The description clearly refers to an inductive transducer. Instead of the suggested LVDT design, it sounds more like center-tapped coil, that works in combination with a moving core and a differential inductance bridge.
All information collected together..........................
Inside it there are two small (tiny) transformers whose one wire is common to each other and there are two other wires (one for each).
They are usually connected with a shaft (roller) that rotates and take the packaging film to the rewinding shaft.
there's just output cable having three wires coming out from the two transformers
Do You have some number on it? This no. is mentioned on it , BS 50K
they are two on each shaft (roller) one on the right side and other on the left side .......
HAN MI is the brand name of strain gauge which are present on both sides of the roller.
The machine is very old of its kind
The conclusion from previous.................................

Like FvM wrote in previous post " three-terminal inductive sensor without an excitation coil."
I agree that .
another possible component is Strain Gage Transducer one half bridge per side.
For closer examination we need to know manufacturers and the exact types and models of devices.
Good pictures of components could possibly help.

Still I am wondering what are those " 2 small transformers inside it" ????

As kak111 said 90% information is available in the datasheet of a components. Best always consult it first.
how to test " under pillow block load cell " GTSA50M ?
can't you take any example ? or from the link that i have provided you ..........
