METRIX ST5484E-151-132-00 Seismic Velocity 4-20mA Transmitter

Overview

The ST5484E-151-132-00 is a seismic velocity 4-20mA transmitter developed by Metrix. It integrates a piezoelectric accelerometer, signal integrator, and RMS peak detector into a single rugged unit. You can mount it directly on machinery for real-time vibration monitoring. Moreover, it removes the need for external signal conditioning equipment, simplifying installation. The transmitter suits harsh industrial environments and hazardous areas due to its robust design and certifications.
