Instead of manipulating reflux to control the delayed and lagged purity measurement, you can manipulate reflux to control a tray temperature. In cascade control, the output of the primary (supervisory ...

Two-wire transmitter technology came about from an agreement among various instrument suppliers in the 1950s to standardize on 4-20 mA current loops as a means of sending a flow, temperature, pressure ...

A real-time temperature control system is designed for microwave heating of a continuous-flow substance. In this system, a magnetron is used as the microwave source, and its output power can be ...

A combined cycle power plant consists of gas turbines, heat recovery steam generators, steam turbines and power generators. The power output of a gas turbine depends on the ambient temperature.

The project is to control the temperature of a heated system using a DC cooling fan. It could be considered as a model for an air conditioning system or some sort of industrial plant cooling system.

Imagine a liquid that flows freely one moment, then stiffens into a near-solid the next, and then can switch back with a simple change in temperature. Researchers at the University of Chicago ...

We report the design, fabrication and characterization of a microelectromechanical systems (MEMS) flow control device for gas chromatography (GC) with the capability of sustaining high-temperature ...
