NUNOTANI KEIKI JIS F 8521-FL90K KG-3

This NUNOTANI KEIKI JIS F 8521-FL90K KG-3 is a marine propeller shaft revolution indicator receiver complying with JIS F 8521 marine standard for vessel propulsion monitoring. The marine shaft revolution indicator displays propeller shaft rotating speed and rotation direction including ahead and astern status on the ship bridge. The marine shaft revolution indicator receives analog signal from shaft speed transmitter to realize real-time RPM measurement. The marine shaft revolution indicator adopts round panel mounting design for installation on marine control console. The marine shaft revolution indicator is built to withstand engine room vibration, humidity and temperature variation for continuous onboard operation.

This gauge delivers clear visual RPM reading for ship main engine propulsion supervision. The vessel propeller tachometer uses marine grade dial with backlight for easy reading under variable lighting conditions on the bridge. The vessel propeller tachometer matches dedicated shaft pickup transmitter to form a complete revolution measuring system. The vessel propeller tachometer meets marine environmental requirements for commercial seagoing vessels. The vessel propeller tachometer is widely fitted on cargo ships, tankers and offshore supply vessels.

It serves as a vital spare instrument for marine propulsion monitoring system overhaul and repair. The NUNOTANI KEIKI marine tachometer is manufactured to original factory specifications for direct replacement. The NUNOTANI KEIKI marine tachometer reduces vessel downtime during propeller shaft monitoring system maintenance work. The NUNOTANI KEIKI marine tachometer supports simple wiring and fast on-site commissioning. The NUNOTANI KEIKI marine tachometer is stocked by marine automation spare parts suppliers worldwide.
