sDAQ Data Acquisition System
The sDAQ data acquisition system is designed for analyzing all necessary parameters of aerodynamics and fluid mechanics.
The 8-channel data acquisition module with a 14-bit resolution from National Instruments is the central element of the device. The in- and outputs of the device are ready to use for instant connection with the following sensors:
- 1x PT100 temperature sensor
- 1x eCTA hotwire bridge
- 2x ePressure differential pressure sensors
An internal barometric pressure sensor is additionally built in. Thus all essential parameters of subsonic examinations can be tracked and analyzed. All remaining analog inputs are connected to BNC sockets. The PC connection can be established by the built-in USB interface.
A simple data acquisition software is within the scope of delivery. The software provides the configuration of the data acquisition card, reading the measured values, conversion to physical values and the storage of all collected data.
The supplied software is written with LabVIEW 2010 and will be delivered as a stand-alone executable including its source code. Software adaptions according to the user requirements can be easily done based on the supplied software. This requires the NI LabVIEW 2010 software package which is not included.
