Magnet Inspection Tool with High Magnetic and Mechanic Accuracy

By Sasa Spasic, CEO • SENIS AG

Modern magnetic position and angle sensors consist of a combination of a permanent magnet and a magnetic field sensor. Billions of such sensors are built in automotive, industrial and consumer products each year. The characteristics of permanent magnets for such sensors must be carefully controlled. The control of the magnets often includes measurement of the magnetic field over an area or volume of interest near the magnet, which is usually performed by a Magnetic Field Mapper. <read more>

Gaussmeters and Hall Probes for Research and Manufacturing Applications
Versatile benchtop and handheld Hall effect gaussmeters from Lake Shore support a variety of research and industrial applications. In university and commercial research labs, they enable scientists to study the magnetic properties of materials, enabling the development of improved magnetic materials and devices. When used for accurate quality control testing early in the manufacturing or assembly process, these instruments can help companies avoid costly rework at later stages of production.

Applications of Hall effect gaussmeters include:

• validating performance of solenoids
• confirming magnetic field characteristics versus applied current
• mapping a magnetic field shape for a component or assembly
• measuring fringe fields or residual fields, and sorting tested products into groups according to magnetic strength and other characteristics.

These instruments are compatible with Lake Shore Hall probes and allow for both AC and DC magnetic field measurement in most cases. Lake Shore probes are factory calibrated for accuracy and interchangeability. Our experts can recommend or custom design a probe that will ensure the greatest accuracy for your application.

Choosing a gaussmeter: The affordable Model 425 benchtop instrument is effective for most manufacturing operations. However, the Model 460 may be the best solution for mapping surface and volumetric magnetic fields. For advanced research measurements using filtering with fast pulse applications, choose the top-of-the-line Model 475. For a low-cost manufacturing solution, the handheld Model 410 is ideal.
