$795,00
OVERVIEW
Description
The SA12 is a cost-effective, MEMS-based seismic-grade accelerometer designed for strong-motion monitoring, vibration analysis, and structural health monitoring (SHM). Its compact and lightweight design, coupled with proven robustness and shock resistance, makes it an ideal choice for long-term deployment in various structural and geotechnical applications.
Featuring an analog true differential output, the SA12 supports long cable runs and is compatible with a wide range of data acquisition systems (DAQs). It is available with cable or connector output options and includes an optional mounting plate for flexible installation.
