Low pass electronic filter options Introduction Using the same torquer mechanism and servo electronics as the A220 series, the A260 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. The A260 series inclinometers have a long and successful market history under the Schaevitz® brand. Acquisition of this technology by Sherborne Sensors has allowed customers to benefit from the same exceptional product qualities as its predecessors, with the added benefits of extensive applications engineering support, global technical sales presence, repair, refurbishment and calibration services, stocking programs, and continuous product improvements.
