Applications

The FVM400 Vector Magnetometer is a four line by sixteen character handheld three-axis fluxgate magnetometer. It is a precision instrument for measuring the vector components of weak magnetic fields. All three vector components are displayed simultaneously. Typical applications include

  • Package Inspection
  • Materials Screening
  • Shielding Effectiveness
  • Field Mapping (including position - see below)
  • Magnetic Environment Control
  • Magnetic Moment Measurement
  • Magnetic Signature Determination

Description

The FVM400 uses fluxgate technology to measure the three vector components of the magnetic field. The fluxgate sensors are packaged in a 1" square by 4" 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 mode, the FVM400 displays the thee components of the magnetic field vector. In the Polar Coordinates mode, the FVM400 displays the magnitude and direction of the field vector.

FM300 Software Package

You can remotely control the FVM400 through an RS232 connection to a serial port of a computer. Supplied with the FVM400 is the FM300 Front Panel software package. This package includes the FM300 Front Panel program and the FM300 Network Server.

With the FM300 Front Panel program you can

  • Control all the FVM400 functions.
  • Download the FVM400 data stored in its internal buffer.
  • Strip chart FVM400 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 FM300 Network Server.

Download the User's Manual for a complete description of the FM300 Front Panel program.

With the FM300 Network Server you can

  • Continuously log FVM400 data to a file.
  • Make data available to multiple users over the Internet.
  • Control FVM400 functions over the Internet.

Download the User's Manual for a complete description of the FM300 Network Server.

Download the FM300 Front Panel software package and take it for a test drive. MEDA has set up an FM300 Network Server at fm300.meda.com. After installing the software, use the FM300 Front Panel program to access data from our server. Use the default port number.

MagGPSce Data Logging Program

Now you can log magnetic field and position data simultaneously on a PDA using an FVM400 and a GPS receiver. The program runs under Windows CE 2.11 or greater. and is free. Click here to download the installation program (MagGPSce.exe). Click here to download the manual (MagGPSce.pdf). You do not need to have an FVM400 and GPS receiver to log data. The user can choose to log either type of data or both simultaneously.
