The NSGA transmitter is used to collect data from geophone sensors or seismometers, convert it into digital form, and transmit it to the surface station SP/DTSS or the underground station SD/DTSS.

The transmitter is a component of the DTSS digital seismic signal transmission system of the ARAMIS M/E system.

The NSGA transmitter is an intrinsically safe device of Group I, Category M1.

The signal inputs of the NSGA transmitter can be connected to the following vibration sensors:
- up to three geophone probes: GVu, GVd, or GHa,
- one triaxial probe: SG3/xxx or SG3/xxx-P,
- up to three seismic sensors: CS/DTSS.
