Wind Pressure Measuring System

Summary

The measurement system capable of simultaneously measuring gentle breeze pressure changes of wind tunnel and performing data processing through multiple dedicated micro-pressure sensors. For example, the system can make wind tunnel experiments for building models, and predict and improve the wind pressure suffered by buildings and the wind effect on
surrounding buildings. In addition it is used to measure indoor air pressure distribution. It is used for research of improvement in the amenity by the ventilation method.

Features

●Capable of corresponding to low-speed wind tunnel
●Realizing measurement with excellent SN ratio and high resolution through the micro-pressure
sensor signal amplified by each sensor’s amplifier
●High frequency responsiveness of system, capable of responding to both static and dynamic frequencies
●Improving measurement reliability and accuracy through the automatic calibration of micropressure sensor
●Able to customize the system, as each unit has scalability.
