May 2, 2005—Onset Computer Corporation has introduced two low-cost battery-powered data loggers for monitoring runtimes of a broad range of equipment, such as HVAC/R systems, pumps, and industrial process tools.
The new HOBO U9 Motor On/Off and HOBO U9 State loggers record up to 43,000 equipment on/off cycle or state changes, and use Windows-based software to convert the recorded data into time- and date-stamped graphs to demonstrate how efficiently equipment is running, or help users identify cycling problems.
According to Onset, the Motor On/Off logger easily attaches to motor housings without any wiring, which in turn eliminates the need to lock out the equipment being monitored. The State logger can be wired to any contact closure or passive relay switch. Both models include a user-replaceable lithium battery, which offers reliable operation for up to one year.
To analyze and plot equipment usage data, Onset offers HOBOware 2.0 for Windows, a powerful graphing and analysis software package. HOBOware provides a user-friendly graphical user interface that enables users to easily determine the total percentage of time equipment was in use, peak hours of operation, runtimes, and on/off cycles.
