- active transducer - passive transducer
- Electrical transducers may be classified as active or passive. The active transducers generate electric current or voltage directly in response to stimulation. An example is the thermocouple; here, the fact that a current will flow in a continuous circuit of two metals, if the two junctions are at different temperatures, is used to generate electricity. The passive transducer produces a change in some passive electrical quantity, such as capacitance, resistance, or inductance, as a result of stimulation. Passive transducers usually require additional electrical energy. A simple example of a passive transducer is a device containing a length of wire and a moving contact touching the wire. The position of the contact determines the effective length of the wire and, thus, the resistance offered to electric current flowing through it. This is the simplest version of what is called a linear-displacement transducer, or linear potentiometer. For practical use, such transducers employ wire-wound, thin-film, or printed circuits to allow for a long resistor within a relatively small device. The longer the resistor, the greater the drop in voltage passing through the device; thus, changes in position are converted to electrical signals.
