Metrology Glossary: Tachometer
What Is A Tachometer?
A tachometer is an instrument designed to quantify the speed at which an engine rotates. It operates by detecting the number of complete revolutions the engine’s crankshaft makes in a minute and then conveys this data in the form of revolutions per minute (RPM). This device is useful for monitoring the performance and health of engines, as it provides a real-time measurement of their operational speed.
What Are Tachometers Used For?
Tachometers have a wide range of applications, from monitoring engine performance in vehicles such as cars, motorcycles, boats, and airplanes by measuring RPM to optimize gear shifting and troubleshoot engine problems. These devices are crucial for ensuring engines operate within their optimal range and identifying issues like over-revving or misfires. Furthermore, tachometers are utilized in industrial settings to monitor the speed of rotating machinery, enhancing performance and safety. In research and development, they are used in measuring the rotational speed of experimental setups and prototypes, aiding in the evaluation of new designs and technologies. Tachometers are also used in laboratories and testing facilities, where they measure the rotational speed of various objects, providing vital data for quality control and research purposes.
