IMES to showcase next EPM generation

The company began series production of its EPM-XP electronic indicator in 2008, and IMES currently offers four different EPM types: EPM-Peak, EPM-XP, EPM-XPplus and EPM-XPplus-vibro.

All EPM devices are battery powered, compact and lightweight handheld devices for 2- and 4-stroke diesel engines. The devices are easy to use, and combine a high degree of accuracy with robustness. The devices remain accurate after years of operation, reducing the need for factory calibration.

More than 5,000 units have been sold up until now.

The measurements available to a user vary according to the EPM type being used. The digital peak pressure indicator EPM-Peak is designed to measure the maximum cylinder pressure while the engine analyser EPM-XPplus-vibro enables advanced combustion pressure measurements including vibro-acoustic diagnostic on 2- and 4-stroke diesel engines.

As a further refinement, all of the EPM Next Generation types share a common hardware system, enabling a simple upgrade from peak pressure indicator EPM-Peak up to engine analyser EPM-XPplus-vibro. The user can download a higher version from the Internet and it is not necessary to send the device back to IMES.

The collected data of all EPM types can be displayed and evaluated from the EPM visualisation software. Via USB port the device will be connected to a PC and the visualization software identifies the EPM type and activates the corresponding software functions. Depending on the instrument peak pressure, pressure- and combustion behavior, performance data as well as valve timing will be evaluated and analysed.

As an additional benefit, the software will automatically check if any hardware or visualisation software updates have been released while connected online. The user can install the updates free of charge.

Furthermore, the optimised handheld devices of the EPM Next Generation offer 2 additional function keys for an easier handling and a larger and more comprehensive display.

All devices of EPM family are equipped with the very robust cylinder pressure sensor HTT-06 that offers a very good thermodynamic performance and they all have a battery capacity of more than 20 working hours.
