What is PyrOptic? 

PyrOptic is a permanent, online temperature alarm for detecting electrical connection failure. 

Distributed sensors called PyrOnodes cut an optical fibre in response to abnormally high temperatures. A simple relay monitors for loss of optical continuity to provide a system alarm. 

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

Economical

• The most cost effective online temperature monitoring solution for electrical connections
• Practical for both low and high value applications
• Manual and automatic monitoring options 

Reliable

• Thermal expansion of an inert material underlies the simple principal of operation
• PyrOnodes will outlast the connections they protect
• False alarm virtually impossible
• Relays to support online monitoring are a commodity product

​​Versatile

• Hundreds of PyrOnodes can use the same optical loop 
• PyrOnodes are sealed, rugged and small​​​ making them suitable for tight locations and inside oil filled equipment.
• PyrOnodes can be attached using cable ties, adhesives, crimp lugs, P clips, heat shrink and tapes​
• 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 on the rotating parts of machines.
