Cylinder pressure sensors are essential components for monitoring and optimizing marine engines. They measure the pressure in the cylinder during the combustion process and provide real-time data that fine-tunes engine performance and increases efficiency. These sensors make it possible to precisely analyze the combustion processes, which helps to reduce fuel consumption, minimize emissions and extend the service life of the engine. Cylinder pressure sensors are indispensable in modern shipping to meet the high demands of environmental standards and economic efficiency.
Robust piezoelectric sensors for diesel, gas and future-fuel engines
The Kistler piezoelectric pressure sensors, models 6613CG2 and 6613CG1, have galvanically isolated 4–20 mA output signals for continuous cylinder pressure monitoring in diesel and gas engines operating at medium and low engine speeds.
– Robust design, with excellent long-term stability
– Suitable for knock detection
– Very good thermodynamic behavior

Description
Area of application
Models
A robust fluoroelastomer cable connects the shoulder-sealed M10 × 1 sensor and the inline charge amplifier. The patented “antistrain” design makes the measuring element insensitive to changing installation conditions. The quartz measuring element is extremely stable and provides a very accurate and repeatable output signal over its entire service life. The sensor has been designed to achieve a lifetime of several thousand operating hours in diesel and gas engines, but its lifetime is highly dependent on the application.
Combustion control and monitoring tasks in the closed control loop, e.g. knock detection, cylinder balancing, p mi calculation, etc.
Type 6613CG2
This type is particularly suitable for 2-stroke engines <300 1/min, the inline charge amplifier runs with a time constant of >100 s which offers a fully suitable frequency bandwidth for all types of measurement tasks.
Type 6613CG1 (on request)
Recommended for 4-stroke engines, this type has a time constant of >10 s, which is suitable for all types of measurements for 4-stroke engines with >300 1/min.
