Abstract
23,071. Holden, F. Nov. 25. Electro - magnetic current meters; power meters.-A beam 1 carries at each end a coil 4 moving in the field of a permanent or other magnet 5, and weights 6, 12 are adjustable along the beam and a parallel beam 11 respectively to restore the balance, the effect of the total movement of the weight 12 being equal to that of the movement of the other weight 6 through one division. The beam 1 is preferably of aluminium and made hollow to receive the leads, the weight 6 being attached to a pin which can be inserted in holes. The zero is adjusted by means of an auxiliary weight 14, and the sensitiveness by means of a weight 13. For use as a watt-meter, the permanent magnets are replaced by electro-magnets. In a modification, the magnets are mounted on the beam and the coils fixed.
