7521A1 DC加速度传感器

概述

The Dytran 7521A1 is a single axis DC resp*e accelerometer designed to offer a simple and cost effective solution for low level, low frequency vibration measurements. Tailored for zero-to-medium frequency applicati*, the Dytran model 7521A1 has a low end frequency resp*e of 0 Hz and an upper frequency range of 1,500 Hz, with a total weight of just 3.7 grams.

Available with a 2g range, units feature a lightweight housing, integral 79-inch cable and are mounted via two M2 screws (supplied). The Dytran model 7521A1 is supplied ready-to-operate and requires only a regulated 5V power supply.
