JRC JLN-550 (Discontinued)
♦ 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.

JRC JLN-205MK2 (Discontinued)
The JLN-205MK2 is a stable and highly accurate measurement tool to ensure stable speed data utilizing high frequencies ultrasonic waves. The unit incorporates many display modes readily available on a highly visible 4.5-inch LCD display. Besides the display being fully dimmable and having backlit keys, it features dual LED backlight (white and orange), making it easy to operate in various light settings on the bridge

YDK EM LOG EML500
DOWNLOAD BROCHURE
• A preamplifier is built into the sensor for stable and long-distance transmission (max.300m long) of the current signal.
• The EML500 can receive a backup signal(NMEA-0183) from external speed sensors such as a GPS receiver.
• A dual-axis sensor (optional) measures a ship's transverse speed as well as its longitudinal speed.
