3003B微型三軸加速度

概述

The Dytran 3003B is a high performance triaxial IEPE accelerometer capable of operating at temperatures up to +347°F (+175°C) and was designed for down-hole drill head vibration monitoring.

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 3003B is ideal for such applications, as it is packaged in a miniature titanium housing with a vertical height of just 0.37-inches (9.4-millimeters), is capable of reliable operation at temperatures up to +347°F (+175°C), and was specially designed to operate from +4.0 to +5.5 VDC compliance voltage.

The Dytran model 3003B triaxial accelerometer is offered with a sensitivity of 2 mV/g and 500g range, and is designed with adhesive mounting capabilities. Weighing just 6 grams, units incorporate four permanently attached 22-inch long lead wires.
