TACH GENERATOR

The tach generator, part number 50-389057-1, is an essential component used in aircraft to measure the rotational speed of the engine. It provides critical data to the pilot and aircraft systems, ensuring optimal engine performance and safety. This tach generator converts mechanical rotational energy into electrical signals, which are then used to display engine RPM on the cockpit instruments. Accurate engine RPM readings are crucial for maintaining engine health and preventing over-speed conditions, ensuring the longevity and reliability of the engine.

The tach generator is typically mounted on the engine and mechanically connected to a rotating component, such as the crankshaft or accessory gearbox. The device uses electromagnetic induction to generate a voltage proportional to the rotational speed. This voltage is then transmitted to the cockpit instruments, providing real-time RPM data.

Regular maintenance and calibration of the tach generator are necessary to ensure its accuracy and performance. Common maintenance tasks include checking the mechanical connections, inspecting the electrical output, and recalibrating the device to ensure it meets the manufacturer’s specifications. Precision Aviation Group specializes in providing high-quality tach generators like the 50-389057-1, along with comprehensive maintenance services to ensure their reliability. Our technicians are trained to handle all aspects of tach generator maintenance, from inspections to repairs and replacements.
