Laser speed sensor ROLS-5PW

Laser speed sensor, also known as speed photoelectric sensor, speed sensor, or laser speed photoelectric probe, emits laser through a laser emitter to irradiate a rotating object. The object reflects the laser back, and the laser receiver filters and amplifies the reflected pulse signal. Capable of measuring the rotational speed of various rotating objects from a distance.

Laser photoelectric speed sensor is a measurement principle

Laser photoelectric speed sensor is a sensor that uses laser photoelectric effect to measure the speed of an object. The main measurement principle is to use the characteristics of the reflected laser beam on the surface of an object to determine its rotational speed. Specifically, when the laser beam is irradiated onto the surface of an object, it will be reflected back to the sensor. The photosensitive element in the sensor can convert the reflected laser signal into an electrical signal, and by processing these electrical signals, the rotational speed of the object can be determined.

When using a laser photoelectric speed sensor, it is necessary to fix the sensor on the object to be measured and ensure that the laser beam is perpendicular to the surface of the object. When an object begins to rotate, the laser beam is reflected back to the sensor, and as the rotation speed changes, the reflected signal also undergoes corresponding changes. By processing the reflected signal, the rotation period and angle of the object can be obtained. Thus, the number of rotations and angular velocity of an object per second can be calculated. These data can be used to implement control and monitoring in the control system.

In summary, the ROLS-5PW laser photoelectric speed sensor is a high-precision, high-sensitivity, and high reliability sensor that measures the speed of an object based on the principle of photoelectric effect. Its measurement principle is simple, easy to operate, and has high accuracy, which can be widely applied in industrial automation control, mechanical manufacturing, aerospace and other fields.
