The crank angle detection system consists of a crank angle sensor, a slotted disc, and a power supply box with a built-in amplifier. By simply attaching the slotted disc and crank angle sensor to the end of the engine's crankshaft, the rotation angle of the crankshaft can be detected accurately and with high responsiveness in engine performance tests and other applications.
It can be used as a timing signal for acquiring combustion pressure data within the cylinder in combustion analysis, and as an angle signal for measuring and controlling ignition timing.
We have prepared two types of pulses: one for TDC (Top Dead Center) detection (1 P/R) and crankshaft 360 P/R, and another for TDC (Top Dead Center) detection (1 P/R) and crankshaft 720 P/R.

Features

  • High performance, high precision

  • Its compact size and lightweight design provide exceptional vibration resistance.

  • Very fast frequency response

  • Ideal for various engine performance tests, such as combustion analysis.​

  • Simple setup; just attach it to the end of the engine's crankshaft.
