{"product_id":"ft-technologies-ft742-a-dm","title":"FT Technologies FT742-A-DM - Analog Ultrasonic Anemometer","description":"\u003cp\u003e\n    The \u003cstrong\u003eFT Technologies FT742-A-DM ultrasonic anemometer\u003c\/strong\u003e is designed for measuring wind speed and direction in a wide range of meteorological applications, including harsh environments such as icing, sand, dust, and offshore installations. This sensor uses acoustic resonance airflow detection technology for reliable measurement without moving parts, ensuring high data availability (greater than 99,9 %). Its hard-anodized aluminum alloy body offers resistance to corrosion, shocks, vibrations, solar radiation, and bird attacks.\n\u003c\/p\u003e\n\n\u003ch3\u003eDesign and Technology\u003c\/h3\u003e\n\u003cp\u003e\n    The FT742-A-DM incorporates a thermostat-controlled three-element heating system, ensuring uniform heat distribution across its entire surface for efficient operation in icing-prone areas. The acoustic resonance measurement principle automatically compensates for variations in temperature, pressure, and humidity, ensuring accurate readings. The direct mounting design fits a tube with 33,7 mm outer diameter (EN10255 standard), secured by four M6 screws.\n\u003c\/p\u003e\n\n\u003ch3\u003eMeasurement Performance\u003c\/h3\u003e\n\u003cp\u003e\n    This sensor provides precise wind speed and direction data. For speed, the range is 0 to 75 m\/s with a resolution of 0,1 m\/s and an accuracy of ±0,3 m\/s (from 0 to 16 m\/s), ±2 % (from 16 to 40 m\/s) and ±4 % (from 40 to 75 m\/s). Direction is measured over a range of 0 to 360° with a resolution of 1° and an accuracy of 4° RMS. Outputs are managed by two 4-20 mA analog current loops, one for speed and one for direction, updated 10 times per second and galvanically isolated. A semi-duplex RS485 configuration port is available for internal settings and temporary diagnostics.\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegration and Environment\u003c\/h3\u003e\n\u003cp\u003e\n    Required power supply ranges from 12 to 30 V DC (nominal 24 V DC), with a typical consumption of 31 mA (heater off) and a maximum of 6 A (heater on, limited to 4 A by default). The sensor is certified IP66, IP67, and IPX6K, ensuring protection against dust and powerful water jets, including high-pressure jets. Its operating and storage temperature range extends from -40°C to +85°C, and it operates in humidity conditions of 0 to 100 % and at altitudes up to 4000 m. The FT742-A-DM has passed over 30 environmental tests, including corrosion, icing, shock, and electromagnetic interference.\n\u003c\/p\u003e\n\n\u003ch3\u003eDetailed Technical
