Vibration transducers

Our range of vibration transducers includes accelerometers, force transducers, impedance heads, impact hammers, tachometer probes, vibration calibrators, cables and accessories.

CCLD (IEPE) accelerometer

CCLD accelerometers are PE charge accelerometers (also refereed to as IEPE accelerometers) with integral preamplifiers that have output signals in the form of low impedance voltage output. Most HBK CCLD accelerometers are hermetically sealed to protect against environmental contamination, they have low susceptibility to radio frequency, electromagnetic radiation and low a impedance output due to the built-in amplifier. This allows the use of inexpensive, and long, coaxial cables.

Charge accelerometer

A charge‐type piezoelectric accelerometer is robust and designed specifically for high‐temperature vibration measurement. The unique design of our charge sensors delivers a high dynamic range, long‐term stability, and ruggedness.

Fiber Optic Accelerometer

High precision accelerometers based on Fiber Bragg grating (FBG) technology for safe and long-term vibration measurements at low frequencies.

Force transducers

Brüel & Kjær force transducers (also refereed to as piezoelectric force sensors) are designed with integral electronics for structural dynamic testing. The transducers feature a very high resonance frequency, that allow for measurement of short duration, fast rise force transients. All our DeltaTron Force Transducers are individually calibrated, and deliver patented technology for applications within dynamic, compressive and impact force measurements.

Reference accelerometer

Reference Standard Accelerometer designed for measurements in vibration calibration laboratories. The reference accelerometer is typically used for comparison as the "Reference Standard" or by substitution, as the working standard accelerometer.

Impulse hammers / impedance heads

Impact hammer and impedance head measurements are often conducted in difficult environments where dust, temperature fluctuations and high humidity frequently pose severe demands on the electrical and mechanical integrity of the instrumentation. All HBK impact hammers have been meticulously designed to meet the expectations for reliability in all such environments.

With the ability to excite from the smallest of structures to various civil engineering structures, HBK has an impact hammer to suit even the most demanding application.

Tachometer probes

Non-contact transducers for measuring speed, velocity and displacement by HBK, 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.

Vibration calibrators

Our portable vibration calibrator provides accurate acceleration, velocity and displacement calibration of accelerometers, and general instrumentation. The calibrator is handheld, battery-powered and an essential tool for everyday use in changing environments.

Cables

Cables for electrical connectivity to our instruments are specially designed to obtain low noise signals and more accurate responses from our instruments. Always use HBK cables to interconnec our sensors with the ancillary electronics.
