Digital Pressure Indicator DPI

Digital Pressure Indicator DPI



The Digital Pressure Indicator DPI measures dynamic pressures. It is designed to analyze the internal combustion curve of large two and four stroke diesel engines. The measurement is performed via an indicator valve.

It is a state-of-the-art MIP-system with a very convincing price-performance ratio. The high accuracy data collected by the DPI is essential for optimizing engines’ performance and reducing emissions. The self-explanatory handling of the Leutert pressure indicator allows even unexperienced operators to successfully take measurements in few minutes. The DPI software allows evaluation transmitting (to superintendency), archiving, and much more with only a few clicks.

The DPI is the most straightforward solution to reach optimum performance of your engine.
