EP-4 AC Magnetic Field Probe

Product catalog summary

Overview: The document provides technical specifications and usage instructions for AC magnetic field evaluator probes, specifically models EP-102A and EP-102T, manufactured by Magnetic Shield Corporation.

Specifications: The probes are designed to work with digital volt meters or oscilloscopes to identify AC magnetic field sources and measure magnetic shield attenuation. They have a nominal output of 60 millivolts per gauss at 60 Hertz and are accurate for direct measurements up to 3 kHz. The probes are air core inductors sensitive to magnetic flux lines, with a housing diameter of 1-⅜ inches and length of 2-¼ inches. They come with a standard BNC output connector.

Types of Probes:

Axial Probe (EP-102A): Provides maximum reading when aligned with the field along the housing axis.
Transverse Probe (EP-102T): Provides maximum reading when the field approaches the side of the housing perpendicular to the yellow stripe.

Usage: The probes are used to determine interference field intensity, aiding in the specification of appropriate magnetic shielding materials such as MuMETAL®, CO-NETIC®, and NETIC®. They are encapsulated in an epoxy housing for durability and have a shielded cable to prevent loop current pickup.

Additional Information: The document mentions the availability of a BNC to dual banana adaptor upon request and provides a formula for calculating gauss (peak) using the probe's output. The formula is: GAUSS (PEAK) = 60 • E(peak mv) / (Cal. No. • f(Hz)).

NOTE: Probes are supplied with BNC connector. BNC to dual banana adaptor available upon request. Our AC magnetic field evaluator probes may be used with a digital volt meter or oscilloscope to determine AC magnetic field sources and intensities. It is also used to measure the attenuation of magnetic shields. The nominal probe output is 60 millivolts per gauss at 60 Hertz. The formula on the probe label gives the individual probe calibration number and the correction for other frequencies. The probes are accurate for direct measurements in gauss for frequencies up to 3 kHz. At higher frequencies...
