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.
A Hall Effect Position Sensor is used on the vane of the Wind
Direction Sensor. This sensor detects changes in wind direction and
converts them into a signal.
The measured wind direction data are transmitted as analog or digital
output signals to the data loggers and receiver units according to the
input requirements.
SEVEN products use reliable, high-quality components to provide
accurate meteorological information in environmental and industrial
applications.
They are specially designed according to the requirements of PV plant
monitoring systems.
Benefits and Features
• High Accuracy • SunSpec Compliant (for Modbus RTU)
• Fast & Simple to Install • SEVEN Remote Setup Service
• Low Power Consumption • SEVEN Customer Support
• Free Software Update • 2 Years Warranty
Models
3S-WD
Small and economical wind direction sensors with 0-3.3 V analog output. They are
ideal measurement transmitters with the best price/performance ratio for the standard
requirements of industrial and environmental applications such as PV plants. It can be
connected to SEVEN Irradiance Sensor, Sensor Box, and Compact Weather Station
models via a pin connector.
3S-WD-I
Wind direction sensors with 4-20 mA analog output are specially designed for advanced
industrial applications and environmental conditions. The housings are made of seawater-
resistant aluminum, making them extremely durable and resistant.
3S-WD-MB
Professional and intelligent measuring sensors with a digital interface for environmental
and industrial applications such as PV plants. The measured value can be transmitted
to monitoring instruments, data loggers, and other receiving units via the serial RS485
interface with the MODBUS RTU protocol.
