| 1. A filter rupture detection system comprising:
a light emitter positioned on a first lateral side of a fluid flow and configured to emit light at a predetermined intensity
into the fluid flow downstream from a fluid filter;
a light receiver positioned on a second lateral side of the fluid flow and configured to receive at least a portion of the
emitted light; and
a controller configured to receive a signal from said light receiver corresponding to the intensity of the emitted light,
said controller configured to generate an output signal corresponding to a variation of the intensity of the emitted light,
wherein the output signal is indicative of a rupture of said fluid filter.
