NUNOTANI KEIKI JIS F 8521-FE130K

This NUNOTANI KEIKI JIS F 8521-FE130K is a marine propeller shaft revolution indicator receiver complying with JIS F8521 marine standard for vessel propulsion monitoring. The marine shaft revolution indicator displays propeller shaft rotating speed and rotation direction on the ship bridge. The marine shaft revolution indicator receives proportional analog signal from shaft speed sensor transmitter. The marine shaft revolution indicator adopts round panel mounting design for installation on marine control console. The marine shaft revolution indicator meets marine environmental requirements to resist vibration and humidity onboard vessels.

This gauge delivers real-time visual RPM reading for ship propulsion operation supervision. The vessel propeller tachometer supports ahead and astern bidirectional rotation indication for main engine control. The vessel propeller tachometer uses marine grade dial with backlight for clear reading under variable lighting. The vessel propeller tachometer works with matched shaft pickup transmitter to form complete revolution measuring system. The vessel propeller tachometer is widely installed on cargo ships, tankers and offshore 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. 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.
