High accuracy closed loop operation. Infinite resolution. Excellent repeatability. High environmental resistance. Fast response. Low power unregulated supply. High level, low impedance output. Low price. Operation Principle: A pendulum is suspended from a low stiffness torsion spring. Pendulum rotation can be induced by a linear acceleration along its sensitive axis (acceleration mode), or by a component of the gravity force along that axis caused by tilt (tilt mode). Pendulum axis Light emitter Light detector Torsions spring Pivot axis Sense resistor The polarity of the connection is chosen to produce a reaction torque which tends to return the pendulum to its zero position (negative feedback). Since the input and reaction torques exactly balance each other, the current producing the reaction torque is a very accurate and linear function of the acceleration and is used as output. In the tilt measuring mode, the output is proportional to the sine of the angle of tilt. This fact limits the affectivity of the sensor for tilt angles approaching ±90 degrees. The pendulum displacement is sensed by a photoelectric position sensor, the output of which is amplified and fed to the coil of an electromagnetic torque attached to the pendulum.
