Instruments and controllers that measure, monitor or adjust velocity or speed in shafts, moving webs and other components.
Velocity Sensing Categories
Air Flow Sensors (257 suppliers)
Air velocity flow sensors measure air velocity or volume flow using insertion probes or capture hoods.
Linear Velocity Sensors (67 suppliers)
Linear velocity sensors measure the linear velocity of an object using either contact or non-contact techniques.
Speed Sensors (152 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 (86 suppliers)
Stroboscope instruments are used for inspection and observation of moving parts by freezing or slowing down the action of an object.
Tachometer Generators and Tachogenerators (45 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 (320 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.
Zero Speed Switches (27 suppliers)
Zero speed switches are devices used to detect stoppage of a rotating shaft. They typically have one or more relays.
