On Board Weighing Systems used in forklifts and front end loaders are usually hydraulic based using a pressure transducer fitted into the hydraulic lines to provide a pressure reading which is translated into a weight reading by a digital weight indicator The pressure in the lifting cylinder is tapped at a location where the bucket will be parallel to the ground to achieve repeatability. The low level signal from the pressure sensor is amplified and filtered by the high precision monolithic A/D converter and converted into digital format. With the aid of pressure and position sensors, the electronics evaluates complex dynamic weighing calculations to easy to read data shown on a large TFT colour display screen, all in real time. The dynamic weighing feature allows for weight measurements to be carried out even whilst the vehicle is in motion, preventing the need for lifting operation to be momentarily stopped The digitized data is further processed and stored according to the customer need and application.
