2008New facilityMessko moved to the new large facility in Oberursel, Germany. All thermometers, oil level indicators, pressure relief devices and dehydrating breathers are produced here.

1960First Transformer ThermometerMessko successfully opens a new market with the development of the first measuring instruments for transformer engineering. The foundation for a whole series of measuring instruments for power supply companies is created.

1925Bourdon SpringAt the early years the production was focused to manufacture radiator thermometers and pressure gauges for motor vehicles. In 1932 Messko developedthe first thermometer with a “Bourdon Spring”. Today this reliable application is still the basis for Messko thermometers.

1911Dr. Albert Hauserfounds the fine mechanical institute for precision scales and weights. He produces scales for laboratories, the precious metals industry and colleges which offer extreme measuring precision.

1935The brand nameMessko Hauser is created from the German words for measuring and monitoring. It was entered and protected as a trademark. Messko celebrates huge success with measuring instruments for the automotive industry.

Messkodedicated to performance

1999Subsidiary of MRMessko becomes the subsidiary of MR Maschinen-fabrik Reinhausen. This strong partnership makes Messko one of the primary suppliers of measuring instruments for utility companies and industries worldwide.

RS485 interface

Product description:In normal operation the air flowing to the oil conser-vator has to pass the silica gel and is dried on the way. The humidity of the air in the pipe line is continually measured by a moisture sensor and the results are sent to the electronic controller.

When the humidity of the air in the pipe line exceeds a selected value, this is a sign that the silica gel is unable to absorb any more moisture. In this case the self-regulating heating element inside the silica gel container is activated. The water vapor that escapesfrom the silica gel condenses on the specially shaped bottom casting and drips out of the filter-system.

MTraB® at a glance– Extensive economies, as you leave out maintenance interventions and desiccant

replacements (Asset management)– Increasement of operating reliability for your transformers and on-load tap-changers– Reduction of life-cycle costs– No pollution and disposal problems with the used-up desiccant– Easy replacement (Retrofit)
