BETWEEN 1990 and 2005, the instrumentation, systems and automation industries were the subject of significant, not to say massive, change. Not only was this change of a technical nature, with significant advances in many product areas, but also this period has been one of consolidation among supplier companies who furnish instruments and control systems. It appears that this consolidation will continue for the foreseeable future.

Identified in this Appendix are more than 200 companies whose name, ownership, or product line changed significantly over the period from 1990 to 2005. This list is not complete, and the authors believe that there are perhaps as many as 50 more companies, most outside North America, whose names have also changed in the same fashion.

This turmoil among suppliers has had a significant effect on the ability of Instrument Engineers to find familiar products, and locate companies for service of existing installed equipment. For example, the Fischer & Porter Company, a well-known name in 1990, had ceased to exist as a marque in 2002. The company, itself, was purchased by Elsag BV, and merged with Bailey Controls to form Bailey-Fischer-Porter. Later, Elsag sold the combined companies to ABB, who elected to drop both trade names in favor of ABB Process Instrumentation. So, an Instrument Engineer whose company installed Fischer & Porter instrumentation or control systems in the early 1990s may now find it impossible to easily find information, manuals, and source spare parts and service for Fischer & Porter systems. Fischer & Porter, as you will see in the table below, is far from the only example of this problem. The Authors therefore provide this information as a public service to the profession.
