ENGINE INDICATOR Type 30 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 high pressure-change rates use type 30. For low pressure-change rates type 50 should be used and for extra high pressure-change rates use the indicator S1.
