The FVM4OO Vector Magnetometer is a new four-line by sixteen character display version of the FM3OO Vector Magnetometer (below). Like the FM300, it is a precision instrument for measuring the vector components of weak magnetic fields. The FVM400 will display all three vector components simultaneously.

Typical applications include:

  • Package Inspection

  • Materials Screening

  • Shielding Effectiveness

  • Field Mapping

  • Magnetic Environment Control

  • Magnetic Moment Measurement

  • Magnetic Signature Determination



The FVM4OO uses fluxgate technology to measure the three vector components of the magnetic field. The fluxgate sensors are packaged in a I-inch square by 4-inch long probe that is connected to the handheld electronics unit by a modular telephone cord. The sensor can be located up to 100 feet from the electronics unit. 

In the Rectangular Coordinates mode1 the FVM40O displays the three components of the magnetic field vector. In the Polar Coordinates mode, the FVM4OO displays the magnitude and direction of the field vector.


Software Package

You can remotely control the FVM4OO through an R5232 connection to a serial port of a computer. Supplied with the FVM4OO is the FM3OO Front Panel tm software package. This package includes the FM3OO Front Panel program and the FM3OO Network Server.

 With the FM3OO Front Panel program you can:

  • Control all the FVM400 functions

  • Download the FVM4OO data stored in its internal buffer

  • Strip chart FVM4OO data in real time

  • Save data to a text file for later retrieval or for further processing by, for example, a spreadsheet program like Microsoft Excel

  • Download data over the Internet from the FM3OO Network Server


With the FM3OO Network Server you can:

  • Continuously log FVM400 data to a file

  • Make data available to multiple users over the Internet

  • Control FVM4OO functions over the Internet
