Below is a list of Data Acquisition Systems manufacturers from Ottawa, Illinois. Data acquisition systems are used in order to convert analog waveforms into digital values that can be used for processing. This conversion is possible due to the process data acquisition (DAQ) which is the sampling of actual physical conditions such as property or phenomena, which can include light intensity, fluid flow, gas pressure, temperature and force. The resulting samples are then converted into digital numerical values by means of sensors in order to get all of the data into a unified form that can be utilized by a computer.
