AC Voltage Data Loggers and Sensors

Onset offers a range of AC voltage data loggers to help keep building equipment up and running optimally and ensure facilities are operating safely and efficiently. Select a cost-effective, easy-to-use voltage data logger that meets your needs from the choices below.

    EG4115

    The EG4115 Core is a 15-channel energy meter with 0.5% revenue-grade accuracy compliance and the ability to measure residential or commercial circuit panels, up to 3-phase 277/480VAC and 6900A. The meter has HomePlug AV powerline communication, an Ethernet port, and 2 USB ports for additional options, like WiFi. The embedded web server lets you connect to the interface over the internet or on a local area network. Each unit has a data logger that stores up to 64 data points for the lifetime of the hardware, and you can access data as granular as 1-second averages for the most recent hour of recording. The EG4115 Core is an accurate and flexible solution for monitoring multiple circuits in any residential or commercial energy monitoring application.

    EG4130

    The EG4130 Pro combines an energy meter, data logger, and a web server. This powerful combination lets you measure, store and retrieve (V, A, VAr, kWh, etc.) data directly from the device or from a remote location via the internet. You can view historical and live data for the lifetime of the hardware with the unit’s convenient user interface (UI). Users have access to real-time values, long-term reports, an interactive graphical interface, and many other tools.

    T-MAG-SPT-150

    The Magnelab 150-Volt AC Potential Transformer is used with the FlexSmart TRMS Module to provide accurate measurement of AC voltage. One or two PTs can be used with each FlexSmart TRMS module. This sensor offers an accuracy of ±1% (from 10% to 130% of rated voltage), but because this transformers ties directly into the line, it should be used only by qualified personnel.

    RX3000

    The HOBO RX3000, Onset’s most flexible remote data logging station, provides instant access to site-specific environmental data anywhere, anytime via the internet. The station combines the versatility and sensor quality of more expensive systems, an onboard LCD display, and the convenience of plug-and-play operation. The RX3000 is a configurable system (see "Configure System" tab below). 

    The RX3000 station is the basic component of the cost-effective and scalable HOBOnet Field Monitoring System for crop management, environmental research, and greenhouse operations.

    UX120-018

    Onset's HOBO Plug Load Data Logger is a high-accuracy, easy-to-deploy data logger that measures and records the power and energy consumption of 120V plug loads from office equipment, vending machines, and other devices.

    Accurate and Rugged

    The UL certified logger provides 0.5% measurement accuracy with a measurement resolution of 1 watt, making it an ideal choice for building audits where detailed energy use data is required. The rugged housing is designed to withstand the rigors of real-world handling, providing reliable performance despite bumps, drops, and use under desks.
