An electronic device for weight measurement in particular in the elevator cars, comprising new and improved weight sensors allowing the moving part of the footboard to be bent under the action of the applied weight without impairing the result of the measurement. Said weight sensors are connected to an electronic exchange provided with peculiar electronic components and circuits adapted to compensate the variations due to mechanical defects or deformations of the elevator car as well as to agents such as temperature, relative humidity a.s.o. which could affect a mere mechanical system. A weighing block device acting when the door is closed prevents wrong measurements due to the movement of the elevator car and/or of the people in the car itself. |
