CMPT CTU system

24/7 fault detection monitoring

With the CMPT CTU on-line monitoring system, you can connect up to 64 distributed CMPT CTU units to one operating terminal (CMPT HMI, fig 1). Each CMPT CTU unit analyzes both vibration and temperature overall levels, 24 hours a day, 7 days a week. The CMPT CTU initiates communication when an alarm occurs. The terminal displays an alarm list, including an alarm events log and operators' acknowledgement of the alarm log.

You can customize the terminal with process views and alarm information for individual projects and customers.
  • Add output relays as an option
  • Connect CMPT HMI to a PLC for data exchange
  • Communicate alarm events by OPC interface, SMS or e-mail

The CMPT CTU is simple to install and little knowledge is demanded of operators after the alarm level is set.

Enhance CTU capability with a lubrication control system

You can use the SKF ST-1240 microprocessor-based control centre (fig 2) for SKF DuoFlex, SKF MonoFlex and SKF ProFlex lubrication systems for controlling two separate lubrication channels or lubrication systems. In addition to lubrication control, the centre can also integrate machinery fault detection functions, and the lubrication control centre can interface with up to ten CMPT CTU units.

Lubrication centre display

The lubrication centre is used for:
  • Displaying temperature and processed vibration signals
  • Setting alarm limits
  • Alarming (visual and relays)
  • Displaying vibration and temperature trends

Each CTU has individual status and setting display pages. The vibration and temperature measurements are saved in the memory of the lubrication centre for trending, where you can display a daily or monthly graph for vibration and temperature.


The CMPT CTU kits are fault detection systems made for general applications, such as fans, pumps, gearboxes and electric motors. The system is based on the fault detection unit (CMPT CTU) and the alarm and display module (CMPT DCL). The standard enclosure is made of polycarbonate with a window for a clear view of components. It also comes with a power supply for CMPT CTU and CMPT DCL units.
