Temperature: The Most Misunderstood Process Variable

Measuring temperature is required in nearly all chemical processes, but engineers often struggle with implementation. Here are suggestions to avoid common pitfalls Measuring temperature in chemical processing applications remains, arguably, the most misunderstood of the four main process variables, which are flow, level, pressure and temperature. Complexity arises from process requirements of an application — such as where and how to locate a sensor — and from the sensing technology itself. we examine one particularly challenging application that incorporates many application-side problems, then dig into sensor and transmitter capabilities and trade-offs.
