IMES is a privately owned company founded by Stefan Neumann in 1996. It based in the town of Kaufbeuren, in the picturesque Allgäu region of Bavaria, Southern Germany. IMES specializes in electronic measurement, monitoring and testing of cylinder pressure on engines and compressors, based on its high precision TION thin film pressure sensors.

IMES counts all the world’s major engine manufacturers among its customer base and IMES sensors, electronic pressure indicators and combustion monitoring systems are employed on a wide range of diesel, gas and dual-fuel engines, on ships and locomotives and in power and cogeneration plants and pipeline compressor stations all around the world.

Extremely robust cylinder pressure sensor for thermodynamic control concepts on high efficient gas engine


The IMES GmbH has been developing a new type of very robust cylinder pressure sensor. Stefan Neumann, CEO of IMES will present the high robust sensor (HRS) during CIMAC congress on 11th June 2019.

The developments of new 2- and 4-stroke gas engines are increasingly penetrating into operating areas which require a very precise knowledge of the current state of the combustion process in each cylinder for reliable control and monitoring concepts. The closed loop combustion control (CLCC) has become established in a new generation of gas engines and enables a very high engine efficiency even by using various types of fuel.

Due to the trend to higher indicated mean effective pressure (IMEP) on small, medium and large gas engines with speed ranges of 100…1800 rpm, the required cylinder pressure sensors are subject to increasing operating- and environmental conditions.

Thus a new era for extremely robust and high accurate cylinder pressure sensors with long-term stability has started...
