Wind speed
compact size and high mechanical strength, these sensors are particularly suited for use in strong wind applications.
Sensors with no moving parts
Ultrasonic Anemometers are the ideal sensors for general meteorological applications requiring no moving parts for low-maintenance or measurements with fast response even in very low-range wind speed conditions. Model DNB205 (serial output) is a compact size sensor very suitable in lite weather stations. DNB305-305.1 (serial output) are made in Aluminum and have very good performances. DNB306-306.1 models have 4÷20 mA outputs. DNB105.1 model is made for high speed range up to 85 m/s, it comes with 4÷20 mA output.
• Wide range of signal outputs 4-20 mA, RS232/485 Modbus;
• No moving parts;
• Very-High speed wind measurement (0-85 m/s) using DNB105.1 modek;
• Fast response time and low measurement threshold;
• Low cost compact versions option (DNB205/205.2);
• In-house ISO17025 calibration laboratory.
