| 摘要 |
A flexible scintillation-type level detector ( 10 ), in which the scintillator ( 18 ) is made from a flexible tube ( 12 ) substantially filled with a liquid scintillating material ( 16 ) to provide flexibility in at least two, and preferably three, dimensions. At least one end ( 32 ) is aligned for operable connection to a photodetector ( 14, 20 ). Outer surfaces of the flexible tube ( 12 ) may be covered with an inwardly-facing light reflective material ( 30 ) and/or light-excluding material or flexible armored casing ( 22 ). The scintillator ( 18 ) may include a variable-volume expansion chamber ( 110, 152, 176 ) to compensate for thermal expansion and contraction of the liquid scintillator material ( 16 ).
