Wireless Throttling Valve Power Consumption

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

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 …
