MOVING IRON TRANSDUCER.
TRANSDUCER:-
The device which converts the one form of energy into another is known as the transducer. The process of conversion is known as transduction. The conversion is done by sensing and transducing the physical quantities like temperature, pressure, sound, etc.
The electrical transducer converts the mechanical energy into an electric signal. The electrical signal may be voltage, current and frequency. The production of the signal depends on the resistive inductive and capacitive effects of the physical input.
NEED OF TRANSDUXXX:-
XX is quite difficult to determine XXX XXXXX magnitude XX XXX XXXXXXXX XXXXXX like XXXXXXXXXXX, pressure, XXX. XXX if XXX physical XXXXX XX XXXXXXXXX XXXX an XXXXXXXXXX signal, XXXX XXXXX XXXXX XX easily XXXXXXXX XXXX XXX XXXX XX the XXXXX. XXX transducers convert XXX XXXXXXXX forces XXXX an XXXXXXXXXX signal XXXXX XXX XXXXXX be XXXXXXX and transmitted for XXXXXXXXXXX.

The XXXXXXXXX are the XXXXXXXXXX XX XXXXXXXXXX the physical XXXXXXXX into an electrical signal.
XXX attenuation and amplification of XXX electrical XXXXXXX XXX very easy.The XXXXXXXXXX XXXXXX produces XXXX friction XXXXX.XXX small XXXXX XX required XXX XXXXXXXXXXX XXX electrical systems.XXX XXXXXXXXXX XXXXXXX XXX XXXXXX transmitted and processed for XXXXXXXXXXX.The XXXXXXXXX used XXX measuring XXX XXXXXXXXXX XXXXXX XX very compact XXX accurate.The XXXXXXXXXX XXXXXXX are XXXX in telemetry.
XXXXX OF TRANSDUCER:-
XXX XXXXXXXXXX XXXXXXXX XXX XXXXXXXXX parts.
1.XXXXXXX Element
2. XXXXXXXXXXX XXXXXXX.
1.XXX transducer XXX XXXX XXXXX parts XXXX amplifiers, signal XXXXXXXXXX XXXXXXXXX, XXXXX supplies XXXXXXXXXXX XXX XXXXXXXXX sources, etc.
X.XXXXXXX or Detector Element – It XX the XXXX XX the transducers which XXXX XXX XXXXXXXX to XXX XXXXXXXX XXXXXXXXX. The response of the sensing element depends on XXX XXXXXXXX XXXXXXXXXX.
The transducer has many other parts like XXXXXXXXXX, XXXXXX processing XXXXXXXXX, power XXXXXXXX XXXXXXXXXXX XXX XXXXXXXXX sources, etc.
XXXXXXXX or Detector Element – It is XXX part of XXX transducers XXXXX give XXX response XX XXX XXXXXXXX XXXXXXXXX. The response XX XXX XXXXXXX XXXXXXX XXXXXXX on the physical phenomenon.
X.XXXXXXXXXXXX Element – The XXXXXXXXXXXX XXXXXXX converts XXX output of XXX sensing element XXXX an XXXXXXXXXX XXXXXX. This element is also XXXXXX the XXXXXXXXX XXXXXXXXXX.
XXXXXX XXXX XXXXXXXXXX:-
The instrument in which the XXXXXX iron is used for measuring the XXXX XX current or voltage is XXXXX as the moving XXXX instrument. It works on XXX XXXXXXXXX that the XXXX place near the XXXXXX XXXXXXXX XXXXXXX it. The XXXXX of XXXXXXXXXX XXXXXXX on XXX strength of the XXXXXX field

XXXXXX X XXX telephone earpiece principle. The magnetized diaphragm XX made from iron or a XXXXXXXX alloy and is XXXXX by the attraction or repulsion XX the core as XXX XXXXXX XXXXXXX XXXXX in XXX coil. XXX XXXXXXXX is XXXX sensitive, XXXXXXXX XXX sound quality is XXX.
XXX first type XX XXXXXXXX, as XXXXXXX to XXX XXXXX telephones, was a XXXXXX-iron XXXX, and XXXX XXXXXXXXX has XXXX extensively used ever XXXXX. XX applied XX XXX XXXXXXXXX, XXX earphone uses a XXXXXXXXXX metal XXXXXXXXX (XXXXXX X) so that XXX XXXXXXXXX XX XXXXXXXXXXXXX of the fixed coil XXXX ensure the XXXXXXX movement XX the diaphragm. Without this fixed XXXXXXXX XXXXXXXXXXXX, XXX diaphragm XXXXXXXXX XXXXX XX twice the frequency XX XXX electrical XXXXXX. XXXXXXXXX XX XXXX type are XXXX XXXXXXXXX, but the XXXXX XXXXXXX XX XXXX XXXX XXXXXXX XX the comparatively XXXXX diaphragm that causes unavoidable resonances.
XXXXXXXXX XXXXXX-XXXX XXXXXXXXX are still in use, particularly where XXXXX quality is XXX XX XXX XXXXXXX XXXXXXXXXX, but XXX principle XXX died out as far XX XXXXXXXXXXXX are XXXXXXXXX. XX one time, moving-iron XXXX- XXXXXXXX, XXXXX were XXXXXXXXX earphone XXXXX XXXX a cone XXXXXXXX, XXXX XXXX, but these were XXXX replaced by the moving-coil type that provided XXXXXXXXXX XXXXXX XXXXX XXXXXXX.
The XXXXX XXXXXX XXXX XXXXXXXXXX, the telephone XXXXXXXX or earphone, XXXXXXX with the first XXXXXXXXX systems in the 1870s. XXXXXX iron XXXX loudspeakers XXXXXXXXX XXXX XXXXXXXXX XXXXX XXX first XXXXXXXXXX device which XXXXX drive a XXXXXXX, XXX triode XXXXXX XXXX, XXX XXXXXXXXX XXXXXX XXXX. XXXX XXXX XXXX in XXXXX XXXXXXXXX and the XXXXX XXXXXX address XXXXXXX. Moving XXXX XXXX XXXXXXXXXXXX appeared around XXXX. XXXXXX 1930 they were XXXXXXXX by XXX moving coil cone loudspeaker developed in XXXX by XXXXXX Kellogg XXX Chester XXXX. XXXXX the XXXXXX XXXX XXXXXX XXXXXXXXX XX still used in some XXXXXXXXX and tiny XX speakers.
XXXXXX IN MAGNETIC SYSTEM:-
Energy XXXXXXXXXXXX law:-
VIdt = Fdx + d(X/XXXX)
XXXXXXXXX XXXXXXX (changing L):-
V = d/dt¢ = d/dt (LI)
Force XXXXXXXX (changing X):-
Id( LI)= XXX+ XXXX + I2/2dL
Simplifying:-
XX/XX= XXX
XX
X = (I2/2) (XX/dX)
