reached during loading of the vehicle. Alternatively, an electric gauge may be used in place of the pneumatic gauge. The electric gauge is connected to the pneumatic suspension system for measuring the load weight on the vehicle via a pressure to electric (e.g., voltage) transducer.
