Multiplexer

Multiplexer allow a number of sensors to be measured by a single CR1000. The EAM416 multiplexer module sequentially multiplexes 16 groups of four lines or 32 groups of two lines at a time. Compatible sensors include vibrating wires, thermistors, thermocouples, potentiometers, load cells, strain gages, and soil moisture blocks.

Surge protector ESP-216

The input lines to the multiplexer can be protected against lightning induced high voltage transients using the ESP-216 surge protector card. Each ESP-216 card can protect up to 16 differential channels.

Multilogger Software

Multilogger software is a Windows based software for downloading and analysing data from CR1000 EDAS-10 data acquisition system. Each measurement channel can be configured for instrument type and programmed to output temperature corrected data in engineering units. Alarm limits can also be specified. The Multilogger uses the entered information to generate an appropriate datalogger program automatically. Multilogger includes a powerful data analysis tool comprised of a data editor, data selector, Excel compatible spreadsheet, report generator and charting tool.
