OVER 70 YEARS OF INNOVATION
In 1943, Per V. Brüel, developed the world's first commercial piezoelectric accelerometer from Rochelle salt crystals.
In fact, many of the accelerometers on todays market are based on technology invented by Brüel & Kjær.
Brüel & Kjær offers a broad spectrum of vibration measurement solutions that respond to varying needs and applications. In measuring acceleration, displacement and velocity, we provide a range of high-quality accelerometers, designed for specific environments, tasks and operating conditions.
Brüel & Kjær Accelerometer Types
A charge‐type piezoelectric accelerometer is robust and designed specifically for high‐temperature vibration measurement. The unique design of our charge sensors provide a high dynamic range, long‐term stability and ruggedness.
A CCLD accelerometer is designed specifically to make vibration measurement easy because the needed preamplifier is built into the accelerometer unit. It features low impedance output enabling the use of inexpensive cable and can drive long cables.
An industrial accelerometer - with its rugged design - is both robust and reliable and covers a wide range of permanent vibration monitoring applications including operations in wet, dusty and potentially explosive areas.
Important Specifications When Choosing Accelerometers
When selecting your accelerometer, please consider the following specifications according to your test application and environment.
Does the unit selected have sufficient dynamic range for the measurement in question?
What are the maximum and minimum acceleration levels
Is the unit linear across the required measurement range?
What is maximum and minimum temperature that the unit will be used at?
Watch this video for a quick overview what to look for when choosing accelerometers!
