Our complete product line supports every type of control application. Models with Active Color PV display and Ethernet connectivity are now available.

  • Single Loop Controllers

    Single loop 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.

  • Temperature Controllers

    UTAdvanced temperature controllers and digital indicating controllers employ an easy-to-read, 14-segment large color LCD display, along with navigation keys, thus greatly increasing the monitoring and operating capabilities.

LNG Industry, Summer 2012

Martin te Lintelo, Yokogawa, The Netherlands, discusses the need for better automation, measurement and control instruments to cope with the rising popularity of LNG.


Oil producers looking past today's difficult world markets understand development of new sources will bring a growing list of challenges. An ever-increasing amount of oil and natural gas is being produced by techniques once considered unconventional: tar and extraction, fracking, and deep water offshore drilling. As the costs of these extraction methods have gone down, the range of economically recoverable deposits has increased. When crude oil markets return to more normal levels, these difficult fields, including deep water offshore oil and gas, will become increasingly important.
