advantage

1. Good anti-interference ability

Optoelectronic speed sensors are commonly usedLEDAs a light projection component, there is rarely a situation of light interruption, and there is no risk of bulb burnout or other malfunctions. Besides,Photoelectric speed sensorThe light sources are all modulated in a special way The anti-interference ability will not be affected by ordinary light.

2. Compact structure

The structure of the photoelectric speed sensor is compact, mainly composed of a projection light component, a light receiving component (i.e. photosensitive element and amplifying element), etc. Therefore, the volume design of the photoelectric speed sensor is small and the internal structure is exquisite. Generally, the weight does not exceed 200g, which is very convenient for users to carry, install and use.

3. Good measurement ability

The photoelectric speed sensor can be packaged with optical fibers and is suitable for measuring small objects, especially small rotating bodies. It is particularly suitable for measuring high-precision and small component mechanical equipment. The operation of the photoelectric speed sensor is stable, with good reliability and high measurement accuracy, which can meet the measurement requirements of users.

4. Non-contact tachometer

The photoelectric speed sensor is manufactured using optical principles and belongs to non-contact typeSpeed measuring instrumentIts measurement distance can generally reach about 200mm. The measurement of photoelectric speed sensor does not require contact with the measured object, and does not impose additional load on the measured shaft. Therefore, the measurement error of photoelectric speed sensor is smaller and the accuracy is higher.[1]

There are many methods to directly measure the motor speed, and various methods can be usedphotoelectric sensorHall elements can also be used. The application of photoelectric sensors in industry can be summarized into three basic forms: direct, reflective, and projection.

direct type

The direct photoelectric speed sensor consists of an perforated disk, a light source, a photosensitive element, and a gap plate. The input shaft of the perforated disk is connected to the measured shaft, and the light emitted by the light source is irradiated onto the photosensitive element through the perforated disk and the gap plate, which is received by the photosensitive element and converts the light signal into an electrical signal for output. There are many small holes on the perforated disk. When the perforated disk rotates once, the number of electrical pulses output by the photosensitive element is equal to the number of holes on the disk. Therefore, the measured speed can be obtained by measuring the pulse frequency output by the photosensitive element

Reflective type

Reflective photoelectric sensorMainly composed of the tested rotating component, reflective film (or reflective sticker)reflectionformulaphotoelectric sensorWhen precise positioning can be achieved, symmetrically installing multiple reflective sheets or stickers on the tested component can achieve better measurement results. When the testing distance is close and the testing requirements are not high, only one reflective sticker can be installed on the tested component. At this time, when the reflective sticker on the rotating component passes in front of the photoelectric sensor, the output of the photoelectric sensor will jump once. By measuring this jump frequency f, the rotational speed n can be determined.

n=f

If multiple reflective sheets or reflectors are symmetrically installed on the tested componentstickerSo, then, n=f/N。 The quantity of N-reflective sheets or reflective stickers.

projective

projectivePhotoelectric speed sensorThe reading plate and measuring plate have the same gap between them. The measuring disc rotates with the object being measured, and every time it passes through a gap, it projects from the light source onto the photosensitive element (seePhotoelectric sensor）The light on the surface undergoes a brightness change, and the photosensitive element outputs a current pulse signal (Figure 1). Reflective typephotoelectric sensorThere are reflection marks on the tested axis, and the light emitted by the light source is incident on the tested axis through a lens and a semi transparent membrane. When the rotation axis rotates, the reflectivity of the reflected mark on the projected light spot changes. When the reflectivity increases, the reflected light is projected onto the photosensitive element through the lens and emits a pulse signal; When the reflectivity decreases, there is no signal from the photosensitive element. By counting the signals within a certain period of time, the rotational speed of the shaft can be measured
