A thermal accelerometer comprising two detector strands having resistivity that is temperature sensitive, a detector member for detecting a temperature difference between the detector strands, a feedback member for establishing temperature equilibrium between the detector strands by supplying the detector strands with pulse feedback signals of variable width, a member for calculating acceleration, and a multiplexer member connected to the detector strands, to the detector member, and to the feedback member so as to perform the following in alternation: measuring the temperature difference between the detector strands; and providing the detector strands with the feedback signals, the widths of the pulse signals being determined by comparing a sawtooth signal with DC signals representative of the temperature difference between the detector strands.
