Monitoring System For Motors – Web Based

Crompton Greaves offers a web based, low cost Monitoring System. Monitoring the condition of the critical motors is essential for successful operation and to implement condition based maintenance strategy. The low cost web based condition monitoring system (Web based LCMS) acquires vibration, current and speed. The acquired data are stored in the host system and later on transferred to central server through internet. The host system generates brief on-site report. The detailed diagnosis report is generated by the central server and is made accessible for the authorized user through web. Hardware specifications: number of channels (analog) – 6-vibration channels, 2-speed channels, 8-current channels; sampling rate – 25 kS/s; input voltage – ±5 V (vibration, speed), ±20 mA (current); resolution – 24-bit (vibration, speed), 16-bit (current); EMC – yes; CE – yes; expandability – yes; portability – yes; communication – Ethernet; and host computer – 256 MB RAM, Intel Pentium-IV, 1.2 GHz, 40 GB. Software specifications – GUI – available; user admin – available; real time operating system – NI labVIEW; database – Oracle; operating system – RT, Windows (2000, XP, Vista); data storage – central server; MS Office interface – available; and upgradeable – yes. Sensor specifications: accelerometers – make Dytran Instruments Inc, Model 3055B1 (uni axial), 3023A1 (tri-axial); current clamp – make Yokogawa, Model CL255; and tacho-sensor – make Compact Instruments, Model VLS/DA. Applications: web based LCMS focuses especially on industrial fans, mill and pumps – production – critical machinery. Industries in which web based LCMS is currently active are oil, steel, cement, paper and other manufacturing facilities.
