Data acquisition DAQ magic


From ensuring production quality to predicting operational failures


data for characterisation, monitoring or control purposes. They can be used to measure a variety of different physical parameters - including temperature, pressure, vibration, sound, voltage, current, acceleration, strain, light intensity, RPM and flow rate. Also, they can instigate the taking

s we are all well aware, data acquisition (DAQ) systems gather useful measurement


of specific actions based on data that the system receives, such as sounding an alarm, halting a production line or simply turning on a light.


Among the most critical uses of


DAQ hardware are concerning upholding output quality in manufacturing facilities, and monitoring the condition of machinery to anticipate the need for maintenance work (thus avoiding


potential downtime that could have serious cost implications associated with it). The specific parameters of these applications will dictate the resolution, accuracy and channel count, as well as the speed requirements for the DAQ system. As the manufacturing and industrial

processing sectors strive to increase efficiency levels, reduce costs and consistently yield higher quality products, the need to monitor a broad range of parameters using a multitude of different sensors is driving the development of more advanced DAQ hardware and supporting software. Similarly, companies managing fuel/water pumping stations or power substations also need to monitor not just the performance and state of their equipment, but also the environment within their facilities to ensure optimal operating conditions are kept to.
