III. Electro Pneumatic Trainer Kit (EPTK) -
Specification:-
The EPTK should consists = of following features
<= span style=3D'mso-list:Ignore'>1)&n= bsp; Suitable cylinders limit switches should be placed = on aluminium plate coupled with a mould plastic guide plate. Base unit to avoid scratching.
<= span style=3D'mso-list:Ignore'>2)&n= bsp; The cylinders and limit switches should be able to = be attached and deattached easily with the work table.
All valves and other components should be mounted on a aluminium cast block fitted with plastic base. It should have an inbuilt pu= sh button for locking and unlocking with work table. The working fluid should = be filtered compressed air. The components and valves of the EPTK should be of actual industrial standard. No tools should be used for connecting the tubes with fittings. All the pneumatic connections should be of push in type fitt= ing for easy connecting and disconnecting.
