Controllers & Indicators

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.

The making of ceramics is one of the oldest forms of heat-treating known to man. Clay, silica or some type of high purity alumina is shaped, dried, milled and then baked at extremely high temperatures. This high baking process changes the clay material to stone or glass. Depending on the properties that are desired from the end product will determine the material used and the method of firing the work.


Yokogawa first introduced its renowned SUPER CONTROL™ in industrial controllers over a decade ago. This is a fuzzy logic alogrithm that eliminates overshoot from the desired set point and mimics the control expertise of the most experienced operator.


Industria LNG, Verano 2012

Martin te Lintelo, Yokogawa, Países Bajos, discute la necesidad de una mejor automatización, instrumentos de medición y control para hacer frente a la creciente popularidad del 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.

Modbus is a serial communications protocol originally published in 1979 for use with its Programmable Logic Controllers (PLC). It has since become a standard communication protocol and is now a commonly available means of connecting industrial electronic devices.

In this Webinar we will get into the details of how to make Modbus work.

Sign up and learn more about:

  • Modbus configuration: master/slave or client/server
  • Modbus deployment: steps to commissioning a new installation
  • The physical layer of Modbus: wiring
  • Modbus demonstrations

Having knowledge of the different tuning elements and how to adjust them can help you bring these unruly loops under control. If you have the responsibility to keep the processes running at your plant or factory, this webinar will help you better understand the basics of PID control.

In this webinar you will learn:

  • The purpose of each of the PID tuning elements
  • How adjusting the individual PID elements will affect the process
  • General PID profiles for pressure / flow loops
  • General PID profiles for temperature loops
  • An explanation of some supporting parameters like cycle time, manual reset, and anti-reset windup
