Navis WSS103/PULSE Wind Speed Sensor (0.6-50 m/s)

The Navis WSS103/PULSE wind speed sensor is an anemometer with a pulse output designed for wind power systems. The device features a measuring range from 0.6 to 50 m/s and a very low starting threshold of 0.5 m/s.

The Navis WSS103/PULSE anemometer utilizes a Hall effect sensor for accurate wind speed measurement. The output signal is a frequency type with a constant conversion factor of 4.0 Hz per 1 m/s. The device housing is made of anodized aluminum, and the replaceable cups are made of polyamide. The design allows for easy replacement of bearings and measuring cups directly on-site.

Key features

• Low starting threshold of 0.5 m/s
• Built-in reverse polarity and surge protection
• Replaceable precision stainless steel ball bearings
• Linear output curve and accuracy of +/- 0.15 m/s or 1.5%
