CSI A0643TX Triaxial Accelerometer with Integral Magnet

Overview

The CSI A0643TX is a rugged, high-performance triaxial accelerometer built for Emerson’s AMS 2140 and CSI 2130 analyzers. It uses a patented integral magnet for quick attachment to flat or curved surfaces. This eliminates the need for mounting pads or brackets. With simultaneous horizontal, vertical, and axial vibration measurement, it greatly reduces data collection time during route-based monitoring.
