Accelerometers and magnetometer
The MTi 10-series and MTi 100-series use the same accelerometers and magnetometer. The output
of the magnetometer is in arbitrary units (a.u.), one a.u. is the magnetic field strength during calibration
at Xsens
’ calibration lab. This is approximately 40 uT. An accelerometer range of 15g is available as
well.
Accelerometers/magnetometer: all products: MTi-10, MTi-20, MTi-30, MTi-100, MTi-200, MTi-300,

Barometer
The barometer features barometric (atmospheric) pressure. The MTi-100 series feature this
barometer. The MTi 100-series has three holes with a protective vent in its casing in order to ensure
fast adaptation inside the MTi to atmospheric pressure. Typical latency because of the vent is <10 ms.
