Measurement Principle of Laser Photoelectric Speed Sensor
Laser photoelectric speed sensor is a sensor that uses the laser photoelectric effect to measure the speed of an object. The main measurement principle is to determine the rotational speed of an object by utilizing the characteristics of the reflected laser beam on the surface of the object. Specifically, when the laser beam strikes 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 electrical signals, 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 starts to rotate, the laser beam will be reflected back to the sensor, and as the rotation speed changes, the reflected signal will also change accordingly. By processing the reflected signal, the rotation period and angle of the object can be obtained. Thus, the number of revolutions and angular velocity of the object per second can be calculated. These data can be used for control and monitoring in the control system.

In summary, the ROLS-5PW laser optoelectronic 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.

Remarks:

1. TTL signal:

TTL signal is a level signal, which refers to a signal represented by a level value. The TTL level signal specifies that+5V is equivalent to logic "1" and 0V is equivalent to logic "0" (when data is represented in binary). This method of data communication and level regulation is called a TTL (Transistor Transistor Logic Level) signal system.
