Description
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.
