OMC-116 Ultrasonic

Marine meteorological observations require devices designed to withstand the hardest environmental conditions, such as heavy vibrations, sea spray, extreme colds, chemical particles etc. With a major track record the marine and offshore markets are the home markets for Observator’s meteorological product line. The OMC-116 is an ultrasonic wind sensor, based on the time of flight theory. The unit is provided with industrial standard NMEA0183 output and can optionally be provided with 4.20 mA signals. The robust design of stainless steel of marine grade aluminium, as well the standard available heating, makes this unit ideal for the hardest environments. The standard bracket with integrated junction box makes this unit easy to install.

JLN-650

The new JLN-650 Doppler current meter continues the tradition of enhanced acquisition of speed and tidal current data, but now with a newly designed transducer and the integration of an extensive range of function and features. You can view the current direction and speed in up to 100 layers with the twist mode. With this advanced feature, an operator is able to anticipate current speed and direction, enhancing the timing on when to deploy the nets in the water. Naturally, the twist display mode is accompanied with a wide range of information, such as current speed range, depth range, temperature and so on. You can view fish echoes in four-directions, two-directions ahead, or in any one direction, allowing for easy fish tracking. Just as any typical fish finder, you can set the display to the type of fish or sea conditions simply by adjusting the sensitivity.

JLN-652

The new JLN-652BB Doppler current meter integrates a compelling combination of function and features, packed into a compact space-saving design, enabling quick and accurate acquisition of speed and tidal current data. JRC engineers listened closely to feedback given by captains and realized yet another unique function in this class of current meters. The JLN-652BB is able to accurately measure up and down current, particularly useful to predict the sinking ratio of your nets by following the natural motion of the underwater current. The JLN-652BB Doppler current meter has the ability to process and display continuous tidal currents of 50 independent measuring layers down to maximum 200 meter depending on sea condition. To simplify matters, the user only has to set five depths layers (A, B, C, D, E), of which each layer is measured in four directions. The 50 layers are automatically set relative to depth which has been indicated.

JFE-380

The JFE-380 echo sounder continues the tradition of enhanced depth data technology resulting in highly accurate and reliable read-out functionality. JRC’s enhanced depth data technology has three central presentation modes, i.e. standard, history and docking. Both standard and docking mode provides a wide range of information. This is stored in the memory for up to 24 hours. The history mode allows you to retrieve all memorized depth data to provide complete feedback. JRC’s new echo sounder incorporates a 6.5-inch high visibility color TFT display. The innovative display modes allow you to select and view echoes in 8 colors or 8 levels of monochrome. Additionally, the size-reduced JFE-380 echo sounder incorporates printer adaptability, providing the ship’s log with valuable printouts if required. The compact connection box can be installed out of sight. An optional dual frequency configuration, 50 kHz and 200 kHz, allows you to operate both frequencies independently or simultaneously, or allows you to have a separate bow-stern depth read-out.

JRC’s enhanced depth data technology has three central presentation modes, i.e. standard, history and docking. Both standard and docking mode provides a wide range of information. This is stored in the memory for up to 24 hours. The history mode allows you to retrieve all memorized depth data to provide complete feedback. JRC’s new echo sounder incorporates a 10.4-inch high visibility color (640x480 pixels) LCD TFT display. The innovative display modes allow you to select and view echoes in 8 colors or 8 levels of monochrome. Additionally, the good size of the JFE-680 echo sounder incorporates printer adaptability, providing the ship’s log with valuable printouts if required. The outline of this equipment provides a wonderful view of the depth details where your vessel stands. With depth ranges of 10, 20, 50, 100, 200, 500, 800m and with e depth accuracy of ±2.5% provides you a reliable data for any further decisions. The compact connection box can be installed out of sight.

JLN-205Mk2

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. Multiple display modes are available from the menu with main data displayed in large characters for easy reading. You can easily switch at your own convenience, particularly useful when a situation requires specific information. The transducer is compact and constructed of light weight moulded rubber, to minimize the effects on aeration, which allows stable and accurate operation. Using an optional gate valve transducer allows for long-term cost saving and easy maintenance as dry docking is not necessary. An ultrasonic beam is transmitted in fore and aft directions. At the same time, the hull motions such as rolling and pitching are detected and removed by simply measuring the difference of the Doppler shift reception signal, ensuring accurate and stable speed data, even in the roughest conditions.

JLN-720

The JLN-720 satellite log provides accurate ship speed and distance right with your fingertip operation. Regardless of weather conditions, the system is capable of providing accurate speed up to an amazing 0.02kn or 0.2% all over the world using JRC’s proven GPS compass technology. On the bridge the system is operated on a color LCD display with touch panel, providing clear and straightforward information. The processor is built into the antenna which eliminates alignment between antenna and processor, therefore contributing to an easy setup with less error and significantly reduced installation time. This concept also reduces the installation costs as only a single cable is used between antenna and processor unit. Should something interfere with the coverage, the proven antenna design incorporates a layer of air that reduces possible blind spots, allowing for a more precise speed than conventional systems.

JLN-740

The JLN-741A series is a single axis water SDME compliant with the IMO MSC.96 (72) standard, required on all internationally voyaging ships exceeding 300 GT. Boasting never-before-seen accuracy for speed measurement, the JLN-740 is also installed with our company’s proprietary bubble detection function, which informs you when measurement accuracy is impaired due to air bubble contact. The JLN-741A series utilizes digital signal processing, which, coupled with optimizations to existing speed measurement waveforms and the reliability of ship bottom mounting, has resulted in water speed measurement with accuracy up to 0.03kn or 0.3% in all models (measured at fixed speeds). That accuracy of information allows for highly fuel-efficient speeds, which means faster voyages with less waste. Along with improved speed measurements, the series also has greatly improved ship speed tracking, relaying all the information you need for precise navigation during berthing. A long-unsolvable problem with doppler-based water speed measuring systems was reduced accuracy from bubbles making contact with the measuring device on the bottom of the vessel. The JLN-741N series detects when bubbles contact the transducer, and using roprietary technology from JRC alerts you of reduced measuring accuracy via the display. Confirming the source of the issue typically requires visually examining the device on the bottom of the ship. However, onboard air bubble detection allows you to skip unnecessary preventive maintenance.
