Abstract
The thermal accelerometer of the invention comprises an enclosure having disposed therein a central filament powered by alternating electric current of zero mean amplitude and having a frequency lying between first and second resonant modes of vibration of the central filament, the central filament lying between detector filaments adjacent to reaction filaments powered by alternating electric current of zero mean amplitude and having a frequency lying between the first and second resonant modes of vibration of the reaction filaments.
