Messapparatur zur genauen punktweisen bestimmung grossflächiger magnetfelder

The principle underlying the method of automatic measurement of air gap flux densities is discussed. With this, a search coil is used and the voltage by time area is converted into a sequences of pulses in a voltage frequency transformer. An after-connected counter effects indication of the voltage by time area in decimal form. The measuring program can be punched in digital form on a tape. The accuracy obtainable as well as the various sources of errors are dealt with.
