QUESTION
For the extension of the cylinder shown below, a force of F = 300 N is needed. If the frictional force is 10 % of F, how high must the applied air pressure pe be to move the slide?
-pe = 2.75 bar
-pe = 4.5 bar
-pe = 5.5 bar
-pe = 6.5 bar
Answer:
-pe = 2.75 bar
QUESTION
Which statements about the component shown below are correct? Two Answers are correct
-The air pressure at X acts on a cylinder surface. If the force exerted exceeds the spring force of the return spring, the piston moves and operates the contact set.
-An electronic pressure sensor with digital output signal is shown. Instead of actuating mechanical contacts, the output is switched electronically.
-Y is a knob for adjusting the spring force of the return spring.
-When the piston moves to operate the contact set the connection between 2 and 4 is closed.
-Y is a pushbutton to check the functionality of the pressure switch.
Answer:
-The air pressure at X acts on a cylinder surface. If the force exerted exceeds the spring force of the return spring, the piston moves and operates the contact set.
-Y is a knob for adjusting the spring force of the return spring.
