Title: Accelerometer incorporating fluid suspended magnet
Inventor: EVANS KENNETH STEPHEN
IPC: G01P15/11
Filed: 1990-03-06
Abstract: An accelerometer 1 comprises a housing 2 defining a cylindrical chamber 3, a magnetisable fluid (ferrofluid) 9 within the chamber 3, and a permanent magnet 4 magnetically suspended within the chamber 3 by the ferrofluid 9. The magnet 4 is movable from a null position within the chamber by an applied acceleration, such movement being detected by sensing coils 28 and 30 and associated circuitry which supplies an electrical signal indicative of the applied acceleration and also energises restoring coils 24 and 26 which restore the magnet 4 to its null position. Ultrasonic transducers 10 and 11 are provided for transmitting vibratory waves within the ferrofluid 9 in order to dislodge magnetisable particles which have migrated within the ferrofluid 9 towards the poles of the permanent magnet 4. Prior to calibration of the accelerometer and also prior to a measurement being taken, the transducers 10 and 11 may be energised so as to decrease the concentration of magnetisable particles in the vicinity of the poles of the permanent magnet 4, ensuring that similar conditions apply in relation to the concentration of particles within the ferrofluid 9 both during calibration and measurement so that the measurement accuracy of the accelerometer is increased. <IMAGE>
