Shipping Industry Applications

Piston telemetry from MANNER Sensortelemetrie GmbH has become an important tool for the development of pistons, for the verification of their strength and for the optimization of the lubrication process. The systems record the temperature values at important points on the piston online in several channels. Exact data regarding the temperature distribution can be obtained for various load scenarios. From this data, important conclusions can be drawn for the optimum design of the pistons or their operational stability.

The systems work with robust thermocouples that effortlessly withstand the increasing degree of vibration and are easy to install. The temperature-resistant electronics scan the measuring points with each piston stroke. The collected values are transmitted contactless and battery-free to a stationary evaluation unit.

In addition to the thermal influences, it is also the mechanical stress that leads to increasing loads on the piston. The working pressure acts on the piston surface and is distributed over the entire component. Two-stroke pistons must also cover or open the inlet, outlet and overflow channels, i.e. they must control the gas exchange. In addition to the thermal effect, this entails an additional mechanical load.

In order to obtain an exact analysis of the mechanical load within the piston, MANNER has been optimizing sensor telemetry for this measuring task for many years. The distribution of the forces on the individual regions of the piston is particularly important. The proven advantages of MANNER sensor telemetry also apply here:

MANNER Sensortelemetrie GmbH supports partners worldwide in the online recording of single or multi-channel valve temperatures on the engine. We are in constant contact with the corresponding competence teams, especially for large engines such as those used in shipping. Our systems work with robust thermocouples which effortlessly withstand the high accelerations and are easy to install.

The sensor telemetry amplifier from MANNER is integrated into the valve plate where it processes the data from the desired temperature measuring points. A stator antenna can be mounted at a generous distance, picks up the measured values without contact and transmits them to a stationary evaluation unit. It does not matter whether the valves rotate during operation. The digital coding with 16 bits guarantees highly reliable data security. A characteristic feature is that no continuous signal contact between the two antennas is required.

Auch andere Komponenten des Antriebsstranges von Schiffen, wie beispielsweise Getriebewellen, werden zunehmend mit den Messsystemen der MANNER Sensortelemetrie GmbH versehen, um Wirkungsgrad und Effizienz der kostenintensiven Anlagen zu optimieren.

Profitieren auch Sie von unseren fortwährenden Aktivitäten zur Erforschung und Entwicklung neuster Messmethoden mittels der Nahfeld-Telemetrie. Dabei können Sie sich auf unsere langjährige Erfahrung bei Messapplikationen an Komponenten des Schiffsantriebes verlassen.

The bearing at the connecting rod head or connecting rod eye is exposed to very high loads, especially in large engines. Combustion pressures and operating masses affect the plain bearings in the form of pressure and friction. The connecting rod bearings play a decisive role in reducing these loads, which is why adequate temperature measurement can often be necessary.

With the extremely high forces that occur at the connecting rod eye, temperature measurements in the bearing are useful and often indispensable from several points of view. MANNER Sensortelemetrie GmbH offers you solutions with non-contact measurement data transmission to provide you with optimum support in the following tasks:
