www.messko.com Product Overview MESSKO

1911 Dr. Albert Hauser founds 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. 1925 Bourdon Spring At the early years the production was focused to manufacture radiator thermometers and pressure gauges for motor vehicles. In 1932 Messko developed the first thermometer with a Bourdon Spring. Today this reliable application is still the basis for Messko thermometers. 1935 The brand name Messko 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. essko dedicated to performance 1960 First Transformer Thermometer Messko 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. 1999 Subsidiary of MR Messko becomes the subsidiary of MR Maschinenfabrik Reinhausen. This strong partnership makes Messko one of the primary suppliers of measuring instruments for utility companies and industries worldwide. 2008 New facility Messko moved to the new large facility in Oberursel, Germany. All thermometers, oil level indicators, pressure relief devices and dehydrating breathers are produced here. 2011 Anniversary The Messko celebrates its anniversary. 100 years of experience and precision.

Moisture Maintenance Free Breather MTraB Watch your cost dry up MTraB Expansion vessel (conservator) of medium and large power transformers Expansion vessel (conservator) of on-load tap-changers Expansion vessel (conservator) of arc suppression coils Industrial applications DB100(HT) and DB100T(HT) Sensor-controlled heating system (condition/time) Output of the air temperature via analog output Self-monitoring with remote output control system Full protection against environmental influences LED indication of the current status Measured values can be called up through a RS485 interface Product description: In normal operation the air flowing to the oil conservator 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. DB200T(HT) 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 escapes from 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) DB200D-T(HT)
