XTD-SD-JCK9速度傳感器是一種將非電量（如速度、壓力）的變化轉變為電量變化的原件，根據轉換的非電量不同可分為壓力傳感器、速度傳感器、溫度傳感器等，是進行測量、控制儀器及設備的零件、附件、質保一年

工作原理

盤隨膠帶運行而旋轉時，傳感器的磁感應信號輸入到控制電路中去，經放大、整形后進行計數。其計數值與預置數比較，判斷膠帶機的帶速，即：正常速度、打滑或超速等。同時，執行電路輸出相應的開關信號。

velocity

在機器人自動化技術中，旋轉運動速度測量較多，而且直線運動速度也經常通過旋轉速度間接測量。例如:測速發電機可以將旋轉速度轉變成電信號，就是一種速度傳感器。測速機要求輸出電壓與轉速間保持線性關系，并要求輸出電壓陡度大，時間及溫度穩定性好。測速機一般可分為直流式和交流式兩種。直流式測速機的勵磁方式可分為他勵式和永磁式兩種，電樞結構有帶槽的、空心的、盤式印刷電路等形式，其中帶槽式zui為常用。

折疊激光測速

隨著現今精密制造業的崛起和節省成本的需求，非接觸測速傳感器會慢慢取代接觸式測速傳感器。而現在市場上精度較、zui常用的非接觸激光測速傳感器就是ZLS-Px像差測速傳感器。像差測速傳感器有兩個端口:一個發射端口，發出LED光源;一個是速拍照端口，實現CCD面積速成像對比，通過在極短時間內的兩個時間的圖像對比，分辨被測物體移動的距離，結合傳感器內部的算法，實時輸出被測物體的速度。如圖所示，①LED光發射口，②攝像接收口，③、④接線端，⑤固定螺孔 。①LED光發射口對著被測物發射出激光，經反射到②攝像接收口，接收到信號后傳給信號處理器，通過算法計算出它的速度。

特征

旋轉式速度傳感器按安裝形式分為接觸式和非接觸式兩類。

折疊接觸式

接觸式旋轉式速度傳感器與運動物體直接接觸。當運動物體與旋轉式速度傳感器接觸時，摩擦力帶動傳感器的滾輪轉動。裝在滾輪上的轉動脈沖傳感器，發送出一連串的脈沖。每個脈沖代表著一定的距離值，從而就能測出線速度。

接觸式旋轉速度傳感器結構簡單，使用方便。但是接觸滾輪的直徑是與運動物體始終接觸著，滾輪的外周將磨損，從而影響滾輪的周長。而脈沖數對每個傳感器又是固定的。影響傳感器的測量精度。要提測量精度必須在二次儀表中增加補償電路。另外接觸式難免產生滑差，滑差的存在也將影響測量的正確性。速度傳感器

折疊非接觸式

非接觸式旋轉式速度傳感器與運動物體無直接接觸，非接觸式測量原理很多，以下僅介紹兩點，供參考。

[1].光電流速傳感器

葉輪的葉片邊緣貼有反射膜，流體流動時帶動葉輪旋轉，葉輪每轉動一周光纖傳輸反光一次，產生一個電脈沖信號?？捎蓹z測到的脈沖數，計算出流速。

[2].光電風速傳感器

風帶動風速計旋轉，經齒輪傳動后帶動凸輪成比例旋轉。光纖被凸輪輪盤遮斷形成一串光脈沖，經光電管轉換成定信號，經計算可檢測出風速。

非接觸式旋轉速度傳感器壽命長，無需增加補償電路。但脈沖當量不是距離整數倍，因此速度運算相對比較速度傳感器復雜。

旋轉式速度傳感器的性能可歸納如下:

