  • Page 7: Introduction

    Section 1 Introduction 1 INTRODUCTION 1.1 Product Overview The FT742-SM is a solid-state ultrasonic wind sensor, using a patented Acoustic Resonance airflow sensing technique to measure accurately both wind speed and direction. The sensors have been specifically designed to operate in harsh environments including offshore and ice-prone areas. The wind sensor has no moving parts to degrade or wear and is designed for applications requiring high reliability.

  • Page 10: Wind Speed Calibration

    The sensor’s compact strong monolithic shape is designed to prevent accidental transducer movement or damage. FT Technologies’ calibration procedure and wind tunnels are designed to give a calibration profile that is within the accuracy limits set in the product technical specification (see Section 2.1).

  • Page 11: Electronically Offsetting The Wind Direction Datum

    Section 2 Functional Description 2.4 Electronically Offsetting the Wind Direction Datum For applications where the compass is not being used, the wind direction datum can be ‘electronically’ rotated using the CF command. The declination angle function normally used in conjunction with the compass function can be used to realign the datum position anywhere in the range 0-359.9°.

    CU data output and WV Query commands. See Sections 7.4.7, 7.4.8 and 7.4.29 for further information. Caution: The acoustic temperature feature requires calibration at FT Technologies. If the sensor has had a software upgrade to 7.5 (or above) then the data will be uncalibrated and may not comply with the official specification.

  • Page 14: Mechanical & Electrical Installation

    Section 3 Mechanical & Electrical Installation 3 MECHANICAL & ELECTRICAL INSTALLATION The FT742-SM has a surface-mounted design for installation on flat surfaces. The product range is optimised for cost-efficient operation including the use of standard off-the-shelf cables. The sensor uses an 8-way M12 connector. IP66 and IP67 ratings are achieved through the use of a compression fit O-ring seal.

Polar, NMEA 0183 and Combined (Polar Wind & Temperature) data formats are available. Use the DF command (Section 7.4.8) to select the output format. Polar Format: The sensor returns the magnitude of the wind speed (m/s) and the wind direction (0-359°).
