WV5H25 | 4 - 20 mA HEATED

Enhanced wind vane sensor with analog output 4-20 mA Heated

WV5H25 | 4 - 20 mA RISCALDATO
Enhanced wind direction sensor with robust design, compact and modern. Manufactured of aluminum and high quality technical plastics. Dust and waterproof, corrosion and UV resistant.
The wind direction sensor WV5H25 has been designed for the use in industrial and domestic applications. Connected to devices such as data acquisition systems, PLCs, displays of analog signals it measures the wind direction, registers it and/or activates predefined alarm levels. Examples of use: irrigation control systems, automation in greenhouses, solar trackers, lifts at ski resorts, cranes, wind turbines, climate and weather stations and so on. To sum up, all applications that contribute to greater control and security in their facilities. The heated version generates 4-20mA output and works from -20 ºC. When the temperature is higher than +6º C, the heater switches itself offvautomatically to reduce the consumption
