As well as magnetic field gradient data, the RS422 output also includes 3 axis accelerometer
data, as well as temperature information. Battery and multiplexing boxes are available to power
and convert the Grad-13 output.

Note:
Refer to the outline drawing DR3344 on the product webpage for further information.
The magnetometer assembly is supported on shock resistant mounts inside an electrically
isolated carbon fibre composite tube having ‘O’ ring seals at each end. Power is applied to the
unit and digital signals are output via an environmentally sealed connector.
The electronics are designed to minimise offset, scaling and orthogonality errors.
A temperature sensor and a test coil with a precision current source are included. Power supply
is provided using the Grad-13 Battery or Multiplexing Box, and basic software is provided to
interpret the RS422 digital data.
