Voltage Datalogger

Voltage Dataloggers (or Data Logger, Data Recorder, Data Acquisition) capture voltage 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 Voltage Datalogger/Data Recorder
voltage-datalogger
  • Voltage jacks
  • 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 voltage datalogger
  • TRMS capability
  • Monitor cycle frequency and duration
  • 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 safety rating
  • Intermittent problem detection
  • Harmonics
