1. Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction, and the function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into two types: measurement standard and mechanical displacement. According to the different forms of the variable to be measured, the displacement sensor can be divided into two types: analog and digital. The analog type can be divided into two types: physical type and structural type.
2. Most of the commonly used displacement sensors are analog structural types, including potentiometer displacement sensors, inductive displacement sensors, self-leveling machines, capacitive displacement sensors, eddy current displacement sensors, Hall displacement sensors, etc. An important benefit of digital displacement sensors is the ease of feeding signals directly into the computer system. These sensors are developing rapidly and are becoming more and more widely used.
3. During the displacement sensor, the grating sensor has been widely used in machine tool processing, testing instruments and other occupations because of its easy digitization, high precision (the highest resolution can reach the nanometer level), strong anti-interference ability, no human reading error, convenient device, reliable use and other interests.
Features of the displacement sensor:
1. The function of the linear displacement sensor is to convert the linear mechanical displacement into an electrical signal. In order to achieve this effect, the variable resistance slide rail is usually fixed on the fixed part of the sensor, and the displacement of the slide blade on the slide rail is used to measure different resistance values.
2. The sensor slide is connected to the steady-state DC voltage, which promises to flow through a small current of microamperes, and the voltage between the sliding blade and the beginning is proportional to the length of the sliding blade. The use of the sensor as a voltage divider minimizes the requirement for the accuracy of the total resistance value of the slide, as the change in resistance caused by the change in temperature does not affect the measurement results.
3. Angle displacement sensor is used for obstacle treatment: using angle sensor to control your wheel can directly find obstacles. The principle is very simple: if the motor angle sensor structure is working and the gears are not turning, your machine is now blocked by obstructions.
