AAA260 Servo Accelerometer
High resolution gravity referenced linear servo acceleration sensor with pivot-on-stone
About the AAA260 Servo Accelerometer
Using the same torquer mechanism and servo electronics as the AAA220 series, the AAA260 features a switching regulator to enable direct operation from a single ended dc power supply. Galvanic isolation between primary and secondary circuits provides total electrical isolation between the input supply and signal output. To meet certain measuring requirements, especially in certain aerospace applications, this series has provision for an optional active filter with low output impedance and 1g bias circuitry for vertical mounting.
