Temperature Monitoring for Electrical Systems
improving safety, reliability and efficiency

What is PyrOptic?

PyrOptic is a temperature monitoring alarm suited for use with electrical equipment

​PyrOptic is an array of patent pending thermal actuators that cut a continuous optical path to signal an over temperature event. The optical path is made of a high temperature plastic optical fibre and the cutting mechanisms known as PyrOnodes harness the expansion of an engineered thermal actuation material.

PyrOptic can play a key role in reducing the frequency and scope of routine maintenance and inspection tasks while at the same time delivering superior risk mitigation outcomes at a lower cost. The end result is increased workplace safety, equipment reliability and higher business efficiency.

Key features of PyrOptic open the technology to the majority of electrical connections and contacts, even those found in oil filled equipment. PyrOptic is as effective in low voltage installations as on the main bus systems in a gigawatt generation plant. No other technology currently exists that can offer such real world versatility at such an economical price.
​

PyrOnodes are a self contained over temperature alarm that operate on a simple thermal expansion principle ​

Eliminate thermal imaging and provide 24/7 asset coverage at a lower cost.

Economics

• PyrOptic is typically 1/20th the uninstalled cost of other online monitoring solutions. Even thermal imaging windows are more expensive, and that's not including installation and then the ongoing routine inspections and reporting over the life of the asset.   

Number of connections​​​​

• Electrical assets are full of connections, even relatively small switchboards can contain hundreds of them. PyrOptic can both practically and economically achieve comprehensive coverage to effectively manage risk. 

Probability of failure​

• Electrical connections are highly reliable. PyrOptic embodies this fact and leverages the mechanism of permanent disruption to signal hazardous yet uncommon events. This key feature results in massive benefits in terms of economy, system reliability and scalability. Virtually all other solutions act like process sensors, forcing the end user to adopt needless complexity and expense.

Reliability 

• Connection failure is quite a rare occurrence, the chance of an electronic monitoring system failing is probably greater and that's a fundamental problem. We recognised this at PyrOptic and designed a system that’s virtually bullet proof to ensure it will outlast the equipment it protects. 

What you really need to know

• PyrOptic catches a developing problem before permanent damage occurs. Alternatively you could pay 20 times more for a significantly more complex solution to  achieve the same result and with a bit of luck it may also last 5 years past the manufacturers warranty. 

Unlimited voltage application range

• By using send and receive lenses in the optical loop air gaps can be created eliminating  any physical connection. Even where the fibre optic can be directly applied such as in medium voltage applications, the user may choose this option to eliminate the introduction of potential tracking paths due to contamination over time. 

Versatility

• PyrOnodes are sealed, rugged and small. This enables installation in tight locations and directly in oil filled equipment. In addition, the high temperature POF features a Nylon 12 outer jacket, a material with extremely low moisture absorption and high chemical resistance.

Moving equipment

• The ability to transmit the light path across air gaps can also be used to create loops between stationary and moving parts. For example, withdraw-able switch gear can contain a PyrOptic loop requiring no physical connection to the main switchboard where the monitoring relay is contained. Even temperature monitoring on rotating equipment can be achieved (loop integrity checked twice per revolution).
