HOBO 4-Channel Pulse Data Logger

 

 

 

 

 

 

 

Description

The HOBO UX120 Pulse Data Logger is a highly versatile, 4-channel energy data logger that combines the functionality of four separate data loggers into one compact unit. It enables energy management professionals – from energy auditors to building commissioners – to easily track building energy consumption, equipment runtimes, and water and gas flow rates. The HOBO UX120 Pulse Data Logger is available in a standard memory model (UX120-017) capable of 500,000 measurements and anexpanded memory version (UX120-017M) capable of over 4,000,000 measurements

Feature

• Simultaneously measures and records pulse signals, events, state changes, and runtimes
• Stores up to over 4 million measurements, enabling longer deployments with fewer site visits
• Maximum pulse rate – 120 Hz
• Pulse input range – 0 to 24VDC
• Streamlines deployment via a range of start/stop options, logger status LEDs, and high-speed USB 2.0 data offload
• Works with Onset's Energy & Power Meter to measure Power Factor (PF), Reactive Power (VAR), Watt Hours (Wh) and more. Learn how.
  The T-VER-E50B2 Energy and Power Meter outputs (3) sets of pulses which are logged by the UX120-017. These pulses represent Watt-hours, Amp-hours, and VAR-hours. HOBOware software uses these pulse values to calulate AC Current, AC Voltage, kW, Power Factor, VARs, and VA. The formulas used in these calculations can be found here: 14993-A-Derived-Channels.zip
• Compatible with HOBOware and HOBOware Pro software for logger setup, graphing and analysis
