Cameron's Compression Systems Group: CCVM Vibration Monitor

Overview:

The CCVM-16 Compressor Monitoring System from Cameron gives you a complete, cost-effective monitoring package for your critical integrally geared centrifugal compressors. Virtually everything you need is included, which means less time planning for and installing the system, and more time available for you to manage your business.
What problems will the CCVM-16 detect?

Motor vibration due to misalignment or unbalance
Structural instabilities
Excessive bull gear vibration
Excessive compressor pinion vibration
Pinion/bull gear teeth damage

What outputs will the CCVM-16 provide?

Machinery condition data to a PLC/DCS
Alert, Danger, OK indication
Relay outputs
Buffered output via front panel
CompactFlashTM Memory of condition data

The CCVM-16 is offered in configurations of 4, 8, or 12 channels to monitor vibration, thrust, and temperature. The unit accepts inputs from most new or existing sensors including accelerometers, velocity sensors, and eddy-current proximity probes, RTDs and thermocouples. Each channel can be configured to display vibration expressed as acceleration, velocity, or displacement, or be configured for monitoring thrust or temperature.

A bright, color LCD touchscreen provides access to programming functions such as alarm setpoints, sensor setup, and relay configuration, in addition to a unique color-coded relay mapping function. This advanced relay feature provides three individual sets of OK, Alert, and Danger relay contacts that allow the channels to be grouped together in any combination, making the CCVM-16 ideal for protecting multiple machines or alarming only on certain machine conditions. Recorder outputs (4-20mA or 1-5VDC) for each channel also are standard. The monitor is equipped with a unique CompactFlash™ memory feature that allows users to store overall vibration levels, alarm status, and bias or gap voltage, along with a time-date stamp, to a CompactFlash™ card and easily upload the data to Microsoft Excel or most predictive maintenance (PdM) software packages for trending and display.

The CCVM-16 also offers features such as a programmable start-up delay to inhibit or multiply alarm setpoints when a machine is started, and a machinery specification file accessible via the front panel of the monitor to store reference data such as compressor model numbers, serial numbers, and contact information.

By providing early indication of increased vibration levels, the CCVM-16 helps you identify common compressor problems before they cause costly catastrophic damage. Many of the most common problems can be corrected, and an unplanned outage avoided, if they are detected early.
A typical CCVM-16 system configuration for a 4-stage integrally geared compressor is depicted on the following page. A brief questionnaire is also included to allow us to configure a system specifically for your compressor. Just fill in the blanks and forward the sheet to us and we will generate a quote tailored to your needs.
While the CCVM-16 is ideally suited for monitoring integrally geared compressors the system can, of course, be designed to meet a variety of your common monitoring needs for other types of machinery. Please contact a Cameron representative for assistance in configuring a system for machinery not covered here, or for more information on our other products.
