Small Size And High Temperature Quartz Accelerometer
Introduction
ER-QA-03F is a small size accelerometer which has high reliability, mainly used in oil well logging. Output current and received force into a linear output, user can according to calculate to choose reasonable sampling resistance, to reaching the highest accuracy output. It can also be used for static testing and dynamically testing, it is a standard vibration sensor.
