Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a non-contact speed measurement sensor. Background Art

[0002] Traditional speed measurement sensors mainly rely on contact measurement methods, which usually require the sensor or contact head to be directly mounted on the rotating object. Although this method may be effective in some application scenarios, it also brings a series of problems and challenges.

[0003] First, contact measurement is prone to wear and friction. As the rotating object continues to rotate, the contact surface between the sensor or contact head and the rotating part will continue to be rubbed and worn, which not only affects the accuracy of the measurement, but may also shorten the service life of the sensor.

[0004] Secondly, installation difficulties are also a major problem of contact measurement. Installing sensors or contact heads on high-speed rotating objects requires precise positioning and fixing, which not only increases the complexity of installation, but may also lead to improper installation and affect the measurement effect. In addition, for some rotating parts that are difficult to access or have limited space, contact measurement may not be possible at all.

[0005] More importantly, high-speed rotation may cause the sensor or contact head to be subjected to huge centrifugal force, thereby increasing the risk of wear and damage. At the same time, harsh environments (such as high temperature, high humidity, high pollution, etc.) may have an adverse effect on the material properties of the sensor or contact head, resulting in reduced measurement accuracy or sensor failure.

[0025] Specifically, when non-contact measurement of the rotational speed of an object is required, the lead wire 4 is first connected to the sensor body 2 and the signal processing device for transmitting signals. The sensor body 2 can be fixed by the fixing component 31 to ensure the stability and reliability of the sensor body 2 during the measurement process. The rotational speed of the object can be non-contact measured by the sensing component 11, and the obtained data is transmitted to the signal processing device and the external display device through the lead wire 4.

The receiver 112 is located at a relative position to the transmitter 111 and is used to receive the electromagnetic waves reflected from the surface of the rotating object. When the rotating object rotates, the frequency of the electromagnetic waves reflected from its surface will change. The received signal is transmitted to the signal processing device and the external display device through the lead wire 4. By detecting this frequency change, the rotation speed of the rotating object can be calculated.

[0030] Specifically, in the actual implementation process, the sensor body 2 is first fixed to the mounting bracket 312 by the fixing nut 311, which can ensure the stability and reliability of the sensor during the measurement process. The mounting bracket 312 is made of lightweight material, has a compact structure, and is easy to install and disassemble. An installation direction mark is provided on the bracket to indicate the correct installation direction of the sensor to ensure the accuracy of the measurement result.
