The North Atlantic 801-40 Synchro/Resolver Panel Meter is a compact panel-mount instrument for precise measurement and display of synchro and resolver angle data. It combines a Type II tracking servo loop with 0.01° resolution and 0.03° accuracy to deliver real-time angular position measurements across industrial and aerospace systems. Direct rotor input operation and programmable signal conditioning eliminate auxiliary power requirements and reduce system complexity.
