Data Logger Monitors Motor Run Times

Onset Computer has released the HOBO UX90 Motor On/Off Logger, a matchbox-sized, LCD-display data logger for monitoring run times of motors, pumps, compressors, and other equipment. The new logger records up to 340,000 equipment on/off cycle changes.

Using graphing and analysis software to convert recorded data into time- and date-stamped graphs, the HOBO UX90 is designed for a broad range of building performance monitoring applications, including HVAC/R systems diagnostics, compressed air systems monitoring, and general troubleshooting of motors, pumps, and fans. 

The logger attaches securely to motor housings via built-in rare earth magnets without any wiring, which eliminates the need for equipment lockouts. A large LCD screen visually confirms logger operation and a signal strength indicator ensures proper logger placement. 

Onset’s HOBOware software allows users to batch-configure and readout hundreds of loggers, as well as plot and analyze equipment runtime data. The HOBO UX90 is available in a standard memory model (UX90-004) capable of 84,650 measurements, and an expanded memory version (UX90-004M) capable of over 346,795 measurements.
