1/2“低频压力场传声器
低频传声器Type 4193专为在0.07 Hz至20 kHz的频率范围内进行次声测量而设计。该传声器为外部极化，必须与经典的前置放大器一起使用。
4193 系列
4193型低频传声器专为在船舶发动机舱、直升机和风吹建筑物中进行次声测量而设计，因为其极低的截止频率。
当与次声适配器 UC-0211 一起使用时，放大器的下限频率为降至 0.1 Hz。
压力场传声器经过优化，在压力场中具有平坦的频率响应，非常适合在小型封闭耦合腔中或靠近硬质反射表面进行测量。在以下情况下，传声器是理想的选择：

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.
