DWS-D-DAC13 – WIND VANE PNP/NPN HEATER

Why Choose the Carlo Gavazzi DWS-D-DAC13 Wind Vane Sensor?

The Carlo Gavazzi DWS-D-DAC13 is a robust wind direction sensor designed for detecting relative wind direction in demanding outdoor monitoring and control applications. Part of the Carlo Gavazzi DWS-D wind sensor series, it uses opto-electronic detection with binary PNP and NPN outputs to provide reliable directional information at 90° intervals.

Designed particularly for wind energy and environmental monitoring applications, the DWS-D-DAC13 incorporates a built-in heater to help reduce problems caused by icing in cold conditions. Its sensor body is manufactured from durable black PVC while the rotor is constructed from stainless steel, providing dependable mechanical performance in exposed installations.

The DWS-D-DAC13 operates from a 10–28 V DC power supply and is supplied with a 13 m shielded PVC cable for convenient field installation. With an operating temperature range of -20 to +60 °C, IP54 protection and protection against high humidity, salt and dust, it provides a practical solution for wind direction detection in industrial and renewable-energy systems.

Reliable Wind Direction Detection for Outdoor Control Systems

Wind vane sensors such as the Carlo Gavazzi DWS-D-DAC13 detect changes in relative wind direction and convert the vane position into electrical signals that can be processed by industrial controllers and monitoring equipment. The opto-electronic detection system provides directional information at 90° intervals through both PNP and NPN outputs, allowing straightforward integration with a wide range of control architectures.

For exposed installations, reliable operation depends on resistance to changing environmental conditions. The DWS-D-DAC13 combines IP54 protection, climatic protection against humidity, salt and dust, and an integrated heater that helps reduce icing risk. These characteristics make it particularly well suited to wind turbines and other outdoor systems where dependable wind direction information is required.

Typical Applications

• Wind turbine and wind energy systems.
• Relative wind direction monitoring.
• Renewable energy installations.
• Industrial weather monitoring systems.
• Outdoor automation and control equipment.
• Environmental monitoring installations.
• Building and infrastructure wind monitoring.
• Industrial systems requiring directional wind detection.
