Fiber optic microphone for indoor as well as outdoor applications for detecting acoustic in a wide frequency range. Ideal for use in industrial plants and in large machines. The housing is 100% from industrial plastic and thus can also be used in the electromagnetic environment. A micro-membrane detects the pressure differences and an optical head, the differences of a light signal (Density Modulation) to be transferred. Over the fiber optic link which can be up to 400m long, the light signal to the electronic evaluation system is transmitted. The principle is very simple and therefore very robust.
