tachometry

Definition

Noun (uncountable):
- The measurement of angular velocity: "tachometry" refers to the science or process of measuring the speed of rotation or angular motion of an object, typically using a device such as a tachometer.

Usage Examples

• (The measurement of angular velocity of the turbine.)
• (The process of measuring engine rotation speed.)

Advanced Usage

• "Optical tachometry": a method of measuring angular velocity using light beams or laser reflections.

  • Optical tachometry is preferred in high-speed machinery because it avoids physical contact. (A non-contact measurement technique.)

• "Digital tachometry": the use of digital sensors and microprocessors to record rotational speed.

  • Digital tachometry provides real-time data for industrial automation. (Electronic measurement of rotation.)

Variants and Related Words

• Tachometer (n): an instrument used for tachometry, measuring rotational speed.

  • The tachometer showed the engine was running at 3,000 RPM. (A device for measuring angular velocity.)

• Tachometric (adj): relating to or involving tachometry.

  • The tachometric readings were consistent with the manufacturer's specifications. (Pertaining to the measurement of angular speed.)

Synonyms

• RPM measurement: the determination of revolutions per minute.
• Rotational speed measurement: the process of quantifying how fast an object spins.

Related Idioms

• "Tachometry in the field": the practical application of angular velocity measurement outside a laboratory.
  • Field tachometry is essential for maintaining heavy machinery in remote locations. (Real-world measurement of rotation.)
