Answer / koti

sensor just sens the physical quantity(parameter).it does
not convert to any form.
transducer=sensor+transduction element.it converts one form
of energy into another form.

Answer / ankur

sensor is nothing but just a primary element which senses
any physical phenomenon or it gives an indication in any
change of the physical phenomenon.
while..
transducer converts one form of energy to the another form
of energy.
EVERY TRANSDUCER IS ALWAYS HAVING A SENSOR BUT EVERY SENSER
DOESNT NEED TO B A TRANSDUCER.

Answer / abdus sattar mollah

sensors: which can respond to a change in physical
parameter (in its surruonding) and produce a change in a
physical parameter that can be sensed.eg:when a peizo
electric crystal is supplied a potential difference then
its change its dimension.

Transducer:which convert an change in physical parameter
(involving some form of energy) into some USEFUL energy's
form.Eg:peizoelectric crystal with electrodes is a
transducer.

Answer / ashokkumar

Sensor is a device which measures a physical quantity like
vibration ,temperature,humidity,pressure,speed etc and
converts in electrical form depending on the sensor
properties whether active or passive type.


Transducer is a device which converts one form of energy
into another form.That may be from voltage to current or
temperature to voltage.

So all sensor can be transducer but all transducer can't be
sensor.

Answer / guest

sensor: which converts one physicalquantity into electrical
quantity. Transducer which converts one form of energy into
another form.Example pressure Measurement{BOURDAN TUDE}.

Answer / binay das

a sensor is the complete assembly required to detect and communicate a particular event, while a transducer is the element within that assembly which accomplishes only the detection of the event.

A compass is a simple sensor of magnetic north, wherein the magnetic element in the compass is the transducer or "north detector" and the needle, housing and compass face comprise the remainder of the "north sensor".

Answer / sushmareddy

A device that measures or detects a real-world condition,
such as motion, heat or light and converts the condition
into an analog or digital representation. An optical sensor
detects the intensity or brightness of light, or the
intensity of red, green and blue for color systems.

Transducer which convetrs 1 form of energy in another form

Answer / ahmed saied

sensor converts physical quantity into signal which can be read by user or instrument and this signal is usually electrical digital signal like preasure sensor that when preasure reaches 4 bar sensor activate valve to be opened or closed.

transducer converts energy from one form to anthor such as
preasure transducer when preasure reaches 4 bar transducer converts it to electrical output current 0-20mA or voltage 0-5V

Answer / sandiv

transducer which converts the non electrical energy in to
electrical energy,bt not in a opposite manner.
sensor is a device that detects a change in a physical
stimulus and turns it into a signal which can be measured
or recorded

Answer / ram lakhan meena

sensor is a device which only sense any single it does not change any physical quantity whereas transducer sense and convert any non electrical physical quantity into an electrical quantity.
