Detailed description

Designed for demanding marine environments, the FT743-D-SM KIT-1.5 ultrasonic wind sensor kit from FT Technologies provides accurate and reliable measurement of wind speed and direction. This digital sensor integrates FT Technologies’ patented Acu-Res® technology, which automatically compensates for variations in temperature, pressure, and humidity to deliver stable data. With a wind speed measurement range of 0 to 75 m/s and RS485 connectivity, this model is a robust solution for applications requiring high data integrity.

Design and technical performance

The FT743-D-SM stands out for its lack of moving parts, significantly reducing maintenance requirements and increasing long-term reliability. Its hard-anodized aluminum construction provides corrosion resistance to C5-M class and IP67 protection, ensuring operation even after temporary immersion or in intense dust conditions. The sensor operates within an extended temperature range of -40 °C to +85 °C and features integrated thermostatically controlled heating, configurable from 0 to 55 °C, to prevent icing. Weighing 252 g (sensor only) and 0.1 kg (cable), it is lightweight and compact. It is powered by 6 to 30 VDC (minimum 2A).

Integration and positioning within the FT Technologies range

The FT743-D-SM KIT-1.5 kit includes the FT743-D-SM wind sensor and a 1.5m FT009 cable, specifically designed for use with FT742-SM and FT743-SM sensors. This cable is rated for 30VDC / 2A and has a minimum bending radius of 70 mm. Compared to the FT6 series, which is lighter at 170 g, the FT743-D-SM from the FT7 series offers a potentially higher wind speed range (up to 90 m/s for the FT7 series in general) and robustness suitable for the most demanding applications. The FT743-D-SM differs from models like the FT702LT, which provides 4-20 mA analog outputs in addition to RS485, by focusing on digital RS485 connectivity for simplified integration into modern systems. Each sensor is factory-calibrated and requires no scheduled recalibration, ensuring data availability exceeding 99.9%.

« FT743-D-SM: ultrasonic precision for demanding marine environments »

The FT743-D-SM ultrasonic wind sensor from FT Technologies is a top choice for professional marine applications where wind data reliability and accuracy are critical. Its utility is particularly high for racing sailboats, large cruising yachts, and coastal or offshore weather stations, where environmental conditions are often extreme. The integration of Acu-Res® technology is a major asset, allowing the sensor to maintain constant accuracy even in the face of rapid temperature and atmospheric pressure variations—critical factors at sea.

In terms of installation, the FT743-D-SM is designed for relatively straightforward implementation. Its flat front mounting facilitates alignment, and the kit includes the 1.5m FT009 cable, optimized for this series. It is essential to follow the installation instructions, including applying the non-silicone lubricant to the supplied O-ring and correctly tightening the mounting screws (not included) to ensure IP67 waterproofing. For lightning-prone and salt-exposed areas, consulting the product manual is critical for additional protective measures. This sensor stands out from cup or propeller anemometers by having no moving parts, thus eliminating mechanical failures due to wear, freezing, or debris.

This model is particularly well-suited for digital systems thanks to its RS485 interface, facilitating integration with multifunction displays (MFD) or performance computers compatible with NMEA 0183/2000 via an appropriate bridge. It excels in scenarios where continuous data availability is non-negotiable, such as on commercial vessels or autonomous weather buoys. It should be noted that for installations on very tall masts or complex structures, longer cables will need to be ordered separately, as this kit includes a 1.5m cable.
