    摘要： A sensor for monitoring the interior of a sodium-cooled fast breeder reactor comprises a pair of symmetrical magnetic cores (33, 33', 112,112'), a magnetrostrictive or piezoelectric vibrator element (30, 100) bonded to one of the cores, a primary coil (31) and a plurality of secondary coils (32) surrounding the magnetic cores, and a container enclosing the above members. The primary coil (31) applied with an exciting alternating current generates an acoustic signal voltage indicative of sound, if any, originated in the interior of the reactor. The magnetic flux produced by the exciting current is influenced by the temperature and flow velocity of sodium flowing around the sensor, and corresponding voltage signals resulting from the changed magnetic flux are induced in the secondary coils.
