[0023] It can be understood that the rotation speed of an object can be measured through the sensing component 21, the sensor body 1 can be fixed through the fixing component 31, the design of the elbow 4 enables the sensor body 1 to flexibly adapt to various installation environments, and is connected to the sensor body 1 and external measuring equipment through the connecting component 51 for transmitting signals.

[0024] Specifically, when it is necessary to measure the rotational speed of an object, first connect the sensor body 1 and the external measuring equipment through the connecting component 51 to transmit signals. The sensor body 1 can be fixed by the fixing component 31. The design of the elbow 4 enables the sensor body 1 to flexibly adapt to various installation environments. The rotational speed of the object can be measured through the sensing component 21, and the obtained data is transmitted to the external display device through the connecting component 51.

[0025] In one embodiment of the present invention, Figure 3As shown, the sensor assembly 21 includes a transmitter 211 and a receiver 212 , wherein a groove 11 is provided at one end of the sensor body 1 , the transmitter 211 is provided on one side of the groove 11 , and the receiver 212 is provided on the other side of the groove 11 .

[0026] It is understood that the transmitter 211 is used to transmit electromagnetic waves of a specific frequency to illuminate the surface of the rotating object, and the receiver 212 is located at a relative position to the transmitter 211 to receive the electromagnetic waves reflected from the surface of the rotating object.

[0027] In one embodiment of the present invention, Figure 3 As shown, the fixing assembly 31 includes a fixing nut 311 and a fixing bracket 312, wherein the fixing nut 311 is arranged on the sensor body 1, and the fixing nut 311 is threadedly connected to the outer surface of the sensor body 1 respectively, and the fixing bracket 312 is arranged on the sensor body 1, and the fixing bracket 312 is located between the fixing nuts 311.

[0028] It can be understood that the fixing nut 311 is used to fix the sensor body 1 on the fixing bracket 312 to ensure the stability and reliability of the sensor during the measurement process. The fixing bracket 312 is easy to install and disassemble. The bracket is provided with an installation direction mark to indicate the correct installation direction of the sensor to ensure the accuracy of the measurement result.

[0029] In one embodiment of the present invention, Figure 1 As shown, the connecting component 51 includes a wire hole 511, a cable 512, a cable sheath 513 and an annular pattern 514, wherein the wire hole 511 is arranged at one end of the elbow 4, the cable 512 passes through the wire hole 511 and is connected to the circuit inside the sensor body 1, the cable sheath 513 is wrapped around the outside of the cable 512, the annular pattern 514 is located on the surface of the cable sheath 513, one end of the cable 512 is connected to the circuit of the sensor body 1, and the other end is connected to an external measuring device.
