Every company knows that the first step to reducing costs is identifying energy waste. An electrical data logger is a useful instrument that you can use to find hidden energy waste and save significant energy costs. While nameplates on equipment and statistics on utility bills can be helpful, they are not enough to determine what equipment and practices are leading to high energy use.
By monitoring your company power or energy usage over time you can greatly increase the performance of your facility. Similar to tracking your car’s kilometres per litre fuel consumption rate, assessing your whole-facility power usage can give an alert to future problems and performance changes. Analysing the data collected by the electrical data logger will provide you better opportunities to achieve energy savings or help you verify the effectiveness of an implemented energy efficient system.
Furthermore, the data collected within your facility can be used for the purpose of benchmarking a company to make the comparison to another work environment easier or to try the chances of load or response shifting strategy. Plus, the connection between weather conditions and a company energy use can be created by using electrical data.
Electrical data loggers are available in different sizes, shapes and designs. The prices of these devices tend to vary depending on the complexity of technology they feature. The simplest models of electrical data loggers are much more economical than the models that can handle a variety of different inputs.
Compact and hand-held electrical data loggers are powered by batteries and feature an internal microprocessor, one or more sensors and data storage. These devices can be either stand-alone single units with internal sensors, small enough to fit a basic hand palm, or multi-channel data collection instruments with multiple external sensors. Some models may also be suitable for use in other applications.
While a data logger is considered a stand-alone device it needs to be connected to a computer and specific software for analysing the collected data. This stand-alone characteristic of this testing equipment involves an on-board memory that is used to store acquired data. Some models feature large memories to accommodate various days, or even months, of unattended recording.
Electrical data loggers come also with different types of data graphing and analysis software packages. As a rule of thumb, you should look for software that is Windows® and MAC-based. The software should allow you to easily and quickly perform tasks such as launching the data logger, configuring parameters and offloading data.
