What is a Transducer?
A transducer is an electronic device that converts energy from one form to another. The process of converting energy from one form to another is known as transduction.
Why do we need a transducer?
To determine the exact magnitude of physical forces such as temperature and pressure is difficult. But, if these physical forces are converted into an electrical signal, then their values can be easily determined using a meter. The primary function of transducers is to convert a physical force into an electrical signal so that it can be easily handled and transmitted for measurement.
Advantages of converting a physical quantity into an electrical signal
Here, we have listed the various advantages of converting a physical quantity into an electrical signal:
- Electrical signals are easily transmitted and processed for measurement.
- Electrical signals process less friction error.
- Small power is needed to control the electrical systems.
- Amplification and attenuation of electrical signals are easy.
- The measuring instrument used for measuring the electrical signal is very compact and accurate.
Parts of Transducer
A transducer consists of the following two important parts:
- Sensing element
- Transduction element
Transducers have other vital parts such as signal processing equipment, amplifiers and power supplies.
Sensing Element
It is the part of a transducer that responds to the physical sensation. The response of the sensing element depends on the physical phenomenon.
Transduction Element
The transduction element of the transducer converts the output of the sensing element into an electrical signal. The transduction element is also called the secondary transducer.
Types of Transducers
There are two types of transducers, as follows:
- Input Transducer
- Output Transducer
What is an Input Transducer?
An input transducer or a sensor takes in physical energy and converts it into an electrical signal that can be read. A microphone, for example, converts physical sound waves into an electrical signal that can be transferred through wires.
Applications of Transducer
- A transducer measures load on the engines
- They are used to detect the movement of muscles; this process is known as an acceleromyograph.
- Transducers are used in an ultrasound machine.
- The transducers in a speaker convert electrical signals into acoustic sound.
- A transducer is used in the antenna to convert electromagnetic waves into an electrical signal.
Difference Between a Transducer and a Sensor
A sensor is a device that measures a physical quantity. For example, in a mercury thermometer, the mercury simply expands when the temperature rises to give a reading to the user. Here there are no electrical inferences or changes. On the other hand, a transducer measures similar quantities as a sensor but the signal in a transducer is converted from one form to another. This is the reason why transducers are also referred to as energy converters.
Factors Influencing the Choice of Transducer
The choice of the transducers used for measuring the physical quantity depends on the following factors.
- Operating Principle – The transducers are selected by their operating principles. The operating principle may be resistive, inductive, capacitive, optoelectronic, piezoelectric, etc.
- Sensitivity – The sensitivity of the transducer is enough for inducing the detectable output.
- Operating Range – The transducer must have wide operating ranges so that it does not break during working.
- Accuracy – The transducers gives accuracy after calibration. It has a small value for repeatability which is essential for industrial applications.
- Cross Sensitivity – The transducers gives variable measured value for the different planes because of the sensitivity. Hence, for accurate measurement, the cross-sensitivity is essential.
- Errors – The errors are avoided by taking the input-output relations which is obtained by the transfer function.
- Loading Effect – The transducers have high input impedance and low output impedance for avoiding errors.
- Environmental Compatibility – The transducers should be able to work in any specified environment like in a corrosive environment. It should be able to work under high pressure and shocks.
- Insensitivity to Unwanted Signals – The transducer should be sensitive enough for ignoring unwanted and highly sensitive signals.
- Usage and Ruggedness – The durability, size and weight of the transducer must be known before selecting it.
- Stability and Reliability – The stability of the transducers should be high enough for the operation. And their reliability should be good in case of failure of the transducer.
- Static characteristic – The transducer should have a high linearity and resolution, but it has low hysteresis. The transducer is always free from the load and temperature.
