Wind direction sensor with 4-20 mA output PCE-WV A

Compact and robust sensor for wind direction measurement with analog output 4–20 mA, designed for direct integration into industrial systems (PLC, recorders, and SCADA). Its aluminum and high-strength plastic housing offers protection against corrosion, dust, water, and UV radiation, and the assembly is prepared for environments with RFI/EMI interference.

Key advantages:

• Standard 4–20 mA output for easy integration into industrial installations and control systems.
• Wide power supply range (12–30 Vdc) and low power consumption (maximum current 20 mA).
• Durable construction: corrosion-resistant materials, stainless-steel bearing, and IP65 protection rating.
• EMC certifications (EN 61000-6-2 and EN 55022 Class B) ensuring reliable behavior in demanding electrical environments.

Suggested applications:

• Weather stations and environmental monitoring systems.
• Integration into wind farms and power plants for control and logging.
• Precision agriculture projects and climate control in greenhouses.
• Port installations, civil engineering projects, and any application requiring reliable wind direction measurement.
