The Metrix ST5484E is a self-contained, loop-powered seismic velocity transmitter that incorporates a piezo-electric accelerometer, signal integrator, RMS peak detector, and 4-20 mA signal conditioner into a single, robust package.  The transmitter can be mounted directly on the machine case or bearing housing without need of any intervening signal conditioning equipment.  Its 4-20 mA output signal is compatible with most industrial process control instrumentation such as PLCs, DCSs, and SCADA systems, allowing trending and/or alarming capabilities for a simple, economical vibration monitoring solution.  The transmitter is also available in a 4-wire version where the extra two conductors provide direct access to the raw acceleration signal, facilitating easy connection to portable data collectors and analyzers
