Categories Of Transducers

A transducer is a device that transforms energy from one form into another. There are several excellent examples of transducers that can assist you in knowing this device.

Typical Cases

Speaker: the speaker is a cone that vibrates and goes. The vibration and motion creates pressure waves from the air (also called sound waves). The speaker is an electromechanical transducer that converts electrical energy into mechanical energy.

Ears and brains did you know that your own ears and brains are transducers of some type? Both get pressure waves and convert them into electrical brain impulses that enable you to perceive noise.

Light bulb: it converts electrical energy to light energy.

Water heaters: a water heater includes a tube in which cold water flows before it’s heated. Inside the tube there is an impeller that spins just once you turn to the hot water.

After the impeller spins, then it activates a sensor that switches on the electrical current which heats the water as it flows through the heating elements in the water heater. The impeller in this circumstance is your transducer.


Transducers are categorized in several Distinct ways which include:

Main: chief transducers work on the principle that the input detector finds or sensations an immeasurable data like heat, mass, thickness and density. The detector then converts the received signal into readable information that’s controlled through an on/off switch. Fantastic examples of main transducers are thermocouples and thermistors.

Active and passive: they are categorized based on the sort of energy sources they’ve. Passive transducers create power output signal from real mechanisms like outside power. Fantastic examples are resistive, inductive and capacitive transformers.

Lively transducers on the other hand get their electricity from physical heaps. Then they create their own voltage and current outputs. Fantastic cases of busy transducers are piezoelectric crystals, thermocouples and photovoltaic cells.
