Remote Indicator Patents (Class 177/205)
  • Patent number: 4106580
    Abstract: This force measuring apparatus includes a balance beam, means for applying a force representative of a load to be weighed to the balance beam, and means for applying counterweights in preselected steps to the balance beam. A signal is picked up from the position of the beam and is used to actuate a display indicating the weight of the load. The balance beam moves within a limited range of positions. Whenever it approaches one end of its limited range, a maximum or minimum signal is produced and controls a motor to drive the counterweight means to apply counterweights to the beam or to remove counterweights, as required to restore the balance beam to its limited range of positions. The display is concurrently reset to compensate for the change in the counterweight, so that the display accurately indicates the weight of the load.
