  • Lufft VENTUS Ultrasonic Wind Sensor Proven for Offshore Operation
    The Lufft Ultrasonic Anemometer VENTUS-UMB successfully completed the test at the International Technical Inspection Agency TUEV SUED and now has the Protection Class IP68. This confirms officially that the sensor is one of a few Ultrasonic Anemometers, protected from infiltration of dust as well
  • Measuring Air Flow
    Building Automation Systems are often required to measure the actual air flow in air handling systems. Although there are many ways to measure air flow, the two most commonly used with BAS systems are the hot wire anemometer and various devices which measure the velocity pressure of the air. Once
  • LDE/LME Series - superior immunity to dust
    In this application note LDE/LME differential pressure sensors from First Sensor are experimentally compared to other sensors which use the same (thermal-anemometer-based, non-membrane) sensing principle, where differential pressure is inferred from a gas flow through the sensor. With dust
  • LDE/LME Series - superior immunity to humidity
    In this application note LDE/LME differential pressure sensors from First Sensor are experimentally compared to other sensors which use the same (thermal-anemometer-based, non-membrane) sensing principle, where differential pressure is inferred from a gas flow through the sensor. In high-humidity
  • Shedding New Light On Tiny Packages
    Welds 0.1 mm wide? No problem. Recent laser transmission welders join plastic components with unprecedented precision. These micrographs show seams made with the mask welding procedure. The gray shaded area is welded. A MEMS silicon mass flow sensor contains a highly sensitive thermal anemometer
  • 100 years of flight - Keep them flying : Navigation
    A pilot's priorities are to aviate, navigate, and communicate, in that order. Here's a look at some of the devices developed over the last 100 years that help pilots do all three. When the Wright Brothers first flew, their plane carried an anemometer to measure wind speed, a revolution counter
  • "Tunnel Vision " Tracks Emissions Dispersal
    With most of his upper body inside the wind tunnel, soil scientist Tom Sauer exchanges one of the highly sensitive sensor tips in the hot film anemometer before one of many experiments measuring airflow and turbulence. In the basement of the National Soil Tilth Laboratory (NSTL) in Ames, Iowa
  • Justifying a continuous contamination monitoring system
    anemometer measurements would be taken near the face of HEPA filters to confirm linear discharge velocities, verifying that the room air recirculation system is functioning correctly. This would involve taking a large number of measurements and so would be done infrequently. Often such a survey would only
