3085C 高溫型加速度傳感器

概述

The Dytran model 3085C is a single axis high temperature differential output accelerometer with 10 pC/g sensitivity, designed to measure surface vibration at temperatures up to +600°F (+316°C). This piezoelectric charge mode accelerometer features a case isolated design with a hermetically sealed stainless steel housing and incorporates a ceramic crystal operating in compression mode.

Model 3085C offers an industry standard tri-bolt mounting flange and a transverse mounted glass-to-metal sealed 2-pin electrical connector.
