Title:
【発明の名称】駆動センサー型タンク液面レベルゲージ
Document Type and Number:
Japanese Patent JP3277224
Kind Code:
B2
Abstract:
A level gauge for a tank, of the driven sensor type, comprises essentially: a drum (200) around which is wound a thread on the end of which is suspended a driven level sensor; a reversible servomotor (150) driving the said drum; means (350, 351) for driving the drum in both directions; means for recording drum rotation; means (310, 301, 302) for detecting a variation in the force in the thread, said force being directly related to the relative position of the sensor with respect to the level being measured. According to the invention, the said means for detecting a variation in the force in the thread comprise an element (310) rotatably mounted about a horizontal axis. Its oscillation is limited by damping means (305 to 311) and movement of the element (310) enables the force exerted on the thread to be measured.
