Event data logger

code: S7841
Four-channel data logger is designed for record of two-state events. Values are stored to a non volatile electronic memory. Data transfer to the personal computer for further analysis is performed via USB, RS232, GSM or Ethernet interface by means of a proper communication adapter.

Logger Downloader - free application for data download from Android smartphones and tablet PCThe device includes Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.

For communication with the PC must be from Optional accessories ordered USB adapter, LAN adapter or COM adapter or start/stop magnet if is needed to control logging the other way than directly from computer.

Features

GSM communication

Applications:

  • record of door opening / closing
  • monitoring of functions of a machine
  • record of technological processes
  • record of running hours

 

Event logger advantages:

  • variability of PC connectivity - RS232, USB, Ethernet, GSM modem
  • permanent connection to the PC enabled, data is possible to download even during logging
  • large dual line display, switchable
  • robust case

  • low power consumption from battery, battery life up to 4 years
  • indication of remaining battery life, easy replacement of the battery
  • logging start/stop is enabled in several ways: at certain time and date programmed from computer, by delivered magnet or depending on logical state on channel 4 input
  • each logical state is possible to describe from the PC with the text of maximum 8 characters. Description is used on the list of the recorded values
  • each logger is possible to describe with text of maximum 32 characters
  • each channel is possible to describe with text of maximum 16 characters
  • password protection is enabled to prevent unauthorized manipulation with logger
