Figure 1-1: CMPT CTU (Copperhead Transmitter Unit)
This instruction manual provides detailed wiring connection and configuration
information for the CMPT CTU (Copperhead Transmitter Unit) vibration and
temperature transmitter. The CMPT CTU is configured by SKF when it is part of an
assembled CMPT enclosure. The CMPT CTU must otherwise be properly installed and
configured by the user. This instruction manual provides the user with information on
how to properly install and configure the CTU and change the default configuration
settings.
Please read this instruction manual and the cautionary notes thoroughly.
The SKF CTU is a digital vibration and temperature transmitter. It can be used as a part
of a machinery fault detection system. The CTU performs three types of vibration signal
process analysis – SKF Acceleration Enveloping (gE), Acceleration (g), or Velocity (mm/s
or inch/s). The type of vibration analysis is user configurable. The CTU has analog
output signals proportional to processed vibration analysis and temperature for
connection to automation systems and SKF CMPT DCL monitors. The CTU is user
configurable to process vibration signals from the SKF CMPT family of sensors or other
industrial accelerometers.
Acceleration Enveloping vibration analysis is used to identify repetitive impact type
vibrations generated by machinery faults due to loose components, gear faults, lack of
lubrication and rolling bearing faults.
Acceleration vibration analysis is used to monitor overall machinery and structural
vibration, including machinery having journal bearings. It can also be used to measure
the overall operation of vibrating screens and other vibrating equipment.
Velocity vibration analysis is used to identify overall machinery vibration levels such as
looseness and unbalance, including machinery support by journal bearings.
The CMPT CTU has unique features to monitor both high speed and low speed
machinery (n <40 r/min).
