Fast data logger (1 MS/s) for voltage and temperature measurement with multi-function input on 8 galvanically separated channels with real effective value measurement
8 analogue multifunction inputs
The GL980 has an isolated input system, which ensures that signals are not affected by signal inputs on other channels. The multi-function inputs allow combined measurements of different measurement quantities such as voltage, temperature, humidity, logic and pulses.
- Measurement of high voltage and actual effective value according to CAT III
- Fast simultaneous voltage and temperature measurement with a sampling rate of 1 MS/s
- Voltage measuring ranges (BNC connection)
20 mV to 500 V DC, 1-5 V DC
10 mV to 250 V rms - Thermocouples (screw terminal connection)
K, J, E, T, R, S, B, N, W (WRe5-26) - Humidity: 0 to 100% RH (only with sensor B-530)
4 channels for logic/pulse/trigger
Four channels are available for logic and pulse input signals. The pulse mode can measure the following values for speed and flow: counter, pulses/sampling rate and revolutions per minute.
- Pulse: 4 channels * (counter, pulses/sampling interval and revolutions per minute)
- Logic: 4 channels *
* Cable B-513 is required. Pulse or logic can be selected
4 channels for alarm / trigger
Four channels are available for alarms. This also requires cable B-513.
Large, easy-to-read display
The GL980 has a large 7-inch colour display (800 x 480). Measurement data can be displayed in a waveform display or as digital values. Parameter settings can be checked on the screen.
Long-term recording of 4 million measurements per channel
Measurement value acquisition in the device's internal RAM and 4 GB flash memory, continuous measurement value acquisition up to a file size of 4 GB.
- Large internal RAM (4 million measurements per channel)
- External data recording on USB memory and SD memory card
Measurement duration
- Internal RAM (4 million measurements per channel) 4 seconds @ 1 µs interval; 46 days @ 1s interval
- Integrated flash memory (3.9 GB) 3.5 days @ 1 ms; more than 1 year @ 1s
- External memory (SD memory card / USB stick) 4 days @ 1ms; more than 1 year @ 1s
Standard software GL 980_2000-APS
- Automatic search for connected devices
- different display formats: YT curve, XY curve and digital values
- Support real-time data transmission up to a sampling interval of 1 ms (also from internal RAM).
- Acquired data stored in binary format can be converted to CSV format.
Operation and configuration
The buttons are ergonomically arranged for easy access and operation with gloves. Measurement signals are connected via a BNC bus or M3 screw terminals. Data recording can be started and stopped manually on the device, via an external trigger or time-controlled. The individually adjustable alarm output can be used to monitor the individual measurement channels and offers in addition to min or max. Configuration and data recording are also possible directly on the PC via a USB interface.
