Data Acquisition & Testing Services Limited

Data acquisition is measurement of the real world, to generate data that can be manipulated by a computer.  Sometimes known as Data Logging, DAQ or DAS, data acquisition involves digitally sampling signals and waveforms, then processing the signals to obtain desired information. 

 

The acquired or raw data is a series of measurements over time, from a transducer or sensor that converts a physical quantity such as strain, stress, temperature, pressure, displacement, relative humidity, light, noise, resistance, current, power, speed, vibration etc., into a voltage that is then converted by a digital to analogue converter (DAC) into a binary number.
