Wind Pressure Measuring System

Summary

The measuring system simultaneously measures wind pressure changes of wind tunnel and performs data processing by multiple dedicated micro-pressure sensors.
For example, the system carries wind tunnel experiments on building models, predicts and improves the wind pressure suffered by buildings and the wind effect on surrounding buildings.
In addition, the system is used for measuring indoor air pressure distribution and for improving the living comfort by the ventilation method.

Features

●Rated capacity of 2.5 kPa supports low-speed wind tunnels.
●Realizing measurement with excellent SN ratio and high resolution through the micro-pressure sensor signal amplified by each sensorʼs amplifier
●Supports both static and dynamic frequencies.
●The automatic calibration of micro-pressure sensor improves the measurement reliability and accuracy results.
●Able to customize the system, as each unit has extension feature.
