Accelerometers for Vibration Measurement

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

Charge Accelerometers 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. Available in single axial and triaxial configurations.

CCLD Accelerometers 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.  Available in single axial and triaxial configurations.

Industrial Accelerometers 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. Charge and CCLD types are both available. Charge types are especially excellent for high‐temperature measurements.

Important Specifications When Choosing Accelerometers  

When selecting your accelerometer, please consider the following specifications according to your test application and environment. 

Frequency range
Does the unit selected have sufficient dynamic range for the measurement in question?

Sensitivity
What are the maximum and minimum acceleration levels

Amplitude Linearity
Is the unit linear across the required measurement range?

Temperature range
What is maximum and minimum temperature that the unit will be used at?
