Nautical Navy Shaft Revolution Indicator System

Description: propellershaftrevolution indicator - the electric tachometer corporation Made by the Electric Tachometer Corporation in December 1942, the Navy Shaft Revolution Indicator System is a prized collector's item for its historical significance and advanced technology.During WWII, the US Navy relied on it to monitor and regulate ships' propeller shaft speeds. The system, with a tachometer generator, transmitter, and indicating unit, had the generator attached to the ship's propeller shaft.The generator produced an electrical signal corresponding to the shaft's rotational speed. The transmitter amplified the signal, displaying it in RPM on the indicating unit. Its precision was crucial in modern naval operations.Remarkably, some units still operate today, over 80 years later, a testament to their enduring durability and precision engineering. As a collector's item, it holds practical and historical value, making it a fascinating addition to collections focused on military or technological artifacts.Height:9Width:13Length:13Weight:50.5Visit Our Store on eBayIf you have any questions about this item or any other product listed you can contact us by clicking on the "Ask Seller a Question" link.Our customer service team can answer your questions, just contact us at (five seven four) - eight seven zero - one five seven one.Payment:eBay's Managed payments is the way most people pay us, but if you have other payment questions, just let us know.Shipping Information: Items are shipped within 2 business days.
