For many organizations, vibration analysis is the conrnerstone of their predictive maintenance (PdM) efforts and reliability process. Of all PdM technologies, vibration analysis often provides the greatest return on investment because it can be the most comprehensive and most precise. The technology is ideal for many electro-mechanical assets, especially ones experiencing varying operating conditions. Used infrequently, the technology effectively identifies actual and potential problems. When used routinely as part of a well-designed reliability process using PdM, vibration analysis predicts major asset problems up to one year in advance and provides many times the return on investment of a program using vibration analysis intermittently.

Often, the most complex equipment in an operation is also the most mission critical (e.g. variable load, variable speed mills). Most service providers are competent enough to analyze the simple, constant load, constant speed equipment. However, the list narrows when organizations require a complete provider for analyzing the complex equipment within an operation.

Proprietary technology developed iteratively over the past 25+ years enables ITR analysts to perform advanced analysis techniques that most other companies cannot or do not perform because they are too complex or time consuming. ITR is committed to ensuring it will always be the most capable variable load, variable speed analysis company in the world. By designing processes to handle the most complex analysis, ITR partners are ensured thier PdM capabilities are the best possible.

Some other differences worth considering:

• ITR analysts are former maintenance managers or maintenance professionals
• Average analyst experience analyzing with ITR: 15+ years
• Database of over 40,000 unique machinery across all major industries
• Over 4 million bearings analyzed since 1990 using no screening techniques
