WESTACH – 3DA5-149-1 – TACHOMETER (DUAL ENGINE / ROTOR RPM)

Aircraft dual-input tachometer designed to measure and display rotational speed (RPM) for two independent sources, typically an engine and a rotor system. Used in light aircraft, helicopters, gyroplanes, and experimental aviation to monitor both engine and rotor RPM simultaneously, providing pilots with critical performance and safety data during all phases of flight. Features an analog dial display with integrated dual-signal processing for separate RPM channels in a single 80 mm instrument housing.

Application: Aircraft engine monitoring, rotorcraft systems (helicopters/gyroplanes), dual RPM indication (engine + rotor), experimental and light aircraft instrument panels
Function: Measures and displays two independent RPM signals (engine and rotor), enabling real-time monitoring of propulsion and rotor system performance for safe operation and synchronization
