Rotork Controls is the home of the flagship IQ intelligent electric actuator range. The IQ range features legendary innovations including Rotork's unique double-sealed enclosure, ‘non-intrusive' infra-red commissioning, data-logging and predictive maintenance capabilities. More recent innovations include the advanced display, Bluetooth® communications interface and absolute encoder.
The IQ functionality and reliability is available for valves of virtually every size and description, including multi-turn (rotary), quarter-turn, isolating and modulating, with watertight and hazardous area approvals to all internationally recognised standards.
Electric actuator ranges also include the AWT for simplified control duties, ROM, ROMpak and Q direct drive actuators for small quarter-turn valves and IEEE qualified NA actuators for the nuclear power industry.
Rotork actuators are compatible with a wide range of communication and process control systems. Rotork's own Pakscan system offers advanced actuator network control similar to network control from Profibus, Foundation Fieldbus, Modbus, DeviceNet and Hart.

40 corrections per second2007-12-06 12:27:37 by iamlucky13
What they mean when they say that, is that the computer reads the input states 40 times per second. Each time it reads the input states, it compares the values to expected values, then uses an algorithm to determine the desired control states. We now have computers with processing power to do it hundreds of thousands of times per second...much much faster than the response times of the systems involved and sometimes faster than any actuators can actually respond.
The algorithms are engineered from known factors like lift, drag, center of gravity, etc. Then some poor schmuck of a test pilot takes the plane up and determines if the engineers got it right or if it needs a little tweaking (hopefully not a lot of tweaking)

Ultimately, when you minimize signals, you improve the overall efficiency and performance of the network.
