ACCELEROMETER

PROBLEM TO BE SOLVED: To obtain an accelerometer for detecting the acceleration accurately at all times in which the scale factor is insusceptible to temperature variation. SOLUTION: A temperature resistive element 120 is mounted on a base 10 constituting a torquer and the temperature variation thereof is detected as resistance variation of temperature resistive element 120. An operational amplifier circuit comprising the temperature resistive element 120 and an additional resistor receives the currents being fed to torquer coils 34A, 34B and outputs a voltage signal indicative of detected acceleration. Resistance of the additional resistor is set as follows; b=[(R10 +R2 )/R2 ]a, where (b) is the temperature coefficient of temperature resistive element 120, R10 is resistance of temperature resistive element 120 under normal temperature, R2 is resistance of the additional resistor, and (a) is the temperature coefficient of torquer constant of torquer.
