Graphtec GL240

Data Logger low-cost cu 10 canale izolate pentru tensiune, temperatura, umiditate, numarare impulsuri cu inregistrare pe Memory-Stick sau preluare directa pe PC

Data Logger low-cost, pentru măsurarea simultană pe 10 canale a temperaturii, umidităţii, tensiunilor, turaţiei/numărului de impulsuri sau a oricărui semnal de la un senzor cu ieşire în tensiune. Poate fi folosit la aplicaţii de laborator/industriale în care se preferă autonomia sistemului de achizitie, pentru înregistrarea datelor pe intervale de timp variate (de la minute la săptămâni):

  • Controlul condiţiilor de microclimat în hale, depozite, sere, camere de germinare, camere curate;
  • Calificarea OQ/PQ pentru camere climatice, testarea motoarelor termice, studiul conductivităţii termice al materialelor, testarea încălzirii echipamentelor electronice;
  • Înregistrarea evoluţiei mărimilor de proces în industria chimică, petrochimie, energetică (parametri reactoare, coloane de distilare, cazane, schimbătoare de căldură etc.).
Caracteristici notabile:
  • izolare “fail-safe” între canale,
  • înregistrarea datelor pe USB Flash Drive,
  • praguri de alarmare programabile pe fiecare canal în parte,
  • afişaj LCD color, interfaţă grafică prietenoasă,
  • achizitia de date se poate face in timp real pe un computer, - autonomie 6 h cu acumulatorul intern.

Sampling interval is limited by the number of channels in use.(10ms:1ch, 50ms:5ch, 100ms:10ch)

 

Ring capture function

The most recent data is saved when the memory is configured in ring memory mode. (Number of capturing data is 1000 to 2000000 points)

Relay capture function

Data is continuously saved to multiple files up to 2GB without losing any data until capturing is stopped when the memory is configured in the relay mode.

Hot-swapping the SD memory card

SD card can be replaced during data capturing when the sampling interval is 100ms or slower.

Displays the data by a bar chart (in firmware ver.1.10 or later)


The integrated data that is measured by the digital sensors can be displayed by a bar chart in the GL240 series.