(1).傳感器的輸出信號為脈沖信號，其穩定性比較好，不易受外部噪聲干擾，對測量電路無特殊要求。

(2).結構比較簡單，成本低，性能穩定可靠。功能齊全的微機芯片，使運算變換系數易于獲得，故速度傳感器應用極為普遍。

XTD - SD - JCK9 speed sensor using circular tube type waterproof structure, has the advantages of waterproof, dustproof, prevent oil pollution can work reliably in harsh environment, is an advand speed sensor, especially suitable for industrial control and military project.
XTD - SD - JCK9 will speed sensor is a kind of non-electricity (such as speed, pressure) into power changes of the original, according to the transformation of non-electricity can be divided into different pressure sensor, speed sensor, temperature sensor, etc., are parts of measurement, control instruments and equipment and acssories. Speed sensor gsc6-sc, warranty year.
The working principle of
When the disk is rotating with the tape, the sensor's magnetic induction signal is input into the control circuit, which is counted by amplification and shaping. Compared with the preset number, it can judge the belt speed of the tape machine, namely: normal speed, skidding or speeding. At the same time, the execution circuit output corresponding switch signal.
When touch wheel rotates with adhesive tape machine running with motivation within the pulse, the pulse when rotating magnetic induction signal caused by the change of the input to the control circuit of speed sensor, after amplification circuit, comparn, plastic to count. Compared with the preset number, the speed of tape is judged and the corresponding switch signal is output. Not only: when the output is lower than the speed of sliding, the circuit output corresponding switch signal, so that the host machine stops. This switch can adjust the speed value.
velocity
In the robot automation technology, the rotation speed is measured more, and the linear motion speed is also measured indirectly through the rotation speed. For example, a speed generator can turn a rotational speed into an electrical signal, which is a speed sensor. The speed measuring machine requires a linear relationship between the output voltage and the speed, and requires the output voltage to be large, and the time and temperature stability is good. The speed measuring machine can be divided into direct flow and ac type. The excitation mode of dc speed measuring machine can be divided into two kinds: he excited type and permanent magnet type, the armature structure has the form of groove, hollow and disc type printing circuit, among which the groove type is the most commonly used.
Folding laser speed measurement.
With the rise of precision manufacturing and the need for cost savings, non-contact speed sensors will gradually repla contact speed sensors. Now, the high precision and most commonly used non-contact laser speed sensor is zls-px aberration speed sensor. The aberration speed sensor has two ports: a transmitting port, emitting LED light sour; Is a high speed photograph port, realize the high speed CCD area image contrast, through the two time in a very short time of image contrast, distinguish the distan of the moving object to be tested, combined with the algorithm of sensor inside, real-time output of the speed of the object to be tested. As shown in the figure, the LED light emitting port, the camera reiving port, the connection end, and the fixed screw hole. The LED light emitting port emits a laser to the measured object, and it is reflected to the camera reiving port. The signal is transmitted to the signal prossor after reiving the signal, and the speed is calculated by the algorithm.
Characteristics of the
The rotary speed sensor is divided into two types: contact and non-contact.
Folded contact.
The contact rotary speed sensor is in direct contact with the moving object. When the moving object is in contact with the rotary speed sensor, the friction fors the roller rotation of the sensor. A rotating pulse sensor mounted on a roller sends a series of pulses. Each pulse represents a rtain distan, so that the linear velocity can be measured.
The contact rotation speed sensor is simple in structure and easy to use. However, the diameter of the contact roller is always in contact with the moving object, and the outer circumferen of the roller will wear out, thus affecting the circumferen of the roller. The pulse number is fixed for each sensor. The measurement accuracy of the sensor is affected. To improve the measurement accuracy, the compensation circuit must be added in the secondary instrument. In addition, it is hard to avoid slip differen, and the existen of slip differen will affect the accuracy of measurement. Speed sensor
Folded contactless.
The non-contact rotary speed sensor has no direct contact with the moving object, and the non-contact measurement principle is very much. The following are only two points for referen.
[1]. Photoelectric velocity sensor.
The blade edge of the impeller is attached to the reflective film, and the impeller is rotated during the flow of the fluid, and the impeller turns a reflection on every week, producing an electrical impulse signal. The flow rate can be calculated by the number of pulses detected.
[2]. Photoelectric wind speed sensor.
The wind drives the anemometer to rotate, and the CAM is rotated in proportion after the gear drive. A series of optical pulses are formed by blocking the optical fiber, which is converted into a fixed signal by the photoelectric tube, and the wind speed can be detected by calculation.
The non-contact rotating speed sensor has long life and no need to increase the compensation circuit. But the pulse equivalent is not an integer multiple, so the speed operation is more complex than the speed sensor.
The performan of rotary speed sensor can be summarized as follows:
(1). The output signal of the sensor is the pulse signal, and its stability is relatively good. It is not easy to be interfered by external noise, and there is no special requirement for the measuring circuit.
(2) simple structure, low cost and reliable performan. Fully functional microcomputer chip makes operation transform coefficient easy to obtain, so speed sensor application is very common.
