STI Loop Powered 4-20mA Vibration Velocity Transmitter

The CMCP420VT is a solid state, loop powered vibration transmitter. It provides a 4-20 mA output that is proportional to overall vibration in terms of velocity. The CMCP420VT continuously monitors machinery health and transmits directly into a PLC or DCS for trending, alarm and machine shutdown. In addition, the CMCP420VT provides access to the dynamic transducer output. Portable data collector/analyzers can be utilized for detailed machine fault analysis.


Alternative to Balmac 191-1 & 191-2
