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.

Is thermocouple a sensor or a transducer?
Transducer since it transform heat into electrical voltage
What is difference between transducer and transmitter?
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.
What is the difference between magnetic pick up and proximity sensor?
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.

It is wrong.
What is the difference of ntc sensor and lm35?
NTC is negative temp coefficient transducer,working with resistor while lm 35 is an IC type transducer
Where is the switch that turns on radiator fans on 1995 Chrysler new yorker?
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.

What is the another name for a sensor?
transducer
Is there a difference between a photo transducer a photo sensor and a photo electric transducer if there is one what is it?
These terms are often used interchangeably to refer to devices that convert light into an electrical signal. A phototransducer typically refers to a device that can convert light directly into an electrical signal. A photosensor generally refers to a broader category of devices that can detect light and initiate a specific response, which may or may not involve converting light into an electrical signal.
What is the difference between 9 crystal transducer and 7 crystal transducer?
9 crystal transducers provides a wider beam and greater signal integrity
