Novel nuclear level gauging device

The utility model discloses a novel nuclear level gauging device, it includes the feed bin, and feed bin inner wall outside -in is equipped with insulating layer and wearing layer in proper order, andit still includes measuring unit, and measuring unit includes emission module and receiving module in the levels in feed bin, emission module is including measuring the sleeve pipe, take out lock pinand radiation source, fixed the locating in the feed bin of measurement sleeve pipe level. The utility model discloses a drawback that exists to traditional measurement mode and the miniaturization gone on, the facilityization improvement, the feed bin is placed in with the radiation source in to the lock pin structure of taking out through small -size lightweight design, the problem of feed binouter wall to nuclear ray separation decay has been avoided, can reduce the energy level in the nuclear source of selecting, and then use the low radiation that exempted by the country to examine source na22 as the radiation so
