제품 상세 설명

This is FT Technologies’ patented Acousti c Resonance technology. Acu-Res enables our sensors to take accurate measurements in a small space. This means our sensors are small, easy to heat, durable and strong. Acu-Res sets FT sensors apart from mechanical and other ultrasonic wind sensing technologies to give a more robust and reliable measurement soluti on.

The sensor works by creati ng a resonati ng ultrasonic signal inside the sensor’s measurement cavity. The moti on of air is sensed by measuring the phase change in the ultrasonic signal caused by the wind as it passes through the cavity. The sensor has three transducers arranged in an equilateral triangle. The net phase diff erence between a transmitti ng and receiving transducer pair is indicative of the airfl ow along the axis of the pair. Therefore by measuring all three pairs the component vectors of the airfl ow along the sides 
of the triangle are determined.

These vectors are combined to give the overall speed and directi on. The sensor uses complex signal processing and data analysis taking a sequence of multi ple measurements to calculate regular wind readings.

The sensor inherently compensates for changes in the air’s temperature, pressure or humidity. A strong resonati ng sound wave in a small space provides a large signal that is easy to measure. Acu-Res has a signal to noise rati o more than 40db stronger than other ultrasonic technologies.
    
 
EASY INSTALLATION

1 - Pass the cable through the pipe and att ach it to the sensor.
2 - Slide the sensor down over the pipe unti l it sits fi rmly on top.
3 - Rotate the sensor to align the datum (N).
4 - Tighten the grub screws one at a ti me to ensure there is an even distributi on of pressure.
