- Potential Applications of an Integrated Seismic, Tilt & Temperature Instrument | Presentation/Poster
Mass position represents a quasi-static acceleration applied to the inertial mass of a seismometer to keep it balanced at its operating point. This acceleration changes with tilt (due to gravity) and temperature (due to the temperature coefficient of the springs). Mass position is typically recorded with low resolution as a state of health measurement for a seismometer. However an optimized output circuit for high-resolution mass positions fed to a 24-bit digitizer would enable the derivation of simultaneous seismic, tilt, and temperature datasets from a single instrument, for applications such as volcano and reservoir monitoring.
