Versatile tool for bridge measurements for noise and vibration in automotive and defence systems now available.
Brüel & Kjær’s latest version of its data acquisition and analysis system – PULSE 20 – has a host of upgrades, including a versatile bridge measurement tool for industries ranging from aerospace and defence to industrial and automotive.
Primarily used by aerospace and defence engineers to perform dynamic measurements with bridge-type accelerometers and pressure sensors, the LAN-XI module Type 3057 adapts to support virtually any type of transducer, making it ideal for many applications, such as automotive Noise Vibration Harshness (NVH) measurements on brake pedal force or brake caliper pressure.
The module supports strain gauge bridges, contains built in half-bridge and quarter bridge completion – and shunt calibration. It also contains a built in bridge excitation supply which can be configured either as a 0 – 10 V constant voltage source with optional remote sensing or as a 0 – 25 mA constant current source. In addition, the module supports Constant Current Line Drive (CCLD) transducers which are ideal for general vibration measurements such as automotive parts, aircraft and industrial machinery.
Another new tool is the PULSE Reflex Acoustic Camera, which provides a complete system for stationary and non‐stationary measurements. The camera is easy to set up – even for non-experts – providing noise source identification, troubleshooting and leak detection, as well as buzz, squeak and rattle detection in vehicle cabins.
