16 Oil hydraulic and pneumatic services in a control engineering laboratory

In planning a laboratory to cover the whole field of control, provision must be made for the oil hydraulic systems which are now such a common feature of the industrial scene, and the pneumatic systems associated with process control and servomechanisms. Assuming that the laboratory will include experimental rigs of this nature, the decision must be made as to how these rigs are to be serviced with their oil or air supply. After visiting a number of control laboratories, certain conclusions were reached with regard to this servicing and these have been put into effect in a new laboratory in this Department.
