Chapter Four 2010-2015 Global and Chinese Market of Positioner
Three virtual prototypes of (industrial) small scale robotic arc welding cells including above mentioned positioners
having 2 workstations with 1/2/3 NC axes are shown in Fig.
Wolf Robotics discovered that not only was the actual cost of reconfiguring a new robot with existing positioners
was substantially less than building a totally new system but the plan would create value added services such as new robotic technology, new software, new and longer warrantees, and new components.
Because there are four positioners
included alongside the robot and the linear track (resulting far too many external axes for only one controller) it became necessary to assign multiple tasks for commanding all these units.
The second option was to modify the existing systems with new controllers, linked to the old robots and positioners
After part completion, the fixture with the part is unloaded, and a different fixture with a part is loaded on the positioner
Combined with a remote set point adjustment feature using either the 4-20mA signal or through the AS-interface as well as manual actuation and high powered coloured status LEDs, the new valve positioner
provides all the key features required in a modern process control system.
The FDA has never cleared an infant sleep positioner
to prevent or reduce the risk of SIDS.
The Logix 3400MD uses Flowserve ValveSight technology to monitor the status of the valve, actuator and positioner
, and the health of the entire control loop.
The ICoT 5000 Smart Valve Positioner
is an electro-pneumatic servo system that continuously controls the position of a valve based on a 4 to 20 mA input signal or Foundation Fieldbus input signal.
But other components -- such as the power supply, controller, sensing systems, positioner
, safety features, and the mounting base -- are no less critical to the system's efficient operation.
Manual grinding is done on larger castings as they move along a conveyor line in a holding fixture or as they are held stationary in a multiaxis positioner
