The CMPT CTU measures temperature and can measure and analyze three types of vibration signals - SKF’s acceleration enveloping, acceleration or velocity - while enabling the user to select the appropriate analysis for the preferred application.
The unit also has special functions for low speed machinery, with an ability to monitor unbalance and misalignment down to 120 r/min, and bearing and gearbox condition down to 20 r/min.
The CMPT CTU transmits data using 4-20mA or 0-10V DC or CAN-bus messages. The CAN-bus interface enables remote communication with a control system or operator terminal to allow remote configuration and monitoring of the CMPT CTU. The CAN-bus also allows multiple CMPT CTUs to be connected by a serial communication cable, which significantly reduces wiring and enhances the CMPT CTU’s capabilities.
The CMPT CTU can be delivered as a turn-key solution with an operating terminal (CMPT HMI) for alarm display, logging and management. Up to 64 distributed CMPT CTUs can be connected to one operating terminal. The CMPT HMI features a user-friendly 3.5-inch or 5.7-inch touch screen and is delivered with a pre-programmed alarm list that can be downloaded to a USB memory flash drive. The terminal can be customized with operator-specific views, multiple languages and various output options.
“SKF’s Copperhead technology provides machine operators with an easy-to-use, highly adaptable and reliable process for machine fault detection,” says Andreas Nyström, sales engineer, SKF Condition Monitoring Center. “The enhanced productivity, reduced downtime and maintenance, and improved machine reliability that results can bring significant benefits to the bottom line.”
In addition, the SKF ST-1240 lubrication control system can be interfaced with up to 10 CMPT CTU units to provide ongoing monitoring of lubrication system functionality and detecting faults. Alarm indication is provided by lamp and system relay.
The CMPT CTU is available in an easy-to-order, flexible kit that contains an SKF CMPT CTU, an alarm and display module (CMPT DCL) and a polycarbonate enclosure with a window for a clear view of components. Power supplies, sensor input signals and processed output signals are connected to terminals at the bottom of the enclosure for easy access. All parts are DIN-rail mounted.
