Two mandatory core configurations: full anti-corrosion housing made of 316 stainless steel + full-range intelligent heating & de-icing system.
1. Core Pain Points Unique to This Environment
- Dual Corrosion Hazards: Year-round sea salt splash and chloride ion penetration. Ordinary aluminum alloy or plastic components suffer rust failure within six months.
- Probe Malfunction Caused by Ice Buildup: Temperatures ranging from -20℃ to -50℃, freezing rain, heavy snow, and sea fog frost form ice layers that block ultrasonic signals and jam mechanical wind cups.
- Extreme Strong Winds: Roaring Westerlies and North Atlantic storms generate gusts reaching 70~100 m/s.
- Temperature Drift Errors: Diurnal temperature fluctuations exceeding 30℃ lead to severe measurement inaccuracy without wide-temperature circuit compensation.
- High Humidity Condensation: Marine air at 100% relative humidity causes short circuits and mildew on internal circuit boards.
- Vibration from Vessels & Offshore Platforms: Hull sway and wind turbine tower vibration require attitude compensation for reliable data output.
2. Wind Speed Range (Core Requirement)
- General land & port applications: 0~60 m/s
- Southern Patagonia, offshore vessels & wind power generation: 0~75~90 m/s, with reserved margin for extreme storm conditions
- Starting wind speed: ≤0.1 m/s, enabling accurate measurement of faint breezes in deserts and fjords
3. Measurement Accuracy
- Wind speed error: ≤±0.5 m/s or ±5% (whichever is stricter)
- Wind direction accuracy: ≤±3°, full 0~360° coverage without blind zones
- Output Interfaces: RS485 (Modbus), 4-20mA, NMEA0183 (mandatory for marine vessels), compatible with local industrial control and meteorological acquisition systems
HT/SW50H Ultrasonic Wind Sensor
4.1 Product Overview
The HT/SW50H ultrasonic wind sensor calculates wind speed and wind direction based on the time difference and phase difference of ultrasonic wave propagation in air.
The entire unit adopts an integrated 316 stainless steel housing with a built-in full-range automatic heating and de-icing temperature control system, reaching an IP67 protection rating. Without rotating mechanical parts, it delivers maintenance-free operation.
Custom-designed for offshore wind turbines, polar ports, high-altitude frigid and sandstorm zones, the sensor maintains stable long-term operation under complex environments such as marine salt spray, freezing rain ice coating, extreme gusts and high-humidity condensation.
4.2 Core Adaptation Advantages (Matching Environmental Pain Points)
Full 316 Stainless Steel Anti-Corrosion Body to Resist Marine Salt Spray Erosion
The outer shell is made of molybdenum-bearing 316 stainless steel with strong resistance to chloride salt spray corrosion. Compared with sensors made of ordinary aluminum alloy or plastic, it can serve long-term in coastal and offshore platforms with heavy salt spray, eliminating rust failure within six months.
Built-in Full-unit Automatic Heating & Temperature Control System to Eliminate Ice Malfunctions at Low Temperatures
Equipped with an integrated full-range heating module suitable for temperatures as low as -40℃. It automatically melts ice formed by freezing rain, heavy snow and sea fog frost, preventing ice layers from blocking ultrasonic probes or jamming mechanical wind cup structures, and ensuring continuous data collection throughout frigid winters.
No Rotating Mechanical Parts, High Wind & Sand Resistance, Maintenance-Free
Eliminates movable components like traditional wind cups and wind vanes. The integrated ultrasonic probe features a robust impact-resistant structure. An optional extended measuring range of 0~75m/s is available, which handles extreme storm gusts of 70~100m/s in Patagonia and the North Atlantic. It withstands abrasion from strong winds and sandstorms with zero on-site maintenance over long service periods.
Multi-dimensional Environmental Compensation Algorithms to Eliminate Measurement Deviations in Harsh Conditions
Integrated acoustic phase compensation and wide-temperature digital filtering algorithms automatically offset measurement drift caused by heavy rainfall, large diurnal temperature swings, thunderstorms, sandstorms and altitude changes. It suppresses circuit board short-circuits under 100% high marine humidity, and digital filtering technology enhances anti-electromagnetic interference capability to deliver stable data output under vibration from vessels and wind turbine towers.
Multi-brand Protocol Compatibility for Seamless Connection to Existing Meteorological & Industrial Control Systems
Natively compatible with mainstream imported meteorological device communication protocols including THIES, FT, Lambrecht, Kriwan, NRG and LUFFT. It outputs standard full-duplex RS485 signals, enabling seamless integration with local data acquisition and industrial control platforms deployed at ports and offshore wind farms without full replacement of existing collection equipment.
