A tachometer is a device that measures the instantaneous speed of rotation. It includes a totalizer, which measures the total number of revolutions. It is used to measure the rotational speed of engines, motors, generators, etc.
In the past, analog tachometers were used to measure rotational speed by converting mechanical phenomena into frequency, but in recent years, optical tachometers have become the mainstream, as they are non-contact and can instantly measure rotational speed.
Tachometers are used to measure the rotational speed of various machines. An example is an engine. The rotational speed of an engine has a great deal to do with its power and torque. If the speed is too high, the engine loses stability and may be damaged. In addition, the rotational speed must always be measured in order to convert the speed into gearboxes of automobiles and other vehicles.
Furthermore, they are also used to verify the rotational speed of air conditioning and ventilation equipment. These rotational speeds are directly related to performance and are therefore useful in terms of performance evaluation.
Tachometers have long been used to measure rotational speed based on mechanical action, but in recent years, optical tachometers have become the norm.
Optical tachometers are non-contact and do not damage or wear out the tachometer or the object being measured. They also use lasers or LEDs as the light source. These are used in different ways depending on the application.
Here we introduce their applications and features:
