In the general case, 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. At the risk of getting too abstract, a transducer converts an input to an output that can be exploited to accomplish the sensing mission.
For example, a pressure sensor may use a diaphragm and/or strain gage to "detect" pressure differential across the diaphragm, but he complete sensor will additionally consist of a display element and the electronics required to energize and condition the output of the detecting transducer, as well as the elements required to house and drive the display feature.
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".
In special cases, a sensor and a transducer can be the same. For example, a bi-metallic spring element can both detect temperature change, and may well be the entire sensor if a pointer is attached to the bi-metalic spring.
According to the instrument society of America-- " A Sensor or Transducer is a device which provides a usable output in response yo a specified measurand"
Here the o/p is defined as an electrical quantity and measurand is a physical quantity .but there is a small difference between them.... Sensor is an element that senses a variation in input energy to produce a variation in another same form of energy. Whereas , transducer usage transduction principle to convert a specified measurand into usable output.
ex.... A properly cut Piezoelectric crystal can be called a sensor and it becomes a transducer with appropriate electrodes and input/output mechanism attached to it.
Transducer since it transform heat into electrical voltage
today the general rule of thumb is that if the pressure sensor has a millivolt (e.g. 30mV or 100mV) or non-amplified output it is a pressure transducer. If the pressure sensor has a voltage (e.g. 0-5Vdc, 0-10Vdc or 1-5Vdc) output it is an amplified voltage output pressure transducer. If a pressure sensor has a current loop output (e.g. 2 wire 4-20mA or 3 wire 0/4-20mA) it is a pressure transmitter. Simply we can tell as Transducer: Any physical Quantity is converted into Electrical Signal. Transmitter: to make the amplified RF electrical signal to radiation with help of Electric and maganetic signal.
A limit switch turns on or off when the object being sensed reaches a specific location.A proximity sensor returns an analog signal indicating how far the object is from the sensor.

please give a simple defineatoin of transducer.
No There is not much a difference you can draw between a Sensor & a transducer, as both does the same thing of measuring an energy in form & converting it to other form. But a transducer will make an additional effort to convert the energy into measurable electrical form & then then transmitting!!!! Pls coment
It is wrong.
NTC is negative temp coefficient transducer,working with resistor while lm 35 is an IC type transducer
Transducer since it transform heat into electrical voltage
The engine computer uses the coolant temperature sensor and the air conditioning pressure transducer to decide when to operate the radiator fan. The coolant temperature sensor is located near the thermostat housing on top of the engine. The ac transducer is on the line between the compressor and condenser.The engine computer uses the coolant temperature sensor and the air conditioning pressure transducer to decide when to operate the radiator fan.

transducer
9 crystal transducers provides a wider beam and greater signal integrity
please help me to understand the word transducer
An transducer converts one form of energy into another. eg. door bell(electrical energy - sound energy) An actuator transforms electrical energy into mechanical energy. eg. motor An actuator is essentially a transducer but a transducer need not be an actuator.
It is a slang tern given to a Differential Pressure Sensor or Transducer.

The temp sensor is in the transducer inside the transmission on the vavle body. The transducer is usually gold and has a 4 wire oval connector. the temp sensor is built into it
