GL840WV

Withstand Multi-Input Datalogger

  • 제조사:GRAPHTEC (JAPAN)
  • Model:GL840WV (B-565 withstand module장착)
  • Max. Input:DC 300V p-p
  • DC 정확도:± 0.05% of F.S. + 10uV
  • 온도정확도:± 1.1 ºC (K type at 100ºC)
  • :배터리 측정에 적합한 고전압사양

Three types of input system enable to measure various phenomena

Input system 1 : Multifunction analog input ports

 

Contains a highly isolated input system which ensures that signals are not corrupted by noise from other channels. The GL840's inputs are suitable for combined measurements 
from voltage, temperature, humidity, logic, and pulse signals.

The standard configuration has 20 analog input channels. It is expandable to 200 channels by adding optional 20 channels extension terminal base unit (B-566) and input
terminal units (B-564 or B-565).

 

 

 

Withstand voltage & Accuracy Multi-input type (B-564) Withstand-voltage type (B-565)
Voltage Input voltage range 20 mV to 100 V 20 mV to 100 V
Max. voltage (Input - GND) 60 Vp-p 300 Vp-p
Temp. Thermocouple R, S, B, K, E, T, J, N, W (WRe5-26)
RTD (Resistance Temp. Detector) Pt100 (IEC751), Pt1000 (IEC751), JPt100 (JIS)
Accuracy Voltage ± 0.1% of F.S. ± (0.05% of FS + 10μV)
Temperature* ± 1.55 ºC ± 1.1 ºC

* Accuracy rating for K-type thermocouple at 100˚C includes reference junction compensation. Accuracy varies by temperature levels and thermocouple types.

The following shows how a standard configuration is expanded to more than 40 channels

GL840 series carries two SD memory card slots

SDHC up to 32 GB supported. Captured data can be stored in GBD (Graphtec Binary Data) 

 

or CSV file format.

 

 

Capturing time* (when all 20 analog channels are being used with Logic/Pulse inputs turned off).

*Figures are approximate. File size of captured data is 2GB in GBD or CSV file format on this 

 

 

chart. Sampling interval is limited by the number of channels in use

 (10ms:1ch, 50ms:5ch, 100ms:10ch). Limited sampling speed is available 

when digital sensors and GL100-WL are used as a remote monitoring device.
