When using a rod type float switch, how is the amount float movement required to open or close the contacts adjusted?

Expert Solution & Answer
Check Mark
To determine

The method of adjusting the amount of float movement that requires to open or close the contacts.

Explanation of Solution

Float switches are the switches that control the operation of a pump with respect to the level of liquid present in the storage tank or sump. In rod type float switches, a float is connected to a rod that moves up or down according to the level of liquid present in a tank or sump, thereby opening or closing the contacts of a float switch.

Before employing a float switch, the amount of movement of float that is required to open or close the contacts of a float switch should be defined and configured. The configuration of float movement is achieved by adjusting the stops provided on the rod.

Thus, the amount of float movement that is required to open or close the contacts is equal to the distance between the stops of a float rod. By adjusting the stops of a float rod, one can vary the amount of float movement.

(b) A steel 'hot rolled structural hollow section' column of length 5.75 m, has the cross-section shown in Figure Q.5(b) and supports a load of 750 kN. During service, it is subjected to axial compression loading where one end of the column is effectively restrained in position and direction (fixed) and the other is effectively held in position but not in direction (pinned). i) Given that the steel has a design strength of 275 MN/m², determine the load factor for the structural member based upon the BS5950 design approach using Datasheet Q.5(b). [11] ii) Determine the axial load that can be supported by the column using the Rankine-Gordon formula, given that the yield strength of the material is 280 MN/m² and the constant *a* is 1/30000.
