Large engines need extra protection and future-proofing, given the high investment costs. Rotero therefore recommends the new SMX.pt-ea1 cylinder pressure sensors from STW. These help to improve fuel efficiency and optimise combustion, resulting in lower greenhouse gas emissions. At the same time, these cylinder pressure sensors monitor important engine parameters, thereby also preventing engine damage.
Reducing emissions is the primary objective
Reducing greenhouse gas emissions is currently the most important development goal in all areas of application for large engines. Think of ship propulsion, power generation, rail transport and gas compression. At the same time, digitalisation and trends such as remote monitoring and predictive maintenance require additional and increasingly accurate operating data.
Rotero understands the importance of accuracy and therefore turned to STW, a manufacturer based in Kaufbeuren, Germany, which specialises in automation components. STW has developed the SMX.pt-ea1 cylinder pressure sensors for use in fast, medium and slow-running large engines with a power range of up to more than 80 MW. These sensors are suitable for diesel, gas and dual-fuel technology.
Adjust cylinder force
As an engineer, you can install these sensors permanently, but you can also use them with portable single- and multi-cylinder meters for periodic measurements. When permanently installed, the sensors provide continuous data for advanced combustion control, monitoring and diagnostic functions. This enables fuel flexibility (multi-fuel). This allows you to optimise the entire combustion process and use fuel more efficiently, thereby directly reducing CO₂ and other emissions. To protect the engine and reduce wear and fuel consumption, these sensors can adjust cylinder power for smoother and more economical engine operation. Very ingenious.
Extremely demanding applications
The SMX.pt-ea1 sensors are equipped with STW’s own measuring cells based on thin-film technology. These measuring cells are known for their robustness, precision and long-term stability. What does that mean in concrete terms? It means that Rotero is delighted to supply you with these cylinder pressure sensors for a pressure measurement range up to 300 bar and a temperature range up to 400 °C at the diaphragm. With IP67 protection and an extremely robust connection cable between the sensor and the electronics, these are the sensors you need for the most demanding applications.
Economical and tailor-made
The cut-off frequency is 40 kHz and the signal processing speed is 128 ksps. At the same time, the SMX.pt-ea1 consumes less than 1 W of power. As with all STW components, Rotero can customise these cylinder pressure sensors to your specific requirements. Standard versions are available with M10x1 or M14x1.25 external threads.
Naturally, the SMX.pt-ea1 also supports intuitive configuration, application programming and diagnostics via the open-source software platform openSYDE. The new cylinder pressure sensors provide engine manufacturers and users with the right tools for future-proof combustion management of their latest large engines with multi-fuel support.
