Micropelt Industrial Sensors – mNODE

Micropelt mNODE

Micropelt mNODEs continuously monitors temperature in busbars and power distribution systems.

mNODE Infrastructure



The Micropelt mNODE is powered by inductive energy harvesting, converting stray magnetic fields into electricity, thus removing the need for batteries or wiring. Its compact design allows easy retro-fit for busbars, switchboards, motor control centres (MCCs) and other power distribution systems. Once installed it requires zero-maintenance thus minimising downtime.

The mNODE installation is easy to configure with Micropelt’s proprietary software. The software collects and analyzes sensor data of the electrical infrastructure using trend analysis. It therefore identifies defects at an early stage before major damage occurs.



Electrical Infrastructure Breakdowns


mNODE breakdown without



Permanent monitoring of temperature in electrical infrastructure enables early detection of defects before major damage occurs. Higher than normal temperatures are indicators for future breakdowns. Typical causes of infrastructure overheating include:

  • Bad junctions
  • Deterioration of insulation material
  • Corrosion of conductors
  • Breakdown of cabinet fans or air-conditioning
  • Overload through excess current
