Contactless tachometer

Digital contactless tachometer for speed measurement with optical sensor, with circuit diagram and code using microcontroller. Here is the circuit diagram and working of contactless digital tachometer using 8051 microcontroller it helps to measure the speed of an electric motor.

Hey friends, i should have posted this project last month itself but there was some problem with the circuit , author of this project did an exellent. Contactless digital tachometer using 8051 a three digit contact less digital tachometer using 8051 microcontroller which can be used for measuring the revolutions/second of a rotating wheel, disc, shaft or anything like that is introduced in this project.

Contactless tachometer using arduino and ir sensors to calculate the rpm of the rotating object here u get complete detail like circuit diagram and codes. Wholesale supplier of digital tachometer - non contact tachometer, contactless tachometer and rpm tachometer offered by precision scientific instruments corporation, delhi. This project is used to develop a contactless tachometer for bldc motor in some applications, where it is not feasible to measure the speed for safety and technical reasons.

This contactless speed sensing device (tachometer) for bldc motor is planned to measure the motor rotational speed without any contact from certain distance.

Contactless tachometer

contactless tachometer Tachometer is a device that measures the rotational speed of any shaft or disc the unit of the measurement is usually revolutions per minute or rpm the traditional method of measuring rpm of a rotating shaft was based on velocity feedback concept where a dc generator is hooked to the rotating shaft so that the voltage induced across the generator’s terminals is proportional to the speed of .

Hello friends this is my another instructable contactless tachometer using arduino and ir sensor i inspired to make this project when i need to measure the rpm of.
