Transmitter Unit Measures Vibration And Temperature
SKF offers the new CMPT Copperhead Transmitter Unit (CTU), a digital vibration and temperature measurement, and transmission tool. Working with machinery fault detection systems for fans, pumps, gearboxes, and electric motors, the CMPT CTU can measure temperature and analyze three types of vibration signals to assist users in selecting the appropriate analysis for a preferred application.
The CMPT CTU has special functions for low-speed machinery, with an ability to monitor unbalance and misalignment down to 120 r/minute, and bearing and gearbox condition down to 20 r/minute. Data is transmitted using 4-20mA or 0-10V DC or CAN-bus messages, while the CAN-bus interface enables remote communication with a control system or operator terminal to allow remote configuration and monitoring of the CMPT CTU. This also allows multiple units to be connected by a serial communication cable.
The CMPT CTU can be delivered as a turnkey 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.
The CMPT CTU comes in a 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.
