Fluxmeter are measuring instruments for the determination of the magnetic flux Φ.
Magnetic measurement methods can be distinguished in
- Induction methods,
- Force methods and
- Indirect methods.
Fluxmeter contact here at induction methods and are based on the fundamental law of electromagnetic induction.
Principle of operation
The time change of the magnetic flux Φ, which is encompassed by a measuring coil, a measuring voltage induced; the integral of the voltage over time results in the change of the magnetic flux.
A flux change is effected
Method
Fluxmeter can be designed as
- Electronic integrators
- Ballistic galvanometer
- Kriechgalvanometer ( Drehspulfluxmeter )
