What is a Transducer? An Explanation

A transducer is an electronic device that converts energy from one form to another, the electrical signal is then turned into a usable direct current or voltage that is easily measured. Some examples of transducers include microphones and loudspeakers.

There are two different types of transducers an input transducer which is a sensor and an output transducer which is an actuator. We offer linear position transducers and pressure transducers here at variohm. Click below to view the different product ranges:

What is an Input Transducer?

An Input transducer, or sensor, takes a form of physical energy and converts it into a signal which can be read.  For example, a microphone takes physical sound waves and turns those into an electrical signal which can be transferred through wires to the amplifier.

A pressure transducer is also a type of Input transducer. They convert physical force into a number or reading that can be measured and understood.

What is an Output Transducer?

An Output transducer, or actuator, does the opposite of an Input transducer. It takes electrical signals and converts them into another form of energy. For example, a lamp converts electricity to light and a motor converts electricity into motion.

What is a Transducer used for?

Some examples of transducers in applications include:

  • Microphones
  • Loudspeakers
  • Thermometers
  • Ultrasound Machines
  • Repeaters
  • Construction & Agricultural Appliances
  • Automotive 

Types of Transducer from Variohm

We can offer different types of transducers. We have a range of pressure transducers, which are used in many industries including; automotive, off-road, construction and agricultural appliances.

Pressure transducers are types of Input Transducers, they work by responding to force applied to them and converting the force into an electrical output.

We also offer position transducers, these come in the form of linear position transducers, cable extension transducers and in-cylinder linear position transducers.

Position Transducers are also types of Input Transducers. They convert mechanical motion into an electrical output.
