MJK Chatter ® Battery Powered Data Logger With Modem

 
 
  • MJK Chatter ® Battery Powered Data Logger With Modem for monitoring and measuring of, among other things, level where no permanent power supply is available.
  • Contains a built-in multi-channel data logger, a GSM/GPRS modem including a battery which ensures more than 5-year life time on the battery for one call a day.
  • Transmits data over the internet to a Microsoft SQL data base by means of the integrated GPRS modem.
  • Alarm notifications through SMS. 
  • Housed in an impact-proof aluminium and plastic casing for mounting directly on bore holes and sounding borings where sensor, electronics and antenna are protected from vandalism.
  • In this configuration log- and call intervals can be preset.
  • Meanwhile the entire system is in hibernation mode, practically without using any electricity.
  • At the chosen log- and transmission time the Chatter awakens, measures and transmits the data.
  • Such a wake up can be as briefly as 10-15 seconds, with means the battery can last more than 5 years.
  • Available in an IP 67 / NEMA4 polycarbonate cabinet for wall mounting with a 230/115 V AC or 10-30 VDC supply. 
  • Analogue, digital and modbus inputs, a connection of new as well as existing measuring units is possible. 
  • To save electricity, Chatter® only supplies the connected transmitters for the time the measuring takes place, typically less than 10 seconds per measurment.
  • By choosing the Modbus connection, measurement signals are transferred to Chatter® with a maximum resolution, since there is no analogue-to-digital signal handling involved in the circuit.
