The LEMAG® High Speed Indicator Type 25-M is used in cases where the speed of the engine is too high or the pressure rise is too steep for engine indicators type 30-M or type 50-M.
Due to it’s special construction it is possible to prepare diagrams for engines which are running at high speed. The extended pressure area allows measurements to be taken on engines up to 220 bar maximum pressure without having to chance the piston and cylinder.
