Vibration transducers

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.

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.

Based on the Fiber Bragg Grating (FBG) technology and the newLight optical sensor line, the FS65 accelerometer is a high-precision vibration sensor tailored to measure acceleration at different frequencies from 0 to 50Hz.

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 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.

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.

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.
