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.

MM-0002
Discontinued: Magnetic Transducer
Designed to be used as a velocity sensitive vibration pickup or as an electromagnetic vibration exciter
-
MM-0012
The Photoelectric Tachometer Probe provides a very convenient transducer for triggering a portable stroboscope, such as Type 4912 where the range of motion is great enough,i.e., more than a few millimetres.
-
TYPE 2981
CCLD Laser Tacho Probe designed for contact-free speed measurements on rotating or reciprocating machine parts.
-
MM-0024
Designed for remote tuning and triggering of vibration measurement and balancing instrumentation in synchronism with rotating or reciprocating machine parts
-
MM-0004
Designed to be used in applications where mechanical motion must be detected without loading the test specimen
-
TYPE 2981-A
CCLD Laser Tacho Probe (high temperature fiber + adapator)
CCLD Laser Tachoprobe for contact-free, low- and high-speed measurements in hot engine compartments, up to 130 °C (266 °F).
