A payload weight calculation apparatus and method in which a load holder angle measuring apparatus is communicably coupled to a weighing module (100) configured to calculate a weight value representative of a payload weight in respect of a loading machine comprising an arm (7)and a load holder (8) pivotally mounted at a distal end of said arm (7). The load holder angle measuring apparatus comprises an ultrasonic sensor (18) located at a distance from a pivot point between the load holder (8) and the arm (7) and configured to generate a distance single representative of a distance between the sensor (18) and the pivot point (8b) and provide the distance signal, or data representative thereof, to the weighing module (100) for use in the calculation of the weight value. |
