a transducer is a device that converts one form of energy to electric energy there are different types of transducers like mic is an acoustic transducer that converts sound energy to electrical energy...resistance changing transducers,inductance changing transducers capacitive type transducer ....change their values in accordance with an analog quantity to b measured like temp etc....this change produces porportional current or voltage which is basically proportional electrical energy
Transducer, in electronics, a device that converts electric energy into some other form of energy, or vice versa. Transducers are used in sound systems, in video equipment and in many measuring devices. A transducer used in a measuring device produces an electric current proportional to the strength or intensity of the physical quantity-such as heat, light, or mechanical stress-to which the transducer is subjected. Piezoelectric crystals (crystals that produce an electric current when deformed) and photoelectric cells are transducers; so are loudspeakers, which produce sound from electric energy.

What is an optical transducer?
A optical current sensor is used to measure current, In CT there is a use of iron core but as the rating of current to be measured increseS the CT saturation occurs this will leads to inaccurate representation of The current, but this does not ocur in OCS ,It uses light to measure the current,Current flowing in a conductor induces a magnetic field, which, through the Faraday effect, rotates the plane of polarization of thelight traveling in a sensing path encircling the conductor.thus by measurin this rotation the current is measured.(by GAURAV GAUR LNT, INDIA)
Explain differancnce between instrument current transformer and measuring current transformer?
Current transformer is a device used to measure the flow of current through a power system and the measured current is inputted to a protective relay system. It is used to detect system malfunction. Current transducer is a device used to measure AC and DC current based on the halt-effect technology.
Who invented transducer?
transducer was invented by
What are digital transducers?
a transducer which can measures a physical quantities and and transmit the informations as coded digital signalsrather then as continuous varying current/ voltage.
What is pressure transducer?
please give a simple defineatoin of transducer.

What is transducer and how it may be used to measure displacement?
Transducer is a device which convert physical signal into electrical signal ( current/voltage/resistance). for linear measurement we can use LVDT (Linear Variable Displacement Transducer/ Linear Variable Differential Transformer). and for rotary measurement we can use RVDT (Rotary Variable Differential Transformer)
What is meant by Voltage Transducer?
A transducer converts a form of energy to another form (usually voltage). e.g. A Current Transducer would read a current, and output a range of voltage that's related to the current. A voltage transducer is used when the voltage is too high or too low to be detected. A voltage transducer essentially transforms the voltage signal to something readable (e.g. Transforming 0~1000V to 0~5V)

What is potentiometric transducer?
It converts linear or angular motion into a changing resistance which may be converted directly to voltage and/or current signals
What is an instrument for measuring wind force?
You can measure wind force with force transducer.
Why potentiometer is called passive transducer?
because potentiometer generate a own current
How do you measure thickness in ndt?
The best way to measure thickness is to use an ultrasonic transducer. You use the back reflection to figure out the thickness.
What is an example of digital transducer?
A digital transducer is used to measure physical quantities and then transmit it as a coded digital signal. Examples include shaft encoders, digital tachometers, and limit switches.
What is an IP transducer?
An I/P transducer is a device that converts a 4-20mA current (I) signal into a pressure (P) signal of 3-15psi or 20-100kPa usually to operate pneumatic control valves.
How do you measure acoustic waves?
use a transducer like microphone or sth to convert it to electric signal ,now u can measure electric signals easily....
