3311A 超小型加速度傳感器

概述

The Dytran model 3311A is a low profile, high frequency ring shaped IEPE accelerometer with a 50 mV/g sensitivity and an overall weight of just 3.3 grams.

The accelerometer was designed to reliably operate in temperatures up to +320°F (+160°C) and feature a unique sensing element to ensure greater stability over a wider temperature range. Designed in a lightweight laser welded titanium housing, electrical connection for the Dytran model 3311A is achieved via a specially designed coaxial glass-to-metal sealed 5-44 radial connector. The model 3311A also features a thru hole mounting configuration, allowing the sensor to be turned 360° prior to securing for ease of sensor installation. Units are hermetically sealed for reliable operation in high humidity and dirty environments as well as base isolated, to avoid EMI/ground loop interference.
