Wind Direction Sensor The Wind Direction Sensor is part of the SEVEN meteorological sensor range, which includes professional and intelligent measuring sensors with a digital or analog interface for environmental and industrial applications such as PV plants. The Wind Direction Sensor uses a Hall Effect Position Sensor operating based on magnetic field influence. This sensor detects changes in wind direction and converts them into a signal. The measured wind direction data is transmitted as analog or digital output signals to data loggers and receiving units, according to input requirements. SEVEN products use reliable, high-quality components to provide accurate meteorological information in environmental and industrial applications. The product is specially designed to meet the needs of PV plant monitoring systems and is offered with a choice of metal or plastic housing. High Accuracy Fast & Simple to Install Low Power Consumption Free Software Update SunSpec Compliant (for Modbus RTU) SEVEN Remote Setup Service SEVEN Customer Support 2 Year Warranty Models 3S-WD-A Small and economical wind direction sensors with 0–3,3 V analog output. They offer the best price/performance ratio for the standard requirements of industrial and environmental applications such as PV plants. With a seawater-resistant anodized aluminum body, they provide high durability against outdoor conditions. They can be connected to SEVEN Irradiance Sensor, Sensor Box, and Compact Weather Station models via a pin connector. 3S-WD-I-A Wind direction sensors with 4–20 mA analog output are specially designed for advanced industrial applications and environmental conditions. With a seawater-resistant anodized aluminum body, they provide high durability against outdoor conditions. This model is compatible with all dataloggers that have a 4-20 mA input. 3S-WD-MB-A Modbus wind direction sensors are professional and intelligent measuring sensors with a digital interface for environmental and industrial applications such as PV plants. With a seawater-resistant anodized aluminum body, they provide high durability against outdoor conditions. The measured value can be transmitted to monitoring instruments, data loggers, and other receiving units via the serial RS485 interface using the Modbus RTU protocol. 1 Pinarcay OSB Mah.
