DC Magnetic Flux Leakage Testing
ROTOMAT / TRANSOMAT Product Family
Foerster Instruments, Incorporated
With the new generation ROTOMAT DA and TRANSOMAT DA flux leakage test systems FOERSTER is setting new standards in continuous quality assurance of ferromagnetic steel tubes. The test systems enable the reliable detection of natural and oblique defects, regardless of their angle or length, in addition to standardized longitudinal and transversal defects. The miniaturization of sensors together with highly integrated electronic components dramatically increases the number of channels. This makes a more precise and finer scan of the surface possible, giving a more complete set of information regarding detected defects. The newly introduced C-Scan visualizes these defects in high-definition and real-time, resulting in a completely new evaluation of the tubes to meet rising quality requirements.

Fluxmeter
480
The Model 480 is a laboratory grade fluxmeter, for use with a Helmholtz coil or custom search coils. This instrument measures the total flux of a magnet part, which can be related to the magnetic field strength. Applications include magnet testing, magnetizing, and automated field measurement. In order to provide accurate and repeatable measurements, automatic or manual drift compensation is available to the user. A peak mode allows even the fastest magnetic pulse, such as those from a magnetizer, to be accurately measured. The Model 480 is also useful for measuring AC fields that are too high in frequency for a gaussmeter to detect. Relay outputs and an external reset input allow for simple automation functions to be implemented, while the RS232C and IEEE-488 ports permit advanced control of the fluxmeter via a remote computer or automation equipment.

Fluxmeters
Flux meter has been the established standard for the measurement of magnetic flux density for determining total flux in a magnet or magnetic assembly. Its use was curtailed except in a few specialized areas because of many factors such as the difficulty in setting up light beam flux meter or ballistic galvanometers, limitations on the ohmic resistance of search coils, the requirement of some degree of operator skill in reading the flux meter etc. The development of the integrating type Digital Flux meter has virtually cancelled the hitherto negative aspects of fluxmeterology and has found a broad niche for many magnetic measurement applications.

Magnetic Field and Permeability Measurement
MAGNETOSCOP® 1.070
Foerster Instruments, Incorporated
The MAGNETOSCOP 1.070 is a portable magnetometer system with microprocessor and probes for measuring the magnetic flux density as an absolute or differential value (gradient). It has a USB port for simple data transfer and an SD card for saving measurement data and parameters. The measuring system also facilitates the recognition and saving of peak values and the adjustment of thresholds for limit values. The unit can be used for series and individual measurements. The data can be easily analyzed and documented with the PC software included in the scope of delivery. The MAGNETOSCOP 1.070 thus facilitates the portable and fast measurement of the relative permeability within the scope of the quality control of stainless steel and low-permeable (non-magnetic) alloys as well as the localization of ferrite enclosures. Changes in material (sulfidation, degradation of lamination, structural changes) can also be proven thanks to permeability comparative measurements.
