3054B加速度傳感器

概述

The Dytran model 3054B is a unique, miniature biaxial accelerometer designed to be inserted up to 40 feet into 0.319 inches-diameter heat transfer tubes for the purpose of measuring transverse acceleration of the tube.  The Dytran model 3054B uses 8 beryllium copper springs attached to the outside of the sensor body, to guide the unit into the tube and allow for slight variations in tube inside diameter and for some buildup of foreign materials inside the tube. Biaxial in design, model 3054B incorporates two quartz sensing elements operating in shear mode. Units are internally isolated from the sensor case and are enclosed by a faraday shield for electrostatic noise immunity. Alternate spring sizes available (up to .935 inches) to accomodate larger tube diameters; contact Dytran for details.
