In this millenium, chart recorders are becoming very digitized; actual “paper” based charts are being replaced regularly. A digital chart can also print to paper (beit Z-Fold, circular, roll, etc.) but the real value of these newer recorders is that they can possess graphical screens which can show the process data in various formats and resolutions. Secondarily, the chart recorder stores the digital trend information for up to about 30 days (depending on the size of the internal memory) and then allows the data owner to ‘dump’ the data to a flash drive or download it to his internal network via Ethernet cable or wireless connection.
