SKF’s CMPT Copperhead Transmitter Unit (CTU) is a new 24/7 digital vibration and temperature measurement and transmission tool that can work with machinery fault detection systems for fans, pumps, gearboxes and electric motors.
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.
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.
