Temperature Alarm for Electrical Connections

What is PyrOptic? 
PyrOptic is a permanent, online temperature alarm for electrical connections. Distributed sensors called PyrOnodes cut an optical fibre in response to abnormally high temperatures. This loss of optical continuity is used to signal an over temperature event.

PyrOptic has achieved reliable, round the clock connection monitoring at the lowest cost by understanding the failure modes and optimising a solution to address these requirements. 

PyrOptic replaces intermittent thermal imaging and routine offline inspections with a safe, highly efficient and vastly more effective solution. 

PyrOptic can be deployed in difficult locations such as inside oil filled equipment, on rotating parts of machines and inside bus ducts.
Economical
  • PyrOptic is the most cost effective online temperature monitoring solution for electrical connections.
  • Due to low cost, PyrOptic can be practically deployed to protect everything from low voltage moulded case circuit breakers through to high current bus bars. 
Reliable
  • Based on the thermal expansion of an inert material, PyrOnodes never require calibration and can be relied upon to alarm decades after installation.
  • This same principle eliminates false alarms as a PyrOnode must achieve its temperature rating to cut the optical fibre. 
  • Suitable monitoring relays are a commodity product ensuring protection against obsolescence, high reliability and low cost.
​​Versatile
  • Virtually any number of PyrOnodes, be it one or hundreds can use the same optical loop (200m length limitation typical)
  • PyrOnodes are sealed, rugged and small enabling  installation in tight locations and directly in oil filled equipment.
  • PyrOnodes can be attached using crimp lugs, clips, adhesives, heat shrink, cable ties, tapes etc.​
  • Optical lens can be used to beam the light path across air gaps ranging from mm to over 10m. This allows application in high voltage systems without any tracking risk and even on the rotating parts of machines.​
