Capacitance-type cylinder displacement meter

摘要

(57) [summary] [purpose] it will be small the influence of the detection output of the invaders from the outside. Interpolate fitted freely reciprocate a rod 5 which forms the other electrode in the cylinder 1 to form a CONSTITUTION] One electrode. Large dielectric of dielectric constant of the barium titanate to the inner peripheral surface of the cylinder 1 1 0 me to cover. The capacitance between the cylinder 1 and the rod 5 is increased, it becomes a more effect on the detection output of the intruder is negligible.
