Tachometers

Tachometers

DC tachometer generators provide a convenient means of converting rotational speed into an isolated analog voltage signal suitable for remote monitoring and velocity control applications. Tachometers are particularly suited in precision integrator and velocity servo applications, both of which require a highly linear speed/voltage relationship with minimum ripple. The nearly pure dc output-with no phase shift-allows tachometers to be used as velocity feedback transducers for fast-response servos and other devices. DC tachometers are also excellent rate generators for velocity damping in low speed position servo applications. Contact us today for a quote.

Advantages of Tachometers

  • Have linear characteristic
  • Temperature compensation is easily achieved
  • Can generate high voltage in a small size
  • Polarity of induced voltages indicates direction of rotation of the shaft
  • Conventional DC type voltmeter is used for measuring the induced voltage
  • Ideal in control or measurement applications which require directional indication

Tachometers Frequently Asked Questions

What is a tachometer and what are its uses?

A tachometer is an instrument used to measure the rotation speed of a shaft or disk. Tachometers are powered by tachometer generators and can be used to monitor engine and motor speed, and corresponding speed of powered equipment like conveyors, mixers, and machine tools. They are often used as feedback devices in speed control circuits.

How does a tachometer generator work?

Modern tachometers use a rotating armature to measure rotational speed. The armature rotates within a fixed magnetic field, inducing electromotive force proportional to the shaft’s speed. The armature contacts are connected to a voltmeter circuit, which converts the voltage into a speed value. Tachometer generators power tachometers and output a voltage proportional to their shaft speed.
