What is the difference between a transducer and a sensor of fuel dispensers for sale?

Mac 6 2021-11-30 14:36:14

Transducers and sensors are used in many mechanical parts. For our fuel dispensers for sale, such as EG1 (https://en.chinaeaglestar.com/products/showproduct.php?lang=en&id=25), EG3 (https://en.chinaeaglestar.com/products/showproduct.php?lang=en&id=15), EG5 (https://en.chinaeaglestar.com/products/showproduct.php?lang=en&id=16), EG6 (https://en.chinaeaglestar.com/products/showproduct.php?lang=en&id=22) and EG7 (https://en.chinaeaglestar.com/products/showproduct.php?lang=en&id=18), sensors also play an important role.

 

The brief description of fuel dispensers for sale sensors and transducers are as follows:

Sensor - As the term suggests, it is a body which reacts to a physical, chemical or biological condition. It senses. It can be considered as a detector.

Transducer - The conversion of energy from one form to another is known as Transduction. A transducer serves for this purpose.

 

Now why there is confusion is that:

A fuel dispensers for sale sensor can sense in any form (usually electronic), i.e. due to some mechanical change, it can react in electrical form. Thus, there is a conversion, similar to that of a transducer.

A classic example would be a thermocouple. Or a pressure sensor which might detect pressure and convert it into electric current (3-15psi to 4-20ma).

 

fuel dispensers for sale transducer is more than a sensor. It consists of a sensor/actuator along with signal conditioning circuits.

A signal conditioning circuit, by the name is a circuit which conditions the signal so that it is strong enough for further processing. A system might contain many stages before the signal finally reaches its destination to derive meaningful information.

 

So, one way to define is that the output from a sensor may or may not be meaningful, i.e. most of the times it needs to be conditioned and converted into various other forms. The transducer output is always meaningful.

 

The output of a motor is meaningful. The output of a loudspeaker is meaningful. They are transducers. A 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.

 

We can say that every transducer is also (or has) a sensor but every sensor needs not be a transducer. Sometimes it is.

 

A compass is a simple sensor of magnetic north, wherein the magnetic element in the compass is the transducer.
