摘要:
Electromagnetic load compensation weighing apparatus including a temperature correction circuit having a temperature-responsive element mounted in heat sensing relation relative to the permanent magnet, characterized by the further mounting of a component of the compensating current supply circuit in heat-responsive relation relative to the permanent magnet. A Zener diode serving as a reference voltage device in the compensating current supply circuit is preferably the component that is mounted, together with the temperature-responsive element, in heat conducting relation in a common bore contained within the permanent magnet.
