Size: Typically 100-200 mm in diameter for display units, sensors vary by model.
Grade: Marine-grade, compliant with ISO 8729 and IEC 60945 standards.
Viscosity: Not applicable to wind speed indicators; applies to lubricants in moving parts (e.g., ISO VG 32 for bearings).
Buoyancy: N/A for indicators; sensors may have buoyant mounts if floating-type.
Material: Housing—stainless steel (316L) or UV-resistant ABS plastic; sensors—anodized aluminum or reinforced polymers.
Wind Speed Range: 0-60 knots (standard), up to 100 knots (heavy-duty models).
Accuracy: ±1% of full scale or ±0.5 knots (whichever is greater).
Output: Analog (4-20 mA) or digital (NMEA 0183/2000, RS-485).
Operating Temperature: -20°C to +60°C (standard), -40°C to +70°C (extended).
Protection Rating: IP66 or IP67 for water and dust resistance.
Mounting: Mast-mounted (sensor), panel or bracket-mounted (display).
Power Supply: 12/24V DC (marine electrical systems).
