What is a data logger?

A Data logger is a sophisticated device, capable of measuring just about any type of variable including light, humidity, density, current and temperature. These electronic devices record data over time or in relation to location. They are usually small, battery powered and portable. Sensors, internal memory and a microprocesser are components of data loggers.

What is the benefit of a data logger?

A huge benefit of using data loggers is to have the ability to collect data on a 24 hour basis. They can be left unattended to measure and record information for any given monitoring period.

What are applications of data logging?

Many applications exist for data logging. Only a few are touched upon here, for the list continues to grow as the instrument’s capabilities become known within different industries. Weather stations have a huge need for data loggers due to their ability to record wind speed, direction, temperature, relative humidity and solar radiation. Any hydrographic recording such as water level, water depth, water flow, water pH, and water conductivity can also be measured with data loggers. Soil moisture level recording and gas pressure recording are other measurements a data logger will monitor. The following list includes other useful applications for data loggers:

• Road traffic counting
• Measure temperatures of perishables during shipments
• Process monitoring for maintenance and troubleshooting applications
• Wildlife research
• Vehicle Testing

What can I use to both record and log information simultaneously?

The Amprobe DMII Pro Power Recorder/Logger is an example of a complete data logging kit. It includes four 1000 amp clamp-on current probes, four voltage leads with clips, RS-232 PC interface cable, software and an integrated hard case. The following features apply to this extremely useful instrument:

• Works with single and three phase systems (Y and delta)
• Capable of recording all parameters (single or three phase) simultaneously
• All readings are True RMS (TRMS)
• User selectable rates allow recording from one hour to several months
• Five built-in selectable languages: English, Spanish, French, German and Italian
• Readings and charts can be viewed on the DM-II LCD screen or downloaded to a PC
• Intuitive, very easy to use, Windows compatible PC software
• Line or battery powered
