Electrical parameter i.e. current, determining device, has additional piezoelement provided for causing current flow, which is evaluated for determining electrical parameter in particular for current measurement

摘要

The device has a piezoelement (20) that is coupled to a measuring signal during current measurement performed by a measuring device (14), and is provided as sensory element. An additional piezoelement (22) is provided on which mechanical pressure produced based on the signal is exerted by using a mechanical coupling device (24). Current flow that is caused by the piezoelement (22) is evaluated for determining of an electrical parameter in particular for current measurement. An independent claim is also included for a method for determining of an electrical parameter with a sensory element.
