JLN-740 Doppler Log
JLN-740 Doppler Speed Log delivers high precision speed and distance measurement for ships, precisely responding to the IMO MSC.96(72) requirement for ships over 300 GT. Employing a pulse Doppler two-beam design and digital processor, it is able to make speed measurement with an accuracy of 0.03kn or 0.3% for constant speeds. Its bubble detect technology is unique, identifying whether air bubbles pose a problem interfering with accuracy so reducing maintenance checkdowns. An LCD display colour with touch panel is an option, offering greater visibility and control. The JLN-740 can be supplied in either three-unit or four-unit configurations, making it adaptable to a broad range of vessel sizes. The JLN-740 is also JRC Remote Maintenance System (RMS) compatible for diagnostics and support.
