The EL-USB-4 data logger is a stand-alone 4-20mA data logger with direct USB interface. Designed for use throughout the process industry, the unit fits into a computer USB port for easy configuration and data download.
The unit has Windows-compatible software to configure the unit as well as the download and graphing of data. With the logger connected to a USB port, the software enables the user to set the required sampling rate (from 1 second), custom calibration, high and low alarms, and the logger start time. Once configured, the EL-USB-4 is removed from the computer, the cap is replaced, and the 4-20mA signal to be measured is connected to the logger via two screw terminals. At this point, logging can commence.
