New USB data loggers simplify the capture of process readings. One example is the family of USB sticks from Lascar. Simply insert one of these loggers into the PC’s USB port. Name it, choose the sample rate, memory mode, hi/lo alarms (if needed) and start mode. Once configured, the logger can be removed from the computer to start & log independently. While logging, the optional LCD display shows the status or latest reading. When finished, plug it back into the PC for one-click data download & display, using the supplied software. Export the data for further analysis.
The SimpleLogger II family from AEMC operates in a similar manner but offers a larger memory (up to 240,000 readings) and additional functions, such as TRMS AC.
Stand-alone loggers often include a display for setup and data display. The Lascar GFX family is IP67/NEMA 4X rated and stores up to 256,000 readings. A micro USB port allows PC setup and data download.
