The CMCP-420VT is a solid state, loop powered vibration transmitter. CSA and UL Approved for Class I, Div 2 hazardous areas, it provides a 4-20 mA output that is proportional to overall vibration in terms of velocity. The CMCP-420VT continuously monitors machinery health and transmits directly into a PLC or DCS for trending, alarm and machine shutdown. In addition, the CMCP-420VT provides access to the dynamic transducer output. Portable data collector/analyzers can be utilized for detailed machine fault analysis.
Simple Installation:
Simply mount the CMCP-420VT into a tapped hole in the bearing housing or machine case, connect two wires into a 4-20 mA loop, and you are ready to interface into a PLC or DCS. Electrical conduit may be connected directly to the top 3/4" NPT fitting. The CMCP-420VT has a tapped 1/4"-28 UNF hole and has several adaptors to fit almost any application. If the optional LED display is ordered it is shipped loose, and is a simple installation.
