Optimus™ DGA Monitor OPT100

Finally, the world’s first maintenance free multi-gas DGA Monitor requiring no consumables of any kind.

• No carrier or calibration gasses to monitor and replace regularly
• No internal column or measurement components to replace periodically
• No fixed filters/filter wheels, membranes or capillary tubes that will wear out and need repair or replacement

How is this possible?
Through the use of Vaisala’s patented non-dispersive infrared (NDIR) technology and patented vacuum gas extraction system we are able to achieve the best long term stability, reliability, and measurement performance on the market all with no false alarms and nothing to service or maintain.

Happy customers
“Over two years after installation we have had no problems with the equipment at all – no user intervention and no consumables have ever been needed.”
- Eduardo Briosso, Asset Maintenance Manager at CTM.

“We have compared the data from the OPT100 with our third-party professional offshore testing report and it has proven to be very accurate, so we know we can rely on its performance.”
- A person in charge at Dalian Company.

“The OPT100 gives us the ability to track any disturbance that may occur and extend the lifetime of our transformer, as well as reducing the possibility of any unplanned outages.”
- Keith Black, System Performance Senior Engineer at Scottish Power.

Key Benefits

A Monitor That Works Anywhere
Stainless steel pipes, IP66-rated, temperature controlled housing, as well as a magnetic pump and valves provide superb performance and durability – from the arctic to the tropics. There are also no consumables to service or replace.
No More False Alarms
The monitor’s IR sensor is based on Vaisala core measurement technology and critical sensor components manufactured in Vaisala cleanrooms. Vacuum gas extraction means no data fluctuation due to oil temperature, pressure, or type, while the hermetically sealed and protected optics prevent sensor contamination. The end result? A monitor that completely eliminates false alarms.
Intelligent Features for Hassle-free Monitoring
The monitor has a web-based interface that completely eliminates the need for additional software, and the device can be installed quickly – just connect the oil, power and data connections, and it’s ready to go. And in case of a disturbance like a power outage, self diagnostics allow the monitor to adjust itself.​
