Abstract
Disclosed is a device for detecting the weight of an article by measuring the amount of pressure required to support the article. The weighing device is characterized by a weighing table having a plurality of apertures for receiving compressed air. The pressure required to support the gross weight of an article passing over the apertures is sensed by a pressure transducer and translated into an electrical signal used to derive the actual numerical weight of the article.
