HIGH SPEED 1 MS/S SIMULTANEOUS SAMPLING WITH ISOLATED INPUTS

midi logger Graphtec GL2000 High Speed Simultaneous Sampling Isolated Input.jpg

GL2000 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 measurement.

SIMULTANEOUS SAMPLING
GL2000 utilizes simultaneous sampling to eliminate slowdown in sampling rate by using multiple A/D converters in simultaneous sampling method. Four individual A/D converters in each channel sustains the maximum sampling speed for all four 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 WITH CAT III MEASUREMENT CATEGORY

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

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.

 

 EXAMPLE:

CH2 = CH3 * CH1   (CH2 is a value obtained by multiplying the values of CH3 and CH1)
* Value of calculated results are displayed and saved into data file.


ALARM FUNCTION & SIGNAL OUTPUT

Threshold of an alarm can be set for each channel. When an alarm occurs, notification is sent by following methods.

ALARM THRESHOLD

Analog input: High, Low, Window-in, Window-out
Logic input: H or L (signal in each channel)
Pulse input: High or Rising, Low or Falling, Window-in, Window-out


 WHEN ALARM IS DETECTED

  • Display to screen (Digital value of alarm's origin channel is displayed in red)
  • Save alarm information to measurement data file
  • Output alarm signal
    Number of channel: 4 channels (Output channel can be arranged to each source channel in OR condition.)
    Signal type: Open collector (pull-up to 5 V with 10 kΩ resistor), maximum load is the 24 V and 100 mA.
    * Requires Input/Output cable for GL series (B-513 Option).

OTHER HELPFUL FUNCTIONS

 

Delivers reliable measurements out at a location with unstable power supply.

Equipped with three types of options for power source, AC adapter, DC input, and battery pack. With a battery pack, GL2000 runs continuously for approximately 3 hours. If an AC power failure occurs, it will automatically switch from the AC adapter to the battery pack. Additionally, when the voltage of the battery pack reaches low, measurement is automatically stopped after saving the data file preserving the accumulated data. (Requires two battery packs (B-569 option) installed.)
