The CMSS 420 series are solid-state, loop-powered vibration transmitters. They provide a 4 to 20 mA, output that is proportional to overall vibration in terms of velocity. The series of CMSS 420 continuously monitor machinery health and transmit directly into a PLC or DCS for trending, alarm, and machine shutdown. In addition, the CMSS 420VT provides access to the dynamic transducer output. The buffered output is available for the temporary connection of portable analyzers for detailed machine fault analysis.
