ACELERÓMETROS

Los acelerómetros son sensores que utilizan un sistema formado por una masa y un resorte para generar una fuerza proporcional a una vibración. Se emplean en numerosas aplicaciones de ensayo e investigación. Brüel & Kjær ofrece en su catálogo acelerómetros de carga piezoeléctricos y acelerómetros CCLD con tecnología ICP©, DeltaTron™ y TEDS. Nuestros acelerómetros son enormemente adaptables y se encuentran disponibles en versiones monoaxiales y triaxiales. Para cualquier consulta, póngase en contacto con nuestros ingenieros de ventas, que le ayudarán a seleccionar el mejor acelerómetro para su aplicación.

DISEÑO INNOVADOR DE ACELERÓMETROS

En 1943, Per V. Brüel, uno de los fundadores de la empresa, desarrolló el primer acelerómetro piezoeléctrico comercial del mundo a partir de cristales de sal de La Rochelle (tartrato mixto de potasio y sodio).

TECNOLOGÍA DE ACELERÓMETROS

En la actualidad, seguimos a la vanguardia de la tecnología de transductores. Los diseños piezoeléctricos DeltaShear, OrthoShear y ThetaShear, en los que se basan la mayoría de los acelerómetros actuales, son inventos de Brüel & Kjær.

Accelerometer Types

Brüel & Kjær Accelerometer Types

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.

 

Charge accelerometer

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 Accelerometer

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 Accelerometer

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 Accelerometer Specifications 

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

Highlighted specifications to consider:

  • 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?
