3243A防潮三轴加速度传感器

概述

The Dytran 3243A is a low profile, moisture resistant triaxial IEPE accelerometer with an overall height of 0.30 inches (7.6 millimeters) and weighing just 2.5 grams.

Featuring titanium construction, a 10 mV/g sensitivity and adhesive mounting, the model 3243A incorporates a 2-meter integral cable with a splash-proof boot at the point of sensor and cable connection. The hermetically sealed cable-to-accelerometer boot seal makes it possible for the sensor to be temporarily submerged during testing. Units are case isolated to avoid EMI/ground loop interference.
