Unlike pressure and flow measurement, temperature measurement can be much more complex given what is being measured. Fluids have thermal inertia characteristics which determine their temperature rate of change. In a Process Heating article, Instrumentation Solves Temperature Measurement and Control Problems, Emerson’s Shane Hale describes some of these challenges and how manufacturers and producers are […]
A great source for fundamentals in process automation is the International Society of Automation (ISA)‘s InTech Focus electronic periodical. This series of electronic magazines: …focuses on the fundamentals of essential automation components, such as instrumentation, final control elements, networks, drives, and more. Readers will learn how to choose them, apply them, calibrate them, and optimize […]
When it comes to measuring temperature, there are a multitude of ways to do this. Do-it-yourselfers might use simple RTD or thermocouple sensors right into a microcontroller and display to provide basic temperature readings for their grills and BBQ pits. Or they could buy a ready-made transmitter and software to send the readings to their […]
Emerson’s Jeff Williams presented, Holistic Approach to Steam Temperature Control, at the 2018 Ovation Users’ Group Conference. Jeff opened describing the trend of plants being started and operated more frequently than in the past due to intermittent sources of renewable energy sources on the grid. A key challenge to this mode of operation is to […]
As the contribution of renewable energy sources grow on electrical power grids, so does the cycling its intermittency creates for power producers. This cycling affects steam used to drive the generators. For power stations where the electric generators are steam-driven, this steam is created by coal, nuclear, geothermal, solar thermal, waste incineration and sometimes natural […]
