Onset Computer Corporation (http://www.onsetcomp.com), announced a family of kilowatt hour (kWh) transducers for use with HOBO® data loggers.
The WattNode® transducers – manufactured by Continental Control Systems and sold directly through Onset – provide high-accuracy measurements of 1, 2, or 3-phase power in 2, 3, or 4 wire configurations. They connect directly to Onset's web-based HOBO U30 monitoring systems and standalone HOBO Energy Logger Pro™ data loggers, and are easy to install in service panels and junction boxes. Typical applications include energy monitoring, sub-metering, and phase-load monitoring.
For plotting and analyzing kWh data, Onset offers HOBOware® Pro software, an intuitive graphing and analysis software package for PC and Mac computers. HOBOware Pro provides a user-friendly graphical user interface that enables users to quickly and easily graph, analyze and print data files, as well as export the data to Microsoft Excel and other spreadsheet programs for further analysis.
The WattNode kWh transducers range in price from $270 - $295 and are available directly from Onset. Pricing information for HOBO U30, HOBO Energy Logger Pro, and HOBOware Pro software products can be found on Onset's website at http://www.onsetcomp.com.
