Onset Hobo UX120 Pulse Logger energy data logger

The Onset Computer Corporation Hobo UX120 Pulse Logger is a versatile, 4-channel energy data logger that combines the functionality of four separate data loggers into a single compact unit.

The pulse logger enables energy-management professionals - from energy auditors to building commissioners - to easily track building energy consumption, equipment runtimes, and water and gas flow rates. It can simultaneously measure and record pulse signals, events, state changes and runtimes, and is capable of storing up to 4 million measurements, enabling longer deployments with fewer site visits.

The product is suitable for energy-monitoring applications where fast deployment and a range of energy measurements are needed. For example, while the logger is monitoring power use on one channel, it can independently track gas flow on another, pump runtimes on another, etc.

Users can start and stop the logger via software or push-buttons, and set the logger so it continues to log/overwrite data when the memory is full. It also provides diagnostics via onboard LEDs to assure logger operation which aids the installation process, and enables high-speed data offloads via its USB 2.0 interface.

The Hobo Power Logging System, which merges the Hobo UX120 Pulse Logger with Onset’s E50B2 Energy and Power Meter, provides a comprehensive energy and power monitoring solution. The flexible system can measure and record power factor (PF), reactive power (VAR), and watt hours (Wh) and a variety of other parameters. Additionally, it accepts voltage ranges of 90 - 600 VAC, current ranges of 5 - 32,000 A, and can be used for both single and three-phase monitoring applications.

The Hobo UX120 Pulse Logger and Hobo Power Logging System are compatible with the company’s Hoboware Pro 3.2 software, which combines powerful graphing and analysis capabilities with an optimised interface for configuring logging options and sensors.

The Hobo UX120-017 Pulse Logger is available in standard and expanded memory versions.
