美国dytran 3049D 高温型加速度传感器

概述

The Dytran model 3049D is a rugged high temperature charge mode accelerometer, designed to reliably operate in temperatures up to +350°F (+177°C). Featuring a lightweight titanium housing and a sensitivity of 5.8 pC/g, the base of the model 3049D is electrically isolated to avoid EMI/ground loop interference. Units are also hermetically sealed for use in demanding environments.

This sensor is part of Dytran's 3049D piezoelectric accelerometer series, which differ only in terms of their mounting configuration. The model 3049D features a 10-32 mounting stud, while its counterpart, the model 3049D1, is offered with adhesive mounting capabilities.
