  The Harvy2 ROGOWSKI LoRaWAN IoT sensor differs from the Harvy2 only in the measurement inputs; it is characterised by:


  • Practical acquisition of:

​- Effective power,

​- Effective energies (meter readings),

​- Effective currents,

​- Power factors,

​- Reactive power,

​- Apparent performances,

​- Mains voltages,

​- Mains frequency.


  • Three inputs for Rogowski coils, which can have advantages over current transformers due to their large measuring range, bendability and very low weight.
  • Free choice of electric phases.
  • One input for a voltage transformer (for voltage signal and power supply of the sensor).
  • Highly innovative electronics (patent application pending).
  • Ideally suited for stationary or mobile use.
  • Simple installation (plug-in system); no cable pulling.
  • Optional practical magnetic holder for metal surfaces.

  • LoRaWAN sensor for recording measured values in supply networks for alternating and three-phase current;
  • Use with deZem Rogowski coils;
  • Input channels 1 to 3: 0-800mV AC;
  • Input channel 4: 0-250 mA AC;
  • Self-powered due to integrated "energy harvesting" on channel 4 (no battery required);
  • A galvanically isolating deZem voltage transformer must be connected to input 4;
  • LoRaWAN v1.04, class A device, worldwide operation: EU868, US915, AU915, IN865, KR920 and AS923 (not yet CN);
  • USB-C for configuration, firmware updates, display of measured values, fast charging;
  • JST connector system for deZem-Rogowski coil and voltage converter;
  • RJ45/4xJST adapter cable included in the scope of delivery;
  • Rogowski coils and voltage transformers as well as extension cables not included.

Accessory products

As standard, the Harvy2 ROGOWSKI is used with three deZem Rogowski coils for up to 1,000 A or up to 3,000 A each. A deZem voltage transformer with integrated current limiter is required to record not only the effective currents but also the active power, power factors, reactive power, apparent power, mains voltages and the mains frequency, and to supply the Harvy2 ROGOWSKI with a constant supply of energy. Only connect the voltage transformer to the 4th input of the Harvy2ROGOWSKI. deZem offers voltage transformers with Euro plugs or for mounting on top-hat rails.
