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.
