Optimus™ DGA Monitor OPT100
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 gases
• No columns
• No filter wheels
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.
•The Optimus is shipped fully assembled and ready to be installed quickly - see our Quick Start 6-step Guide
•The Optimus uses a simple to use built in web based UI, no proprietary software to deal with – see the video below

Vaisala Infrared Technology - a system built to work in any environment
With over 25 years of experience designing and manufacturing IR sensors in our own in-house cleanrooms, we´ve proven our technology to work in the most extreme tempreratures and environments on the planet.
Vacuum Gas Extraction
Unlike all other DGA's on the market that use a headspace gas measurement which only accounts for approximately 30% of the gas in oil, Vaisala's proprietary vacuum gas extraction method actually uses the oil level as a piston to drive roughly 95% of the dissolved gas out of the oil. What's more, this method is independent of oil temperature, age, or type.
Computer and Comms - Proven Electronics
The Vaisala purpose built computer has a long history of success in weather applications around the world. A browser based interface means there is never any software to install or maintain on your servers.
Utilizing non-proprietary software means the OPT100 is compatible with any monitoring system on the market. We understand that DGA is just one piece of the overall deployment.
Standard communication protocols include MODBUS and DNP3.
The system was designed with modularity in mind such that should a component ever need to be replaced, it could easily be swapped out in the field. No need to ever send the unit back for service.
Power Supply - Separate High Voltage for Safety
The power supply is separated from the main cabinet to provide for a safe working environment. This cabinet also holds the three configurable relays.
This means any work on the main cabinet is in safe environment. This also reduces the complexity of any maintenance work that needs to be performed.
Robust Mechanics - Built to last
Each and every component in the OPT100 was extensively tested to reach expected 15 years lifespan. We used only stainless steel and marine grade aluminum for our components. We selected the most reliable magnetic gear pump on the market as opposed to a traditional diaphragm pump that contains seals which can fear out.
Using a fully hermetically sealed system with no venting to atmosphere we've created a completely seasled system eliminating any external source of contamination that could cause measurement interference or long term drift.
"In the not-so-far future, online DGA monitors will be deployed as standard equipment on all large transformers. This will open the door to automated monitoring of the grid and ultimately the development of smart grids with computer-assisted decision making."
