ALTA Industrial Wireless AC Current Meter

ALTA industrial wireless AC Current Meters measure the RMS current of an alternating current (AC) system using a current transformer (CT) that wraps around the "hot" wire of a two wire (hot, common, ground(optional)) power system. The sensor reports Minimum RMS current, maximum RMS current, average RMS current, and amp hours to the iMonnit system.

Information

ALTA industrial wireless AC Current Meters measure the RMS current of an alternating current (AC) system using a current transformer (CT) that wraps around the "hot" wire of a two wire (hot, common, ground(optional)) power system. The sensor reports Minimum RMS current, maximum RMS current, average RMS current, and amp hours to the iMonnit system. The iMonnit system is capable of generating watt hour or kilowatt hour readings as well.

Product Features

  • Measures amp hours, max RMS current, min RMS current, and average RMS current. 
  • Capable of generating Watt Hour or Kilowatt Hour readings using iMonnit. 
  • Data logging for accumulated amp hour readings. 
  • Can notify based on current levels or changes in current levels. 
  • Measures current from 0 - 20 Amps.

* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
