How To Measure Engine Speed: Sensors, Signal Processing, And Applications

Engine speed measurement is crucial for monitoring and optimizing engine performance. It involves utilizing sensors like tachometers (contact and non-contact) to detect and quantify the rate at which the engine's crankshaft rotates. The measurement process entails signal processing and interpretation, including duty cycle analysis and noise rejection techniques. Accurate engine speed measurement is essential for diagnostics, control, and optimization applications, as it provides insights into engine health, performance, and efficiency.
