Differential pressure transmitters are extremely versatile instruments fitting a broad range of applications in various process industries. Accuracy is a key performance measure for any process-measuring device, and is an important factor for proper device selection and maintenance. Differential pressure devices are very versatile, but it is not always easy to understand, calculate or compare accuracies between devices. This document is intended to help the reader better understand what manufacturers' accuracy statements mean, what specifications are important for a given application, and how to properly compare various product capabilities.

AVOID TEMPERAURE MEASUREMENT PITFALLS
For more exacting needs, found in many scientific, industrial and commercial uses, the temperature of a process must be measured and controlled definitively. LAN Extensions for Instrumentation (LXI) offer a methodology to perform these exacting measurements in test and control applications. What do you need to know to select the best temperature measurement solution for your application? This paper describes the common pitfalls of precision temperature measurement and what you need to consider before selecting a temperature measurement solution.

TEMPERATURE MEASUREMENT FOR POWER PLANTS
Irrespective of the type of power plant (coal-fired, oil- or gas-based), temperature measurement remains high on the list for operational excellence throughout the plant. Implementation of some of the new technologies results in improved safety and lower installation and maintenance costs. Incorrect measurement information due to temperature effects, non-linearity or stability can result in major equipment getting damaged. Ensuring that instruments that have minimal downtime from a maintenance standpoint, not just devices that have been evaluated to provide safety integrity level service in safety instrumented systems, is crucial for daily operations in a power plant. The paper covers some of the basics of temperature measurement and leads into some of the technical advances that impart a higher degree of safety and reliability to power plant operation.
