Leutert Engine indicator

The mechanical pressure indicator type 50 measures dynamic pressures. It  is especially designed to analyze large two stroke Diesel engines.
 

Leutert engine indicators are used on Diesel engines, gas engines, air  compressors, pumps, etc. A metal stylus draws a clear pressure-path  diagram which records the pressure curve within the engine cylinders as  influenced by the piston stroke. The recording drum can be moved by  means of a string, which is pulled manually or by the engine. If the  drum is driven by the engine, the diagram may be planimetered. Our  indicators are designed to cover various ranges of speed and rates of  pressure-change.
