In addition to sensors permanently installed for continuous monitoring and control of large engines, there’s a need for sensors that can be used in combination with a hand tool to give an easy to use analysis of the combustion of each cylinder in a large motor.

The sensors are successively mounted on each indicator cock of a large motor for a short time to analyze the combustion in each cylinder. This information is used to manually balance combustion in the cylinders by avoiding so-called over-firing or under-firing and thus increasing the efficiency of the engine. By monitoring the individual cylinders over a longer period of time, typical damage can be detected early on and unplanned downtime can be avoided (condition based maintenance). This system, also known as MIP (Mean Indicated Pressure), is often used on motors which don’t have a separate indicator bore.

Similarly, the use is recommended for engines that are frequently operated using different fuel qualities, such as biogenic fuels or differing heavy oil qualities. MIP systems provide an ideal tool for use together with basic engine systems.

The GO51S is optimized for mobile indication using the MIP system. It is mechanically robust for frequent assembly operations, and not only has a high quality sensor function, but can be used as a heat sink as well, which reliably protects the high charge amplifier from overheating in hot environments. Additional practical features include a thermally insulated handle and a reinforced metal cable.
