An accelerometer includes a thermocouple circuit which comprises a movable member and a second member which abuts the movable member, wherein the abutting parts of the members include a cutting portion and wherein said parts are composed of dissimilar metals, for example steel and tungsten carbide, and recording means connected to the members for recording a thermoelectric signal generated when the cutting portion cuts the abutting part of the other member during acceleration.
