<p>The accelerometer comprises a main permanent magnet and a guide which houses the main magnet and enables it to travel in a given prearranged direction. Two magnetic field generators are provided where the respective north and south poles are arranged facing identical north and south poles on the main magnet. The generators exert respective repelling forces on the main magnet which, when idle, maintains the main magnet dynamically balanced inside the guide. A coil is located between the field generators which are coaxial in relation to the main magnet and in the travelling direction. A constant supply current is delivered to the coil including a common base connected transistor having a resistor-capacitor network connected in series across its emitter-base terminal and the coil connected in parallel with the resistor of the resistor-capacitor network. A signal comparator compares the output signal generated by the coil.</p> |
