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.

Polarity Tester
PT-1
-
International Electro-Magnetics, Inc.
The PT-1 provides a simple and easy way to determine the relative polarity of coil windings. It allows for an in-process test that takes a minimum of time to perform. By placing a coil on the platform and making connection to the start and end of a winding, a test signal is induced in the winding. The induced signal is low level and completely safe for the operator. By comparing the test signal phase of the coil under the test output, the relative polarity is indicated by the Red/Green LED. The tester operates by inducing a signal voltage in the coil under test by means of a magnetic flux field. The field is generated by a coil located in the probe base. The coil configuration is designed to provide optimum field distribution. We have also applied this basic circuit to a 5-channel scanning unit.

Magnetic Material Test Fixture
16454A
Test Fixture
The 16454A is designed for accurate permeability measurements of toroidal-shaped magnetic materials. Since the construction of this fixture creates one turn around the toroid (with no magnetic flux leakage), the need of winding a wire around the toroid is unnecessary. Complex permeability is calculated from the inductance with and without the toroid. When the E4991A/4291B with option 002 is used as the measurement instrument, direct readouts of complex permeability are possible. In addition, it is furnished with a small and a large fixture to adapt to a wide range of sizes.

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.
