The Crank Angle Detection System is composed of a crank angle detector, a slit disk and a power box with built-in amplifier. By mounting the slit disk and crank angle detector to the crankshaft end of the engine, it enables to detect the rotation angle required for various engine performance tests such with high accuracy and high response.
In combustion analysis, it can be used as a timing signal for collecting combustion pressure data in the cylinder, and as an angle signal for ignition timing measurement and control.
The output pulse is TDC detection (1 P/R), crankshaft 360 P/R and TDC detection (1 P/R), crankshaft 720 P/R available.
Features
High accuracy, high response
Weight and size reduction have increased the vibration resistance.
High speed of frequency response
Suitable for each engine performance test such as combustion analysis
Easy installation just to attach to the engine crankshaft end
