AIR VELOCITY SENSORS

Applications & Features

It is designed for air velocity monitoring and controlling in the ventilation
system and reducing energy consumption in BMS and various HVAC
application. It is applied for single point air velocity measurement. SAVTD is for duct mount, SAVTR is for remote installation

Based on thermal anemometer principle, use innovative and sensitive hot film sensor, which is insensitive to dust and dirt, easy to install and maintain

No moving parts, provide accurate, reliable, sensitive and long term measurement, with good temp. compensation

Multiple outputs, ranges and optional LCD display
