Dual channel logger with pulse and binary input

code: S7021
Data logger is designed for record of pulses and 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 communicationMain applications of pulse data logger:

  • record of pulses from water meter, gas meter, electrometer, flow meter, revolution counter
  • time event record from binary signal (e.g. door opening/closing .. )
  • production monitoring
  • long term field measurement

 

Advantages of pulse data logger:

  • counter reading is possible to display in real value, range of the LCD display is 19999, after exceeding of displayable value only lowest places are displayed
  • two modes are enabled: after counting of maximum value counter stops or overflows and counts again, counter reset enabled from the PC
  • in the record is possible to indicate counter state or counter state increment between logging intervals
  • record from binary input contains date and time (resolution of 1 s) when change of input logic level appeared and its logic state
  • record from binary input can be disabled
  • it is possible from the PC to assign both logic states of binary input a description, which is displayed on the record – on the LCD logic states are always displayed as ON ( contact closed) and OFF (contact opened)
  • variability of connection to the computer - USB, RS232, Ethernet, GSM modem
  • permanent connection to the PC enabled, data is possible to download even during logging
  • dual level alarm is enabled for counting input, alarm is indicated by blinking of the value on the LCD display
  • low power consumption from battery, easy replacement of the battery
  • logging start/stop is enabled: at certain time and date programmed from computer, by external signal connected to binary input or by delivered magnet
  • also special logging mode is enabled, when logging runs only, if counter value is out of adjusted alarm limits
  • input pulse signal is recalculated and displayed in real measured physical units by means of the PC software
  • extremely low consumption from the battery, indication of remaining battery life, easy battery replacement
  • robust watertight case, easy installation, locking enabled
  • 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
