BARSPRING ENGINE INDICATOR Type S1 SYSTEM MAIHAK 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: For extra high pressure-change rates use type S1. For high pressure-change rates type 30 should be used and for low pressure-change rates use type 50. Features Minimum reciprocating mass Piston, cylinders and springs are detachable and interchangeable Easy to handle, simple to operate Rugged design	The mechanical pressure indicator type S1 measures dynamic pressures. It is especially designed to analyze and adjust 4-stroke large diesel engines.  Downloads: DATASHEET
