TachometerSignal

A tachometer signal is an electrical signal generated by a tachometer, which is a device used to measure the rotational speed of a shaft or engine. This signal is typically used in automotive, industrial, and aerospace applications to monitor and control the speed of rotating machinery. The tachometer signal is usually a pulse width modulated (PWM) signal, where the frequency of the pulses corresponds to the rotational speed. The signal can be analog or digital, and its characteristics, such as frequency, duty cycle, and voltage levels, can vary depending on the specific application and the type of tachometer used. Tachometer signals are often used in conjunction with other sensors and control systems to ensure the safe and efficient operation of rotating machinery. They can be used to trigger events, such as the opening of a fuel injector in an engine, or to provide feedback to a control system, such as an engine control unit (ECU). The tachometer signal is an essential component in many modern control systems, enabling precise and reliable monitoring of rotational speed.
