seismograph. A seismograph, or seismometer, is an instrument used to detect and record earthquakes. Generally, it consists of a mass attached to a fixed base.During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage.eismograph. A seismograph, or seismometer, is an instrument used to detect and record earthquakes.

Overview. Seismic sensors are devices used to measure seismic vibrations by converting ground motion into a measurable electronic signal. As the signal is analogue in nature, sensors must be linked to a data acquisition unit to convert its output into a digital format that can be read by computers.
