Stable Speed Display in Dual Frequency Modes
The JLN-550 Doppler Sonar is designed to provide ship speed information with higher stability in the dual frequency modes; one using a lower ultrasonic frequency that is adequate to measure the ship’ s speed against the ground up to larger depths and the other using a higher ultrasonic frequency that allows the ship’ s speed against the water to be measured even in water with tiny bubbles. The transducer is designed for dual-frequency transmission, but its size is smaller than the conventional models. This equipment is designed to comply with the following standards:
（１９） ＩＭＯ Ａ． ８２４ Revised MSC.９６(７２), IMO A.６９４ （１ ７）, IEC６1０２３ ： １９９９, IEC６０９４５ ： ２００２ and IEC６１１６２-１ ： ２０００
FEATURES Ship speed measurement is insensible to bubbles generated in high-speed navigation, ensuring stable speed display. The transducer is substantially downsized, allowing it to be installed on the bow side that is little affected by bubbles. An underwater-mateable connector is adopted for the transducer, so that a transducer can be replaced at a quay even in case of its failure. The equipment is provided with an additional function of indicating the ship’ s fore and aft speeds and port and starboard speeds by entering GPS information. The ship’ s port and starboard speeds at its arbitrary position can be indicated by entering ROT information. An optimal Doppler sonar system can be configured by combining a variety of options. On-line maintenance (option) allows any failure to be detected during navigation.
