HIGH-LEVEL SOUND PRESSURE MICROPHONE, EXT. POLARIZED
High Sound Pressure Microphone Type 4941 is designed for extremely high-level measurements such as gunshot, fireworks and rockets over the frequnency range of 4Hz to 20 kHz.
TYPE 4941
The robust construction of this pressure-field microphone allows it to sustain burst pressure up to 201 dB without damage. Being externally polarized, Type 4941 must be used with a classical preamplifier.

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.
