measurement microphone / prepolarized / 1/2" / random incidence
Bruel and Kjaer
1/2", random incidence
Designed for general random-incidence measurements and for noise measurements in accordance with ANSI standards.
Type 4942-H-041 is designed to resist high-temperatures (up to 125ºC / 257ºF) for general random-incidence measurements and for standardised noise measurements in accordance with ANSI standards. And being prepolarized it can connect to CCLD input conditioning.
THIS MICROPHONE IS A FACTORY-ASSEMBLED COMBINATION OF:
Microphone: Type 4942
Preamplifier: Type 1706
The unit is assembled in a clean-room environment and sealed together, after which it is assigned one single type number and one single serial number. This means that the combined unit has better precision and long-time stability, and is handled as one complete unit.
The unit also contains TEDS, which means that information about the serial number, type and sensitivity is stored within it.
THE BENEFITS OF USING A MICROPHONE-PREAMPLIFIER COMBINATION ARE:
Better stability and precision. Because the unit is assembled in clean-room facilities, there is no contamination.
Ease of use. Your analyzer front-end and software will automatically detect the type number, serial number and sensitivity because of the built-in TEDS technology. There is no need to enter this manually for every channel.
Calibration integration. The TEDS technology means the microphone is automatically detected and identified by your data acquisition software, allowing it to be easily integrated with your calibration database.
