Process Control Using Wireless Sensors and Actuators

Conference

Over the last 10 years I have worked with a number of technologists from the process industry on various aspects of control using wireless field devices. Much of this work is summarized in the book Wireless Control Foundation – Continuous and Discrete Control for the Process Industry. Recently Mark Nixon (Emerson) and Willy Wojsznis (Emerson), …

Control Classes – Dubai

Emerson Employees that Attended the Dubai Training Class

In late November, 2014 I traveled to Dubai to teach the Control Loop Foundation class. This class is based on the book Control Loop Foundation – Batch and Continuous Processes and is a standard class offered by Emerson’s education department. In this class the students used the book’s web site to perform the workshops that …

Wireless Throttling Valve Power Consumption

Control to Minimize Changes in Target Valve Position

Something that all manufactures of wireless throttling valves must be concerned with in their design is battery power consumption. In a control application using a wireless throttling valve much of the power available to the actuator is used to track changes in target valve position. To minimize battery power consumption, the number of changes made …

Utilizing Wireless Throttling Valves in Control

Rev_PID vs PIDPlus in Control Using Wireless Valve

Over the last five years a wide variety of WirelessHART transmitters have been introduced by the major manufacturers of field devices. The PIDPlus enables closed loop control using the slower update rate provided by a wireless transmitter. The broad acceptance of wireless transmitters has generated an interest in the application of wireless throttling valves in …

WirelessHART – Monitoring and Control of On-Off Valves

TopWorx_4310

A number of WirelessHART devices have been introduced over the last few years to monitor the status of on/off valves. For example, the TopWorx 4310 WirelessHART Valve Position Monitor can be used detect linear and rotary movement using non-contact technology with limit switch feedback. Such devices provide a low cost way to monitor the position …
