At booth 9016, where Brüel & Kjær’s was exhibiting, visitors were able to learn more about the latest version of its data acquisition and analysis system, PULSE 20, which has a host of upgrades, including a versatile bridge measurement tool. Used 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 NVH measurements on brake pedal force or brake caliber 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 0-10V constant voltage source with optional remote sensing or as a 0-25mA constant-current source. In addition, the module supports constant-current line drive transducers, which are ideal for general vibration measurements such as automotive parts.
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.
