Cup anemometer 3S-WS-MB-P

for solar power plantsModbusRS-485

Overview
The 3S-WS-MB-P is a compact cup anemometer designed for reliable wind speed measurement in solar PV plants and other outdoor monitoring installations. It provides digital Modbus RTU output over RS485 for straightforward integration with dataloggers and SCADA systems. Supplied with a 3 m LIYYC11Y PUR cable for UV and weather resistance, the sensor is built for long-term field use.
