Temperature Alarm for Electrical Joints
improving safety, reliability and efficiency

What is PyrOptic? 
PyrOptic is an online temperature alarm for bus bar connections, cable joints and any other applications that are subject to unlikely, yet hazardous, thermal runaways events. 

​PyrOptic is an array of patent pending thermal actuators (PyrOnodes) that cut a plastic optical fibre core to signal an over temperature event. Loop continuity is monitored to detect for these activations.

PyrOptic provides highly reliable, 24/7 automatic monitoring at a far lower cost than intermittent, labour intensive, routine maintenance and inspection tasks.

PyrOptic removes people from the hazards associated with accessing electrical systems such as arc flash, electric shock, manual handing and poor ergonomics. Our system improves  workplace safety, equipment reliability and business efficiency.​
PyrOnodes operate on a simple thermal expansion principle 

Eliminate labour intensive routine inspections such as thermal imaging at a lower cost while providing 24/7 asset coverage.

Economical
  • PyrOptic is typically 1/20th the uninstalled cost of other online monitoring solutions. Unlike our competitors, we publish pricing on our website, see the product pages. 

Reliable
  • Connection failure is a hazardous, however generally rare occurrence. PyrOptic has been designed from the ground up to address the needs of this unique and specific application.
  • The temperature of a PyrOnode must achieve the temperature rating to effect physical transformation and the resultant forces required to cut the optical fibre. This eliminates the possibility of false alarms due to sensor malfunction.
  • The system topology virtually eliminates the need for individual sensor connections. 
  • Suitable monitoring relays are a standard, economical, multi vendor automation product that can be installed in a safe access zone. Should an alarm event occur correct relay function can be verified in seconds without any tools.
  • These features are in total contrast to alternative online monitoring systems that must collect signals over proliferous multi connection wired or wireless networks and then centrally process the data using expensive proprietary technology.

​​Versatile
  • PyrOnodes are sealed, rugged and small. This enables installation in tight locations and directly in oil filled equipment.
  • They can be attached using crimp lugs, clips, adhesives, heat shrink, tapes etc.​
  • Air gaps can be created in the optical loop eliminating any physical connection. This enables use in high voltage systems, withdrawable equipment and on the rotating parts of machine​s (such as rotor pole interconnections).

The Optimal Solution
  • PyrOptic catches emerging problems prior to catastrophic failure at a fraction of the price and complexity offered by alternative solutions.​
