Nunotani Nautical Turn Rate Indicator

Manufacturer: Nunotani Nautical Instruments Mfg Co., Ltd

These rotating meters detect the rotation of the fly wheel for the ship engine, or of the slit panel equipped to the propeller shaft etc., using a proximity sensor. The detected pulse is converted into voltage signals in proportion to the rotation. These signals are indicated as the rotation direction and the frequency of the engine or the propeller shaft, on the receiver (indicator) located in a remote area (e.g. wheelhouse, engine control room).
