Current Dataloggers

Current Dataloggers (or Data Logger, Data Recorder, Data Acquisition) refers to electronics designed to capture current signals over time for study and review later.

Benefits of Dataloggers/Data Recorders
  • Quiet, unattended 24/7 operation
  • Simple to setup and operate. Many portable models available
  • Wide variety of measurement types and measurement speeds possible
  • Help troubleshoot and identify problems in many fields
  • Steady declining cost
Parts of a Current Datalogger/Data Recorder
current-datalogger
  • Included or accessory current clamps
  • A/D or analog to digital converter and signal conditioning electronics
  • Non-volatile storage memory for the collected data and a method to specify the storage rate and on some models the scan interval
  • PC Communications or other method to move the data to a computer and to configure the unit
  • Optionally a local display and keypad. Not always needed, so “blind” units are a cost saving
Considerations when purchasing a current datalogger
  • Single or three phase current
  • Max current and conductor size
  • Logging duration and interval
  • Sampling rate (some units may sample at one rate but log at a slower rate until a programmed alarm is tripped, for example)
  • CAT rating for safety
  • Neutral and ground current monitoring
  • Intermittent problem detection
  • Harmonic current monitoring
  • Measure voltage also
