High-speed isolated 8-ch multifunction

Model: GL980

Graphtec GL980 midi LOGGER
High Speed 1MS/s Datalogger with Voltage and Temperature Measurement Isolated simultaneously 8 channel data logger.

Main Features:

High speed 1 MS/s simultaneous sampling with isolated input

GL980 is equipped with an isolated input mechanism to protect signals from interferences caused by noise from other channels. 16-bit A/D converter adopted to achieve hi-speed and hi-resolution measurements.

Simultaneous sampling
>GL980 utilizes simultaneous sampling to eliminate slowdown in sampling rate by using multiple A/D converters in simultaneous sampling method. Eight individual A/D converters in each channel maintain the maximum sampling speed for all eight channels to measure high speed rapid voltage fluctuation and multi-channel vibration measurement.
Sampling interval: 1 µs to 1 min (in steps of 1, 2, 5)
External sampling function
>Sampling of the logger is performed in sync with an external device using an external signal input.
Maximum input frequency: 100 kHz * B-513 Input/Output cable for GL is required.

Multifunction input

Voltage, temperature, humidity, logic and pulse measurements can all be taken simultaneously in high speed.

Measure repetitive waveforms such as vibration with instantaneous value and effective value.
>Measures either instantaneous value or effective value (RMS). By utilizing the trigger feature to measure abnormal spikes in the continuous waveform, users can measure vibration abnormalities repeatedly.
Measures abnormalities in a repeated waveform by effectively measuring the corresponding RMS value.
>All RMS measurement range with Crest Factor: up to 2
Scaling (Engineering unit) function
>Measured voltage value can be converted to a specified engineering unit. The value can be displayed with the physical measurement value of the sensor and be saved into the data file with the converted values.
Calculation function between channels
>Four arithmetic operations (Addition, subtraction, multiplication and division) are available using two analog input channels.
* Data can be saved only in GBD file format.
Trigger function
>The trigger in this unit has multiple functions including trigger level of input signal value for each channel.
Alarm function & signal output
>Threshold of an alarm can be set for each channel. When an alarm occurs, notification is sent by the following methods.

Large Easy-to-read 7-inch LCD

Monitor data in multiple methods in addition to digital value display and full waveform display screen.

YT waveform monitor screen
>Displays data with analog waveform and digital value. Screen can also be split into 1, 2, 4 or 8 zones to display the channels in different zones.
Digital monitor screen
>Displays current data in digital value and results of real time statistical calculation. (Function: Maximum, Minimum, Peak-to-peak, and Average)
When displays only current data, it can be shown in 1, 2, 4 or 8 zones.
Past waveform monitor screen
>Display the past part of the data while capturing data. Execute without stopping measurement and also scroll past data. Data screen can be switched with past and current.
XY graph monitor screen
>Emulates the classic XY chart recorder. Also supports features for pen up/down and position movement.
