Instruments and controllers that measure, monitor or adjust velocity or speed in shafts, moving webs and other components.
Air Flow Sensors (272 suppliers)
Linear Velocity Sensors (72 suppliers)
Magnetic Speed Sensors (142 suppliers)
Magnetic speed sensors rely on a magnet as the sensing element or sensed target to capture rotational or linear speed. They are typically used as gear tooth speed sensors or incorporated into stroboscopes or tachometers.

Stroboscope Instruments (87 suppliers)
Tachometer Generators and Tachogenerators (58 suppliers)
Tachometer generators and tachogenerators are small AC or DC generators that output a voltage in proportion to the rotational speed of a shaft. They are capable of measuring speed and direction of rotation, but not position.

Tachometers (345 suppliers)
Tachometers are used to measure the velocity of a rotating object. They operate on the principle that a driven motor (i.e., a motor operated as a generator) produces a voltage that is proportional to the angular velocity of the motor shaft.
