High-speed isolated 8-ch multifunction

Model: GL980

Graphtec GL980 midi LOGGER High Speed 1MS/s Datalogger with Voltage and Temperature Measurement Isolated simultaneous 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 interferrences 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 sustains 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 level trigger 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 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.

• Y-T 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.
