Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If equipped with digital output interface
Digital-output transducers may be seen as instrument parts under precision measurement instruments.
If primarily functioning as inductors
If emphasis is on inductive components rather than transduction function, it moves to transformers/inductors.
If installed in valves or taps
Valve-position transducers are classified with valves if designed for that specific end-use.
