The Tricon is a fault-tolerant controller based on a Triple-Modular Redundant (TMR) architecture. What is Fault-Tolerant Control? A fault-tolerant control system identifies and compensates for failed control system elements and allows repair while continuing an assigned task without process interruption.

There are many ways to measure temperature in a process. Sensors, such as thermocouples, RTDs and infrared thermometers are the most common temperature sensors utilized today. A noncontact infrared thermometer has the advantage of being able to measure the product
This small guide gives all you need to select a Pressure Gauge. 1. ACCURACY For a mechanical pressure gauge, accuracy is defined as a percentage of the full-scale range. While requirements differ from one industry to another, the following are
Turbine meters have been used for the custody transfer of refined petroleum products and light crude oils for over 50 years. When correctly applied, they offer high accuracy and long service life over a wide range of products and operating
Contemporary Controls (2012) The ABC of Managed Switches
To minimize controllable losses tied to feedwater heater performance by gaining additional insight into the basic feedwater heater and power cycle operations; associated performance indicators and the positive or negative impact of level control on overall plant efficiency as related
Instrumented safety systems are not new. It has long been the practice to fit protective systems to industrial process plant where there is a potential threat to life or the environment should something go wrong. These systems are independent of
In this age of heightened quality awareness and ISO 9000 it is more important than ever before that all physical quantity measurements which are part of an industrial process are accurate and reliable. Flowmeters are no exception. When in use,
The most sophisticated industrial equipment will not be very useful unless it is calibrated. Through calibration, adjustments made to a piece of equipment ensure that it performs as expected—that it can be relied on to deliver predictable, accurate results that
FOXBORO (1961) ORIFICE PLATES, FLANGES AND CONNECTIONS
This document provides a guideline for choosing and installing Rosemount™ Process radar devices in stilling wells and bypass chambers. Even though process radars generally provide robust operation installed in still pipes, all process radars regardless of make or type are
Free-space radar transmitters for level measurement typically use 6, 26 and 80 GHz frequencies. Recently, there has been a lot of hype concerning high frequency radar transmitters, where some manufacturers claim: the higher the frequency the better the performance.
