4954-A-023
Free-field microphone designed for high-level and high-frequency measurements with a frequency response of 3 Hz To 80 kHz.
Type 4954-A-011 is designed for high-level and high-frequency measurements. The use of a laser welded stainless steel diaphragm and a stainless steel protection grid, make this microphone capable of withstanding rough environments.
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.
