Electronic Pressure Indicator

Electronic Pressure Indicator



The Electronic Pressure Indicator measures dynamic pressures. It is especially designed to analyze large two and four stroke Diesel and gas engines. The main application area is the marine market and mobile and stationary power stations. The Electronic Pressure Indicator is a powerful and easy-to-use high quality electronic engine indicator which can be characterized by its long life components.

The Electronic Pressure Indicator has gone out of production 2017.
It is replaced by the DPI.

The measuring method of the Electronic Pressure Indicator is fast and simple: The pressure sensor is temporarily connected to the indicator valve (connection W27 x 1/10”). While the measuring series is being recorded, the data can be read off the LC display. After that, the data sets are saved to memory and can be transferred to the PC. The data may be evaluated and administered with the DPI software.
