Refrigeration - Explain the picture please

[Altairs]

Can someone please explain the picture attached below ? It has been taken from a lab where the supervisor actually failed to tell what is the remote sensing bulb doing attached to a condenser. I would like to know that why is it there and is the wire that is sticking out a capillary tube? If not then where is it or where should it be and what is that wire for ?

My knowledge is that a capillary tube is what goes between a condenser and an evaporator and the remote sensing bulb is a part of the expansion valve/ capillary tube.

Please correct.

That wire is the capillary tube
