Speedometer The 3 design is based on the following basic principles:

1 The design is based on the principle of magnetic field.

Use the same principle as the generator. Is the principle of สนาม แม่เหล็ก The tool will be fed directly. When the object we are interested in rotates through a conductor wire, it induces a voltage induction. The voltage or voltage can be calculated to calculate the rotation of the object we are interested in. Based on the basic output power equations.

Pm (w) = T (Nm) * N (RPM)

Pm is the mechanical force on the output side.

T is torch

N is the magnetic field velocity.

The number of cycles measured is N (RPM) = Pm (w) ÷ T (Nm)

2 The design is based on the principle of light from the infrared sensor.

From the features of the infrared sensor This is a light-sensitive detector. When the infrared sensor receives a certain amount of light. This will cause different voltages or voltages. In this case, the circuit must be connected to make the infrared sensor work. When the infrared sensor detects a change in light intensity, it transmits the signal from this measurement to the electrical signal. It can generate a frequency counter to calculate the roundness of the object that is rotating through the infrared sensor. In measuring around it. Reflector plates must be attached to this rotating object.

3 The design is based on the stochastic phenomenon.

Phenomenon Stoibox Is a phenomenon that studies the rotation of the object through a stoco-bubble that is drilled into the groove and rotates as shown. Just like measuring the speed of photography or video. The frequency of capture is often expressed in units. Frames per second Based on this principle. Modern scopes with flashing lights are commonly used to capture images, or we commonly know that flat light shines on moving objects. Then take the capture frequency (number of frames per second) to calculate the speed of the rotating object. Speedometer design in this way. It's the most advanced of the two. Speedometer Sto bososcope is suitable for many applications. It is a non-destructive measurement of the workpiece is no need to touch the workpiece, it can. Measure around have
