What is the difference between stroboscope and tachometer?

It is fascinating to find the speed or velocity of moving objects, especially objects moving in periodic motion. Stroboscopes and tachometers are instruments that are concerned with the study of such motion. 

To understand the difference between both instruments we must be familiar with the functioning and usage of both instruments. So, let us understand what a stroboscope and tachometer are. 

What is a Stroboscope and how does it work? 

What is a Stroboscope

Have you felt amazed to observe that when a car runs in a particular direction, its wheel seems to be rotating opposite to that direction? If yes then you have already watched the stroboscopic effect. It can be understood by understanding the stroboscope and working principle of a stroboscope. 

Stroboscope’s working principle is simple to understand. It functions on the basis of stroboscopic effect. A stroboscope is a device that is used to study the periodic motion of an object. When an object moves in a periodic motion, a stroboscope is used to measure the frequency or speed of that moving part.

A stroboscope emits flashes at the moving objects at some frequency. If the frequency of flashes is equal to the frequency of rotation then the object seems to be in a stationary position. An observer can adjust the frequency of flash to bring it equal to the frequency of the rotating object.

What are a Tachometer and its working principle?

What are a Tachometer

Tachometer or revolution counters are instruments used to measure the speed of a rotating shaft of any machine. Tachometers are commonly used in automated vehicles. In such vehicles, the tachometer helps in the working of the engine by measuring the rotational speed of the engine.

A tachometer can also be used to measure a safe range of engine speed. Tachometers find rotational speed in RPM i.e revolution per minute. In traffic engineering, Tachometers have a significant value.

Tachometers can be classified into various subtypes based on their functioning and structuring. 

Tachometer types –

Tachometer types

Analog tachometer –

It comprises of a needle and a dial-type interface. This device does not offer storage of readings and is unable to compute details such as average and deviation.

Digital tachometer –

It comes with an LCD or LED readout along with a a storage memory. The device is capable of performing statistical operations. It is is finally suitable for precise measurements and monitoring of time-based quantities.

Contact tachometer –

It remains in contact with the rotating shaft. The device uses an optical encoder or magnetic sensor for data acquisition.

Non-contact tachometer –

It does not remain in touch with the rotating shaft. It uses a laser or optical disk for data acquisition.

Non-contact Types –

  • Laser tachometer
  • Optical tachometer

Smart projects for engineering students

Smart projects for engineering students

Engineering is more than just a profession. It is concerned with bringing innovation and invention to a country. Engineers pave the way for development and therefore, a considerable amount of emphasis should be given to their learning. 

Project Bot emphasizes on smart learning of engineering students by providing smart projects. Our Stroboscope and Tachometer projects help students to understand the functions of these instruments. Through these smart DIY projects students get to learn about the technology in a comprehensive way. Our projects are highly reliable and easy to use. Learning becomes fun and easy when students work on these projects for a practical understanding of complex concepts. Through Stroboscope and Tachometer projects, students can develop a deeper and thorough understanding of their working principle. 

For nurturing budding scientists, it is imperative that they learn from the best. Our smart projects are designed and curated by a team of experts after due deliberation and discussion. Working on these smart projects can ensure students a firm grasp of all important concepts. While preparing our project related to Stroboscope and Tachometer, our team has kept the curriculum under due consideration. Also, our projects reflect recent trends in the industry. Therefore, students become industry-ready and skilled human resources from working on smart projects. Our projects not only make students smarter but also prepare them to be the future bearer of innovation. 

Qualitative learning with Stroboscope and Tachometer projects

Qualitative learning is defined by developing conceptual knowledge as well as skills. Qualitative learning makes your child different and unique from the crowd. Project Bot’s Stroboscope and 

Tachometer projects enhance the capabilities of students by focusing on their holistic growth. Working on our products gives students first-hand experience with the latest technology. When students work on these projects they apply theoretical knowledge to practical use which gives them practical skills. 

Our project aims to create an environment where children feel encouraged to explore. In 

Stroboscope and Tachometer projects students are required to work in groups and study about them. Working in groups makes students team players. It is essential that students learn from the best in order to gain expertise. Expertise comes with critical thinking and problem-solving ability. Through our project students are motivated to bring effective and creative solutions to real-life problems. When students indulge in our projects their mind gets sharpened which results in their intellectual development. 

Engineers lead a nation on the way to development. Through our projects, students learn to be innovative and get prepared for industry. Students feel confident when they understand concepts of science through our super fun projects. Our Stroboscope and Tachometer projects are efficient in inculcating a scientific approach to students’ behavior.

Delivering value to teachers and parents 

Providing the right kind of guidance is the prime concern of every parent for their children. To make a parent’s job easy our project comes in handy. Project Bot’s DIY Stroboscope and Tachometer projects are the best quality projects . Materials used in making these projects are of high-quality material which ensures the safety of projects in adverse conditions. Students can easily carry and present these projects in the classroom, exhibition, science fair, etc. To ensure the safety of students while experimenting, our projects are equipped with safety tools. Parents don’t have to brainstorm for hours over project options anymore. Avail these super-efficient projects by Project Bot to make your child smart. 

With investment comes expectations. When students or teachers purchase science projects they expect the value of money for their investment. Project Bot meets the expectation of teachers and students in a lot of ways. We have kept the standard curriculum and trends of the industry in consideration while making these projects. This ensures that young minds get to know what is happening in real-life scenarios. Our projects make students industry-ready. Through our projects, teachers can ensure maximum engagement of students in class. These projects invoke the curiosity of children and add  a scientific approach to their understanding level.
