Consider the following transducers: 1. LVDT 2. Piezoelectric 3. Thermocouple 4. Photovoltaic cell 5. Strain gauge Which of these are active transducers?
Consider the following transducers: 1. LVDT 2. Piezoelectric 3. Thermocouple 4. Photovoltaic cell 5. Strain gauge Which of these are active transducers? Correct Answer 2, 3 and 4
Thermocouple and Thermistor are examples of the active transducer and passive transducer respectively.
Transducer:
A transducer is an electronic device that converts energy from one form to another. Common examples include microphones, loudspeakers, thermometers, i.e.
Additional Information
Analog transducers:
- These transducers convert the input quantity into an analog output which is a continuous function of time
- Thus, a strain gauge, an L.V.D.T., a thermocouple, or a thermistor may be called Analog Transducers as they give an output that is a continuous function of time
Digital Transducers:
- These transducers convert the input quantity into an electrical output which is in the form of pulses and its, output is represented by 0 and 1
