Yokogawa Corp. of America will move its Systems Division Headquarters from Atlanta, Georgia to Houston, Texas in order to focus on its core hydrocarbon markets such as oil, gas, petrochemical and chemicals. The North American headquarters will remain in Atlanta. The core industrial automation, test and measurement, and control product lines, including its Manufacturing Division, will remain in place. As a result of Yokogawa's divestiture in its refrigerant detection product line in February 2002, they will sell the smaller of its two Atlanta manufacturing facilities.
