1/2" 低频压压力场麦克风
低频麦克风TYPE 4193专为0.07Hz至20kHz频率范围内的次声测量而设计。麦克风采用外部极化，必须与经典前置放大器一起使用。
TYPE 4193
4193型低频麦克风专为 在船舶机房、直升机和风吹建筑物中进行次声测量而构建，由于其极低的截止频率。
与次声适配器UC-0211一起使用时，前置放大器的下限频率为 减小到0.1Hz。
压力场传声器经过优化，在压力场中具有平坦的频率响应，在小型、封闭的耦合器中或靠近坚硬、反射表面时，也能很好地进行测量。麦克风是进行以下操作时的理想选择：

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.
