Field Strength Measurement Device

Restrictions: Only measurable on ferromagnetic materials

Definition

A field strength measurement device is an instrument used to measure the strength of an electromagnetic field at a specific location. It uses a probe to capture the field and convert it into an electrical signal that can be displayed on a screen or stored in a data logger. The field strength measurement device is used in our facility to measure the residual magnetism of workpieces.

Procedure

The measurement of residual magnetism is performed using a field strength measurement device. First, the workpiece is demagnetized to remove any potential interfering magnetic fields. Then, the field strength measurement device is positioned at various locations on the workpiece to measure the magnetic field.

The field strength measurement device captures the magnetic field of the workpiece in the form of magnetic flux densities. It measures how strongly the magnetic field of the workpiece affects the measurement device. The residual magnetism of the workpiece is calculated from the measurement values obtained by the field strength measurement device.

The measurement of residual magnetism is particularly important in the metal industry as magnetic forces can have a negative impact on the processing and quality of workpieces. By measuring residual magnetism, deviations from specified tolerances can be detected and addressed.
