3205B微型加速度傳感器

概述

The Dytran 3205B is a high performance IEPE accelerometer capable of operating at temperatures up to +347°F (+175°C) and was designed for down-hole drill head vibration monitoring and other low turn-on voltage applications where supply power is limited.

Sensors developed for down-hole vibration monitoring must be able to deliver accurate and reliable data, while simultaneously tolerating harsh conditions. Critical characteristics of these sensors include a miniature design, high temperature operation, and the ability to operate at low power levels. The Dytran model 3205B is ideal for such applications, as it is packaged in a miniature titanium housing with a vertical height of just 0.28-inches (7.1-millimeters) and was specially designed to operate from +4.0 to +4.5 VDC compliance voltage.

The Dytran model 3205B is offered with a 2 mV/g sensitivity and is designed with adhesive mounting capabilities. Weighing just 2 grams, units incorporate a 35-inch integral cable assembly terminating to flying leads.
