Jul 12, 2012 Able to measure vibration in harsh industrial environments, Type 8347-C piezoelectric charge accelerometer comes in hermetically sealed housing of INCONEL® alloy and withstands temperatures from -321 to +900°F. Shear design lends to thermal stability, and transducer is individually calibrated using random excitation and 1600-line FFT. Profile of 20 mm suits confined spaces in applications such as gas turbines, aircraft engines, turbo pumps, and health and usage monitoring systems.

Data Analysis Software provides test-FEA integration tools.

Brüel & Kjær    Norcross, GA 30071-1588
Mar 28, 2012 Part of PULSE v16.1, PULSE Reflex Modal Analysis software includes interfaces for importing FE models from FEA programs, such as NASTRAN® and ANSYS®. FEA results are useful for test planning as modes can be animated to indicate frequency range of interest, mode density, and critical modes for test. With PULSE Reflex Correlation Analysis package, users can perform complete visual and numerical correlation analysis of 2 modal models, in terms of natural frequencies and mode shapes.

Vechicle Noise Testing Software uses source path contribution technology.

Brüel & Kjær    Norcross, GA 30071-1588
Feb 07, 2012 Intended for PULSE analyzer system, PULSE v16.1 includes Source Path Contribution (SPC) technology that lets testers verify contributions of individual noise sources to exterior receivers. Indoor pass-by with contribution analysis is also included and is further supplemented by Time Insight software, which lets users listen to SPC results, switch paths on and off, listen over certain time or rpm range, compare different sets of results back-to-back, and apply filters.

Handheld Sound Intensity System performs in-field measurements.

Brüel & Kjær    Norcross, GA 30071-1588
Nov 29, 2011 Comprised of sound level meter, sound intensity software, and sound intensity probe, 2270-G can assess power and location of noise sources. Battery-operated, portable system provides on-screen camera pictures of measurement object and displays colored sound power contours over image. Operated by one person, solution uses phase-calibration technique that enables all measurements to be made using one spacer between 2 microphones on sound intensity probe, covering 50 Hz to 10 kHz range.

Noise and Vibration Monitoring Service targets construction sites.

Brüel & Kjær    Norcross, GA 30071-1588
Nov 28, 2011 Offered as subscription-based service, Construction Sentinel facilitates effective compliance monitoring at construction sites by combining noise and ground vibration monitoring. Solution also enables users to identify cause of vibration events by remotely listening to noise on site. Managed from same platform, service alerts users in real-time and automatically compiles and distributes reports that show compliance with legislation.

Data Analysis/Reporting Software helps manage airport noise.

Brüel & Kjær    Norcross, GA 30071-1588
Nov 18, 2011 With task-focused Web browser interface used for mapping, data analysis, and reporting, NoiseDesk helps regional airports grow while maintaining control over noise impact and managing community expectations. Intuitive functionality, without requiring specific expertise with noise monitors and correlated radar data, guides user through workflow of management issues such as track keeping, noise limits, complaint handling, and noise compliance.
