SKF CMSS 420VT-1 Loop Powered Vibration Transmitter 0 - 1 in/sec (0 - 25.4 mm/sec)

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 con - tinuously 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 temporary connection of portable analyzers for detailed machine fault analysis. In a addition, the CMCP 420VT-T provides a second 4 to 20 mA output related to temperature.

Simple installation Simply mount the CMSS 420VT into a 1 / 4 -28 or M8 tapped hole in the bearing housing or machine case (NPT mounting adapters are available, part number CMSS 203), connect two wires into a 4 to 20 mA loop, and you are ready to interface with a PLC or DCS. Electrical conduit may be connected directly to the top 3 / 4 in. NPT fitting (NPT mounting adapters are available, part number CMSS 203 ).
