3306A1低溫加速度傳感器

概述

The Dytran 3306A1 is an IEPE accelerometer with continuous operation to -320°F (-196°C), expressly designed to support cryogenic vibration testing requirements.

Offered with a 5 mV/g sensitivity, the design of model 3306A1 incorporates a two-pole low pass filter, which aids in eliminating spurious high frequency data, and a rugged stainless steel construction, along with a 1/4-28 integral mounting stud and an axial mounted, military style 3-pin Bayonet connector. Even at extreme temperatures, the model 3306A1 displays an extremely stable and continuous signal output. Units are hermetically sealed for reliable operation in high humidity and dirty environments. The accelerometer is also electrically isolated via use of an internal Faraday shield for noise immunity.
