Transducers
Transducers are electrical devices that play vital functions in control systems, measurement, and automation. They transform one energy form to another. More specifically, transducers change physical quantities to proportional electric quantities (such as electric current and voltage). Examples of physical quantities are temperature, level, displacement, and pressure. When these physical forces are converted into electrical signals, they become easier to manage and use for measurement. Read More
Parts
Transducers have two essential parts: the sensing element and the transduction element.
- Sensing elements respond to physical forces.
- Transducing elements, also known as secondary transducers, transform the sensing elements’ outputs to electrical signals.
Types
Transducers are categorized into two types: output and input transducers.
- Output transducers are also called actuators. These devices control a system, and are operated by an energy source. Pneumatic pressure, hydraulic fluid pressure, electrical current, and mechanical force are just some examples of sources. In other words, actuators receive electrical signals and transform these into other forms of energy. For example, a loudspeaker transforms electricity to sound.
- Input transducers are the opposite of output transducers. They transform quantities to resistance or voltage/electrical signals. These transducers, therefore, receives physical energy and then transforms it to readable electrical signals. A common example is the microphone, which takes in physical sound waves, and transforms them to electrical signals that are then moved through cables or wires. Another input transducer is an LDR or light dependent resistor, which transforms light brightness into resistance.
Transducers are also categorized according to the quantity to be measured. Examples are oscillator transducers, pressure transducers, temperature transducers, inductive transducers, displacement transducers, and flow transducers.
Transducer Applications
Transducers are used in/for:
- Acceleromyograph or the process of detecting muscle movements
- Ultrasound machines
- Converting electromagnetic waves to electrical signals in antennas
- Measuring engine load
