I have used them, not build them.

The sensor of a PPM is a torroidal coil (in fact there are three at 120deg in a marine type) immersed in a proton rich fluid (filtered kerosene). The coil is fed with a polarising dc current (about 8Amps)for some time. This polarisation current aligns the protons in the fluid, in one direction.

The sudden collapse of the magnetic field, when/after the current is stopped, causes the protons to precess.

The precessing protons induce signal in the coil. Normally same coil is used for both purposes. A preamp and tuned circuit is used to amplify the signal.

The diagram i have is on big blue prints.
