Datalogger Product Description |
The GL500-2-1 Datalogger
is the latest addition to Global Water’s line of rugged remote dataloggers.
The dataloggers feature two analog channels and one digital channel for
recording data, as well as monitoring battery voltage. The datalogger
records over 81,000 readings and has four unique recording options: fast
(10 samples per second), programmable interval (1 second to multiple years),
logarithmic, and exception. Start and stop alarm times can be programmed
to synchronize multiple dataloggers, delay sampling until a preset time,
or limit the number of recordings during a day. The dataloggers are available
for computers with either a RS-232 serial communications port (GL500S-2-1
version) or a USB port (GL500U-2-1 version). |
Remote
Monitoring |
| The GL500-2-1 dataloggers can monitor two 4-20mA sensors (0-5 volt inputs are available as a factory option) and features a scalable digital input that accepts switch closure signals from rain gauges or relays, as well as pulses from various external monitoring and control devices. The datalogger provides switched power to the sensors based on the programmable sample interval and sensor warm up time settings. 2-wire and 3-wire sensors can be quickly connected to the datalogger’s internal terminal strip and calibrated via the Global Logger software. The GL500S-2-1 Datalogger Serial Communications version can be accessed through dial-out to a remote modem attached to the serial communication port. |
Software
|
| The GL500-2-1 dataloggers include Global Logger II Windows software and PDA software, which allow for easy setup, calibration, upload, and transfer to a spreadsheet program using a laptop, desktop, or PDA. The Global Logger II Windows software has online help files that are easily accessed using drop down menus and links to quickly find the answers to your questions. |

| Datalogger Software Information |
| The Datalogger includes Global Water
Datalogger Software, Windows-based software that provides many useful
features, such as real-time readout, measurement interval and engineering
unit selection, station ID setting, and sensor calibration. The software
makes accessing recorded data and setting options easy. Data downloaded
from the datalogger can easily be opened in any PC spreadsheet program
for analysis and graphic presentation. Globlal Water's Datalogger Software
will run on a PC-type laptop or desktop computer running Windows 98 or
later. To communicate with the Datalogger, a standard RS232 serial cable
for the GL500S-2-1or a USB Type B cable for the GL500U-2-1 is required.
Purchase of the datalogger includes the appropriate communication cable
(for communication between the datalogger and your computer). |
