PRE OWNED NINGLU NINGLU IR761 NINGLU IR761 ANEMOMETER

PRODUCT DATA SHEET: NINGLU IR761 WIND REPEATER

PRODUCT OVERVIEW

The Ninglu IR761 is a dual-function digital wind repeater that provides instantaneous monitoring of both wind speed and direction. Encased in a standard 144x144 DIN cabinet, it is designed for seamless flush mounting into bridge consoles. The unit receives standard NMEA 0183 signals from a marine anemometer (talker) and presents the data using a combination of high-brightness digital LEDs and a double LED circle for directional tracking. It is a rugged, maintenance-free solution for any vessel requiring a dedicated, easy-to-read wind station.

KEY FEATURES & APPLICATIONS

Combined Visuals: Displays wind speed and maximum wind speed (MAX) on digital LEDs while simultaneously showing 360° wind direction on a high-contrast double LED ring.

Selectable Units: The operator can easily switch wind speed units between knots, m/s, km/h, and mph using the front-panel 'S' key.

True/Relative Modes: Supports toggling between "True" and "Relative" wind modes (provided the input signal contains both) using a dedicated function key.

Integrated Dimmer: Includes front-panel touch controls (▲▼ keys) for LED brightness, ensuring the display does not interfere with night vision on the bridge.

Max Wind Interval: Users can select the measurement interval for max wind speed (1, 2, 5, or 10 minutes) for accurate weather logging.

Error Detection: Features built-in signal monitoring; the screen will display "ERR" if the NMEA signal is lost and "- - - -" if the incoming data is corrupted or incorrect.

Versatile Mounting: While designed primarily for flush-panel mounting, the unit can also be installed on a tabletop, wall, or ceiling using a specialized U-bracket.

TYPICAL CONDITION (USED/REFURBISHED)

Sourcing: These units are often collected from demolished ships. They are highly durable due to the lack of moving parts.

Quality Check: Refurbished units should be tested for "dead segments" in the LED circle and for the responsiveness of the tactile front buttons.

Compatibility: Because it uses the universal NMEA 0183 MWV sentence, it can be used as a repeater for almost any brand of anemometer (Furuno, JRC, DEIF, etc.).
