Material of Construction :
The Power cylinder is a standard pneumatic cylinder whose stroke positioning is regulated by pneumatic/electro-pneumatic feed back signal. The stroke positioning is made by altering electro pneumatic control signal value (4 mA for zero stroke and 20 mA for full stroke). In between stroke is proportional to the band width of 16mA. Similarly in Pneumatic control positioning the signal of 0.2 bar for Zero stroke and 1 bar for full stroke
The Positioner and the Link mechanism are fitted on the top of the cylinder with a rigid bracket. The link mechanism is connected to the piston rod. The feed back cam moves along with the piston rod and provides the feedback signal to the positioner to position the cylinder in line with the control signal
