A weighing scale especially adapted for use as a pediatric or infant scale having a mechanical leverage weighing structure with a high degree of sensitivity and low friction and hysteresis coupled with a compatible electronic measuring system and a digital read-out system is provided wherein a base has a weight responsive movable platform mounted thereon, a housing mounted on the base behind the platform, said housing forming an enclosure extending upwardly substantially higher than the platform with weighing mechanism inside the housing connected through an opening in the base to the platform, the weighing mechanism including a variable inductance transducer which generates a signal in response to weight on the platform and a read-out unit mounted on the top of the housing, said read-out unit displaying weight measurements and being operable in response to said signal.
A weighing scale comprising in combination a base, a weight responsive movable platform mounted on said base, a housing mounted on said base behind said platform, said housing forming an enclosure extending upwardly substantially higher than said platform, weighing mechanism in said housing connected through an opening in said base to said platform, said weighing mechanism including a variable inductance transducer which generates a signal in response to weight on said platform, and a read-out unit mounted on the top of said housing, said read-out unit displaying weight measurements and being operable in response to said signal, and said weighing mechanism in said housing being supported on said base independently of said housing.
A weighing scale comprising in combination a base, a weight responsive movable platform mounted on said base, weighing mechanism including a variable inductance transducer which generates a signal in response to weight on said platform, a read-out unit displaying weight measurements and being operable in response to said signal, and an electrical circuit comprising switch means controlling said signal to said read-out unit, said switch means including a plug and a receptacle for said plug, said plug being connected to a remote normally open momentary switch, said circuit normally passing through said receptacle when said plug is removed from said receptacle and passing solely through said momentary switch when said plug is inserted in said receptacle whereby depressing said momentary switch to closed position momentarily will give an instantaneous reading in a read and hold mode.
