Electronic Pressure Indicators
IMES electronic pressure indicators are designed as compact and lightweight handheld devices for diesel- and gas engines.
They are easy to use and convince with their accuracy and their sophisticated analysing software.
Since 2008 the electronic indicator EPM-XP is in series production. Up to now we offer 4 different EPM types:
The user can purchase a licence file for an upgrade to a higher version. He can load the file via the visualisation software on the device.
All EPM devices are equipped with the very robust cylinder pressure sensor HTT-06 that offers a very good thermodynamic performance and they have a battery capacity of more than 20 working hours.

Up to now we offer 4 different EPM types:
EPM-Peak is designed to measure the maximum value of cylinder pressure on 2- and 4-stroke diesel engines.
The EPM-Peak collects 10 consecutive pressure measurements (cycles) and calculates peak pressure and engine speed. The measured data are displayed in numerical format on the LCD screen and stored in memory.
In comparison to conventional mechanical peak pressure meter the EPM-Peak offers an easy handling, the measurements have a higher accuracy, the data Pmax and speed will be displayed exactly on the LCD screen and up to 5 engines @ 20 measurements / engine can be stored. It is not necessary to list the measurements directly.
Optional we also offer a licence file to enable the Pmax balancing diagram in the visualisation software.

EPM-XP is designed for periodic monitoring of cylinder pressures on 2- and 4-stroke diesel engines. It provides important measurement data for engine diagnostics and condition monitoring directly at the point of use.
For further analysis, the visualisation software provides p/alpha diagram incl. Pcomp calculation with advanced algorithm for TDC correction and Pmax- and Pcomp balancing diagram.

EPM-XPplus was a further development of the electronic indicator EPM-XP for advanced combustion pressure measurements.
EPM-XPplus offers the same functions as the electronic indicator plus advanced features to enable an optimised engine performance:
EPM-XPplus offers the same functions as the electronic indicator plus advanced features to enable an optimised engine performance:
- IPOWER, IMEP calculation
- Determination of ignition start
- Trending diagram
- Open and save reference measurements
- Direct data transfer to IPE (IMES performance evaluation software)
EPM-XPplus-vibro offers the same functions as the EPM-XPplus. The additional vibroacoustic sensor gives more detailed diagnostics as it provides the signal of injection and valve timing (intake valve open/close, exhaust valve open/close, fuel injector open/close). With help of the vibroacoustic data you can determine for example defect in fuel injectors, fuel pumps, valves and defects in oil injectors of cylinder lubrication.
EPM-XNGplus is designed as a compact, lightweight and affordable handheld device, specially tailored to periodic cylinder pressure monitoring and output balancing on the types of gas engines found in North American natural gas pipeline compressor stations. It employs technology well proven on diesel and gas engines in marine propulsion and power generation applications, adapted to two-stroke gas engines with rated speeds from 40 to 500 rpm and four-stroke gas engines with rated speeds from 200 to 1500 rpm.
The EPM-XNGplus device offers the accuracy and ease-of-use typical of electronic measuring technology from IMES, plus a scope-of-supply that includes sophisticated analysis software.
As well as immediate readouts of peak cylinder pressure on the EPM-XNGplus display, customers can download recorded data to PC running software specially designed by IMES and Morris Control Systems for visualization, analysis and storing of data. Special features include compiling 50-cycle peak pressure histories for each engine cylinder, as well as peak pressure and balancing charts, and the ability to generate engine balance reports in Excel or PDF formats.
