Thermometers are built to last
Messko thermometers still fully functional after 45 years.
Humboldt, Tenn., November 3, 2010—Messko, a division of Maschinenfabrik Reinhausen GmbH, offers thermometers that are built to last. Three of Messko’s thermometers were found to be in perfect working order since their installation 45 years ago. In 2009, Argentinean company Tadeo Czerweny S.A. completely overhauled a 40-MVA transformer dating back to 1964. During the overhaul, three Messko type MZ-HK160 Oil Temperature Indicator (OTI) thermometers were checked for functionality. The result: all three thermometers were still fully functional.
Gustavo Savino, service manager at Tadeo Czerweny S.A, said “We also checked the thermometers during the repair work on the transformer. The three Messko thermometers are still working perfectly, and there was absolutely no need to replace them with new devices.”
It was revealed that not only have the thermometers been functioning properly for 45 years, but also none of them have ever been recalibrated since their original installation date. The three OTI gauges were only superficially cleaned and are now back in use on the newly overhauled transformer.
