Maintenance, testing and commissioning
Millivoltti Oy offers maintenance, testing, and commissioning services for various process automation measuring instruments. We have been operating in the industry since 2008. Regular maintenance and testing ensure the accurate operation of industrial measuring systems, reduce fault situations, and extend the lifespan of the equipment.
Maintenance of industrial measuring instruments
We perform periodic maintenance and upkeep work on process automation measuring instruments. We service the equipment at industrial sites in accordance with the manufacturers' instructions and the customer's maintenance program. Proactive maintenance minimizes unexpected process downtime and ensures the continuous reliability of measurement results.
Testing and commissioning of automation equipment
To ensure the functionality of measurement operations, we perform comprehensive testing and commissioning work. During commissioning, we check the operation of measuring circuits, alarm limits, and the signal flow from the field device to the automation system. Testing verifies the technical condition of the devices and ensures that they react to process changes correctly.
Versatile equipment expertise
Our maintenance, testing, and commissioning services extensively cover the following process automation measuring instruments:
- Pressure measurement (pressure transmitters and pressure switches)
- Level and temperature measurement (level switches, level and temperature measuring instruments, and transmitters)
- Gas measurement (residual oxygen measuring instruments and flue gas measuring systems)
- Water analysis measurement (conductivity, pH, dissolved oxygen, silicate, and sodium measuring instruments)
Experience in partnership and subcontracting projects
Millivoltti Oy operates in installation, commissioning, testing, and commissioning work both independently and as a subcontractor. We have worked in cooperation with several different companies, including ABB Oy, Insta Automation Oy, Bilfinger, Caverion, Siemens Osakeyhtiö, PCS-Engineering Oy, Primetals Technologies Finland Oy, and Outotec/Metso Outotec/Metso Oyj.
