Brüel & Kjær has launched the world’s first preamplifier and preamplifier/microphone combinations to withstand temperatures up to 125 degrees. The high-temperature 1706 Microphone Preamplifier enables engineers to make acoustical measurements, nearer to the sound or noise source of hot devices, such as engines and gas turbines.

By getting closer to the source, it’s much simpler for the engineer to identify and deal with any potential issues, making it ideal for testing applications including gas turbine auxiliary equipment, environmental stress screening, automotive engine and exhaust systems.

1706 can also be used with a Smart Transducer interface, which is in accordance with the IEEE 1451.4 standard. The ability to store and recall Transducer Electronic Data Sheet (TEDS) data dramatically reduces test setup time, which helps reduce cost in most measurement situations.

The new High Temperature Preamplifier 1706 is also available to use in combination with a Free-field or a Diffuse-field ½ Microphone, where the data of the combination of the preamplifier and the microphone are stored in TEDS.

Detailed individual calibration information and compensation for accessories - such as wind screens - are supplied on a CD with the microphone and preamplifiers, which allows very accurate measurements.

The Microphone and Preamplifier combinations available are a ½ Free-field Microphone 4189-H-041, with 6 Hz to 20 kHz, prepolarized and includes the 1706 with TEDS.

There is also a 4942-H-042 ½ Diffuse-field Microphone, with 6.3 Hz to 16 kHz, prepolarized and include the 1706 with TEDS.
