Introduction
The GL980 from Graphtec is a high speed portable data logger that samples on all eight channels simultaneously.
Simple to Setup
Setting up the GL980 is simple and can be done via the front panel and display on the unit itself or via the dedicated software that is supplied with every data logger.
With a 17.7 cm (7") display, the GL980 can be easily setup in the field or on a bench top without the need for a computer and data then can be transferred to PC via USB or SD card memory devices.
Software
The freely supplied software can used to quickly and easily set up the GL980, it also supports real-time data capture, data replay, X-Time and X-Y display/recording, Fast Fourier transform (FFT), and direct to Excel function.
Isolated Analogue Input Channels
Eight isolated channels can measure voltages from 20 millivolts up to 500 volts via BNC type connectors. In addition, the GL980 has eight separate screw terminals which can be used for thermocouples, 4-20mA current loops etc. Humidity can also be measured with the optional B-530 humidity sensor.
Digital I/O
With four digital I/O logic and Pulse channels, the GL980 can record on/off events or count pulses from a range of instruments.
Simultaneous Sampling Speed
Typical data loggers multiplex channels into one Analogue to Digital converter, however the GL980 has eight Analogue to Digital converters and can simultaneously sample and record data at speeds up to 1MS/S or 1μs on all eight channels.
Example of 8-channel analogue measurement
| Capture destination | 1μs | 100μs | 500μs | 1ms | 10ms | 100ms | 1s |
| Internal RAM | 40 sec | 400 sec | 33 min | 66 min | 8 hrs | 4.5 days | 46 days |
| Internal flash 3.9 GB | x | x | x | 54 hours | 22 days | 225 days | Over 1 year |
| External memory 4 GB | x | x | x | 59 hours | 24 days | 245 days | Over 1 year |
All times are approximates only.
Real-time monitoring
Data can be viewed in real-time with the Graphtec GL980-APS GL Connection software that is supplied with every unit or data can also be viewed via the GL980's built-in web sever.
Remote data transfer
Remote data transfer across a Local Area Network(LAN) or Wide Area Network (WAN) is a great way to access your data remotely. The GL980 can be connected to various ADSL, Cable or 4G modems with a TCP/IP network ports allowing the the GL980 to be viewed anywhere around the world over the internet. A Virtual Private Network(VPN) also can be set up for data security if required.
Manual data transfer
Data can be recorded to the internal memory of the GL980 or directly to an external USB memory device. The data file format can be recorded in Comma Separated Variable(CSV) so it can be opened directly with Excel or in a Graphtec Binary Data(GBD) format to protect your data. The GDB format can then easily be converted to Excel with the Graphtec GL980-APS software.
Data Logger or Data Acquisition
The GL980 is a true Data Logger in that it can operate as a stand alone unit and does not require a computer to record data. But with sampling speeds of up to 1MS/s, the GL980 can also be consider as a portable Data Acquisition unit.
Just add the sensors
The GL980 is supplied with all basic items to get you up and running in no time. Just add a mix of signals or sensors and you will be recording great data in no time at all.
Standard items
- GL980 midi-LOGGER
- GL980 Quick Start Guide.
- GL980-APS Software.
- Power Supply - 24 Volts DC.
- USB Cable.
Conclusion
If you are looking for a bench top or portable data logger that can sample at 1MS/s simultaneously on eight channels and measure voltages up to 500 volts, then the GL980 is the data logger for you. Like all Graphtec products, the GL980 is will built and well equipped with data logging features.
To compliment the hardware is a nicely thought about GL Connection software package.
