Tinytag Energy

The Tinytag Energy Logger is a portable, non-invasive solution for monitoring single and three-phase power supplies in commercial and industrial settings. Designed for simplicity, the unit features a self-configuring setup—once the flexible Rogowski coils are clipped around conductors and the voltage lead is connected, the logger automatically detects the wiring configuration and begins displaying real-time values. It is an essential tool for energy managers looking to troubleshoot equipment, meet ISO 14001 targets, or perform “before and after” efficiency audits. Unlike standard loggers, it includes an on-device display for spot checks and a “Record” button to start logging sessions without needing a PC on-site.

Features

  • Easy to use
  • High Accuracy
  • Small, Portable and Lightweight
  • Single and three phase monitoring
  • Records Voltage, Current, Power and Power Factor
  • Non-invasive Voltage and Current Connections
  • Record for Six Weeks (5 Minute Logging Interval)
  • Can be Started Without a Computer
  • Magnet For Hanging on Metal Panels

The Three Rogowski Coil Options

To accommodate different cable sizes and tight distribution boards, the system utilises flexible Rogowski coils (all rated up to 2,000A AC RMS) available in three distinct internal loop diameters:

  • Standard Coil (85mm diameter): Supplied with the TGE-0001 Kit. The versatile, go-to option for standard three-phase incoming mains cables and larger industrial machinery supplies.
  • Large Coil (175mm diameter): Supplied with the TGE-0002 Kit. Designed specifically for thick, heavy-duty busbars or heavy trunking feeds found in primary substation or whole-facility monitoring.

  • Small “Tear-Drop” Coil (38mm diameter): Supplied with the TGE-0003 Kit. Perfect for tightly packed electrical panels, isolated machinery connections, or smaller individual phase conductors where space is limited.

The Tinytag Energy logger is supplied in a carry case with three current coils, UK and EU mains leads, a USB cable, a copy of the Tinytag Explorer software and a user manual.

Please note: the Tinytag Energy Logger is only for sale in the EU and Australia.

Applications

Performing "Before and After" monitoring to prove energy savings following the installation of new machinery or LED lighting.
Gathering the long-term energy usage profiles required for environmental management certifications.
Identifying peak demand times to help businesses shift high-energy processes to off-peak hours and reduce "Maximum Demand" charges.
Finding "hidden" energy waste, such as equipment that remains powered up or idling unnecessarily overnight.

Frequently Asked Questions

â–¶ Q: Can the logger record energy data using only its internal batteries?
A: While the unit has a 60-day battery backup for the display and current logging, it should be plugged into the mains for accurate energy monitoring. Connecting the mains lead allows the logger to measure actual fluctuating voltage values, which is essential for calculating true kWh rather than relying on a fixed, estimated supply voltage.
â–¶ Q: What is the benefit of the Rogowski coils over traditional current clamps?
A: The flexible Rogowski coils are non-invasive and "clip-on," allowing them to be easily looped around thick or awkwardly shaped conductors without breaking the circuit.
â–¶ Q: Does the software automatically calculate the cost of electricity?
A: Yes, the Tinytag Explorer software allows you to input your specific utility tariff rates to automatically convert the logged kWh data into actual financial costs for energy audits.
â–¶ Q: Can I hire the Tinytag Energy Logger for short-term projects instead of purchasing?
A: Yes, we offer these units for hire on a weekly basis, providing a cost-effective solution for one-off energy audits or short-term power monitoring projects without the need for capital investment.
â–¶ Q: Are the Rogowski coils included in the hire kit?
A: Yes, our hire kits are supplied as complete "ready-to-go" systems, including the logger, three non-invasive flexible coils (85mm), and all necessary software and download cables.

Weekly Hire Option

If you only need to run a short-term spot check, troubleshoot a temporary power supply issue, or conduct a one-off energy audit, you don’t need to purchase the equipment outright.

Weekly Rental: Omni Instruments Ltd have three TGE-0001 kits on our hire fleet and you can hire the Tinytag Energy Logger on a flexible, weekly basis. The hire unit arrives as a complete inside a rugged pelicase, fully equipped with all three standard current coils, UK mains leads, a USB cable, and the tracking software. It is ready to plug in and start logging right out of the box.
