Field Probe for Electric & Magnetic Field Measurement
WP400-3
-
Wavecontrol presents a new and unique field probe for the measurement of electric and magnetic fields that integrates both E & H sensors within dimensions of only 3 cm². Which makes it unique is that Wavecontrol has managed to add an E field sensor in a basic structure of a classical 3 cm² field probe. It has been possible, therefore, to obtain a 3 cm² field probe without compromising the capability of assessing E and H fields of its 100 cm² big sister, the recognized and successful WP400.

MAGNETOMAT 1.790
-
Foerster Instruments, Incorporated
The MAGNETOMAT 1.790 is a measuring system for the precision detection of magnetic flux density and relative permeability. The MAGNETOMAT software is used for displaying the measured values and saving and exporting data. The wide range of probes facilitates optimal adjustment to the conditions of the application, such as the measurement of relative permeability within the scope of the quality control of stainless steel and low-permeable (non-magnetic) alloys. Further applications include the long-term monitoring of the magnetic environment, e.g. prior to installing magnetically sensitive devices, and the localization of ferrite enclosures in stainless steel and NE materials. Changes in material (sulfidation, degradation of lamination, structural changes) can also be proven thanks to permeability comparative measurements.
