Tachometer Probe / Non‐contact Transducers

Non-contact transducers for measuring speed, velocity and displacement by Brüel & Kjær, such as our tachometer probe, designed to indicate the angular (rotary) speed - measured as revolutions per minute (RPM) - of a rotating shaft, like a vehicle engine shaft. In addition, with our Magnetic Transducer, you can excite a test structure using the transducer as a miniature contact‐free electromagnetic vibration exciter to determine the elastic properties of materials.
