Rokade Rototechniks

Locating the vibration sensors as indicated in the schematic will be most sensitive and effective in detecting the above faults listed. The sensor orientations are summarised as follows:

• HORIZONTAL on two motor bearings (A & B) and two fan bearings (C&D). B&C ideally recommended
• VERTICAL on motor & fan drive end bearings (B&C).
• AXIAL on motor & fan drive end bearings (B&C). B or C is recommended

ROKADE PHANTOM is a Predictive Maintenance system for Online Vibration Monitoring that provides alerts, advanced analysis, and reporting – helping users to prevent failures.

It captures the parameters such as Vibration (Triaxial), Temperature, Current, RPM and speed into a single diagnosis system. 

In addition, our sensors have a battery life that lasts between 3 to 6 years and are very easy to install.

The eMT350 Loop Powered Vibration Transmitter (Single Channel) is most suited for general Balance of Plant Rotating Machinery whereby the vibration signals are often converted to 4-20mA DC and interfaced to the DCS loop power system and trended to monitor machine defect progression. The overall vibration is sufficient enough to include basic machine faults. The PLC or the DCS are configured for the full scale range and compare vibration level with predefined Alarm and Trip levels.However, for analysis purposes TWF AC raw signal is provided in the front panel on a BNC connector, as an option.The unit can accept input from most sensors and unlike Loop Powered sensors, eMT350 and its sensor can be calibrated periodically meeting ISO9000 requirement.For field applications, the IP65 or IP66 enclosure are available, as required, to accommodate 1, 2, 4 or 8 number of eMT350’s.The re-transmission analogue signal can be trended in DCS/PLC to monitor defect progression and plan maintenance considering production schedule and fix the problem before catastrophic failure.

Features:

• Unbalance
• Misalignment
• Bad bearings
• Mechanical looseness
• Aerodynamic forces
