Rosemount Analytical PowerVUE 4×5 Power Positioner
The Rosemount Analytical PowerVUE 4×5 Power Positioner convert the linear motion from a pneumatic piston into an 80° rotation of a drive arm. With few moving parts, the pneumatic power positioner remains the simplest, most reliable and most cost-effective method of actuation. Torque ranges are offered from 400 ft-lbs to 4,600 ft.-lbs.
These instruments use two-wire loop power for low-cost replacement of existing instruments. The two-wire design avoids cost of separate power and signal wiring. Self-diagnostic capabilities allow you to check fan/damper actuator performance in place. You can compare the present signature (load, friction, etc.) against stored signatures to discover performance changes before they cause problems.
Applications for the PowerVUE 4×5 Power Positioner include:
Utilities
Steel mills
Refineries
Pulp and paper
Waste water (aeration blowers)
