introduction

INNOVATIVE SOLUTIONS

At Brüel & Kjær we have always set standards – from the first range of measurement microphones to the first multi-analyzer, the first real-time acoustic holography system and the first battery-powered sound intensity analyzer. the technical developments have been driven by close collaboration with our customers. we focus on our customers' needs to supply the whole measurement chain – from a single transducer to complete turnkey systems. we maintain alliances with suppliers that enable us to deliver newer and more efficient ways for our customers to improve their products' quality and stay competitive. technology has no limits – if our customers can imagine it then we will strive to develop it.

TOP QUALITy

in all aspects of sound and vibration there are challenges to be met. For example, ensuring that the car, bus or train for your daily commute can withstand the mechanical shocks it will experience demands measurements of great accuracy and precision. this requires instruments with the performance and quality to match. All our products are thoroughly tested, often in the harshest environmental conditions. extremely high standards are met in all aspects of product and service provision, as reflected in our status as an iSo 9001 certified company. thanks to their reliability, quality and robustness, our products usually come with a service period of at least 5 years after the end of production. Not only customer demands need to be met – the same applies to legislation. this often means documented results that are traceable to established references, such as a national calibration laboratory. the Brüel & Kjær service centers offer all the support required.

TRAINING COURSES

educating and training customers is part of the Brüel & Kjær tradition. we focus on educating and equipping the course partici-pants with the necessary sound and vibration knowledge and skills. our global educational programme offers modular courses and training that cover theory, applications and instrumentation.

we offer:

training courses at locations near the customer

experienced instructors from our company

Latest high-quality training materials

For larger numbers of participants we offer in-house courses

Sound LeveL MeterS in tHe WireLess WorLd

in december 1901 Marconi transmitted a radio signal from the west coast of england across the Atlantic to St. John’s in Newfoundland, a distance of 2,100 miles. in modern times, wireless communication has replaced cable connections little by little and has become a key factor in our digital age. in July 2009 the development of a web browser functionality enhanced the type 2250 family of hand-held analyzers with wireless communica-tion capability. this innovative feature allows remote access to the instrument via mobile phone, PdA, Smart

phone or Pc with internet connection and can be used to view noise levels in real-time, select settings and transfer results.

types 2250 Light, 2250 or 2270 just need an active wLAN connection to the internet via 3G, GPrS, edGe or GPrS router. the user enters the specific iP address or the location in the browser address field, and the analyzer's keypad and display are shown on the computer screen.
