    The microprocessor takes samples of the output of each load cell many times a second. If the load cell outputs are within the expected range, they are added to obtain total weight per unit of belt length. Belt speed is determined by sampling the output of a tachometer attached to the motor shaft, multiplied by a calibration factor to convert it

  • Weight-sensor calibration for gravimetric coal

    12-10-1982· Another object is to provide a mechanism of reduced complexity for applying a test load for calibration purposes to a gravitmetric coal feeder weighing mechanism. Still another object is to transfer a test load from an independently supported condition within a gravimetric coal feeder enclosure to a calibrating position where it is supported by a weight-sensing mechanism.

    Trucks, aircraft and trains all need periodic weighing. This is done using load cells. A load cell employs either strain gauges where a measurable change in resistance occurs as the material is deformed or piezo materials that produce electrical charge when under pressure. These signals are amplified and can yield readings accurate to ±1%.
