A tachometer generator is a sensor for measuring the __________

Explanation:
Tachometer generators convert the shaft’s rotation into an electrical signal that indicates how fast the shaft is turning. They’re designed to produce a voltage (or pulse frequency) proportional to rotational speed, making them ideal for speed sensing and control in engines, pumps, and motor drives. This isn’t about measuring flow, temperature, or pressure—those require other types of sensors. The tachometer output lets you monitor RPM, calibrate control loops, and detect speed changes to protect equipment or maintain proper operation.
