These compact, high performance fluxgate sensors with integral electronics provide precision measurements of static and alternating magnetic fields in three axes.
They are available in a variety of enclosures. Powered from any ±12V supply, outputs are in the form of three analogue voltages from 0 to ±10V, proportional to Bx, By and Bz.
The sensors have a very wide range of applications in physics, bioelectromagnetics, geophysical exploration,and defence
A range of power supply and data acquisition units are available
| Product name | Package | Noise specification* | Range in μT |
| Mag-03 | MC= Cylindrical MCFL = Cylindrical, connections via flying leads MCUP = Cylindrical, unpackaged MCTP = Cylindrical, two-part construction IE = Independent elements IEHV = Independent elements, for use in a high vacuum chamber MS = square section NC = no connector |
B – Basic L – Low Standard – no letter |
±70 ±100 ±250 ±500 ±1000 |
Example: Mag-03MC100 is a standard noise sensor with a range of ±100μT.
* If no “L” is specified then the sensor is standard noise.
Note: For some Mag-03 magnetometers (Mag-03 MCFL, MCTP, MCUP, IE), lead lengths must be specified and this
length is included in the product identification. For example, Mag-03MCFL250-1000 is a Mag-03MCFL with a range
of 250μT and flying leads of 1000mm.
