Find Your Ideal (Microphone) Type with Brüel & Kjær’s Transducer Catalogue

Naerum, Denmark, September 26, 2019 --( Sound and vibration expert, Brüel & Kjær’s comprehensive transducer catalogue - designed to make it easy for acousticians, engineers and consultants to identify the correct tools - is available as a downloadable document.

Encompassing the company’s full range of transducer solutions and accessories, the catalogue groups instruments by their most important specifications, making it simple for the reader to select the correct tool for their measurement tasks.

Created especially for acoustic and vibration test applications within many industries - including automotive, aerospace, telecoms and construction - the catalogue’s extensive range of transducers includes the latest products, such as the Type 4966 free-field microphone for high-precision acoustic measurements.

The Type 4966 is a ½ inch, prepolarized microphone, built with a press-fitted back plate, to provide improved mechanical accuracy and withstand harsh environments. Optimised for free-field environments, the microphone also provides a flat, free-field response at 0° incidence, making it ideal for use in anechoic chambers or far away from reflective surfaces, such as buildings - and for general electroacoustic measurements, including testing of loudspeakers and microphones.

The transducer section of Brüel & Kjær’s website also offers a mobile application called Transducer Smart Setup, that works in combination with data matrix codes (similar to QR codes™) on some accelerometers, to simplify and automate multi-channel test setups. The data matrix code also provides instant access to specifications and calibration information.

More information about the company’s transducer catalogue and tools can be found on its website:
