Yokogawa Electric Corporation announces that it has enhanced its YS1000 series single loop controllers, and will be releasing them on June 13 in all markets except Japan. The controllers feature a new thin film transistor (TFT) LCD with improved display characteristics and a design that facilitates easy maintenance.
Single loop controllers are used in a wide variety of industrial facilities such as power plants, oil refineries, petrochemical plants, chemical plants, and iron and steel plants. These controllers receive temperature, flow rate, pressure, and other types of measurement readings from sensors and send corresponding instructions to control elements such as valves in order to maintain these values within a desired range. Each control loop* has its own controller. Single loop controllers are widely used in industry today to control small plant facilities and serve as back-ups to distributed control systems.
Yokogawa released its first analog controllers in the 1960s, and went digital in the 1980s with the release of the microprocessor-equipped YS80 series digital single loop controllers. The company continued to improve its products and followed up by releasing the YS100 series in 1991 and the YS1000 series in 2007. Today, for such reasons as the decline in the number of skilled engineers in the workforce, many of our customers have a need for controllers that are easy to use and maintain. To meet such needs, Yokogawa has improved its YS1000 series controllers.
