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.

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.

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.

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.

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.

Messko

Pressure relief devices are protecting trans-formers against inadmissible and unsafe pressure surges. Once a specific predetermined degree of pressure has been reached, the pressure relief device will open, reduce the pressure, and tightly reseal itself after achieving the required reduction in pressure.

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

– 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

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 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)
