I am an engineer and have worked in the field of process
control for over 25 years. Until mid 1994 I worked at Taylor Instrument Company, now part
of ABB Industrial Systems. Currently I am owner of Process Control
Solutions, which provides consulting services to users of DCSs and other control
systems in the Pharmaceutical, Chemical, Power, Pulp and Paper, Textile, and other
industries. I am a senior member of ISA and also a member of AIChE and TAPPI. I live in
Rochester NY Due to my experience with the ABB Mod 300 and Advant systems much of my work is related to those systems. See Details |
