As stated in Liberty's Crusade, zerg (which are also psionically sensitive) can only detect a typical ghost from a few yards away. In War-Torn, the zerglings could detect the much more powerful Colin Phash from a long distance (further than the wrangler Randall could).
Gestalt Zero got right up to Muadun before he was noticed, which means zerg are probably the best psionics detector out there. I don't believe the protoss ever mentioned feeling the psi emitters, not even the ones unleashed at Tarsonis (though they did "hear" Kerrigan's cry).
The sources conflict a lot, but I suspect it boils down to power. A typical ghost isn't very powerful, and probably doesn't put out a lot of psionic energy. The protoss might even be picking up "interference" from the psionic power put out by other protoss. A high templar might even be worse at detecting psionics since they put out more than other protoss.
