使用寿命：电位传感器的使用寿命长达1亿次行程；磁伸缩位移传感器由于与游标之间无接触，因此在实际应用中其寿命是无限长的。 ， 电阻轨道长度：150mm,光电传感器是采用光电元件作为检测元件的传感器。它首先把被测量的变化转换成光信号的变化，然后借助光电元件进一步将光信号转换成电信号。光电传感器一般由光源、光学通路和光电元件三部分组成。，,随着对测量精度要求的提高，以栅距为单位已不能满足要求，需要采取适当的措施对莫尔条纹进行细分。所谓细分就是在莫尔条纹信号变化一个周期内，发出若干个脉冲，以减少脉冲当量。如一个周期内发出n个脉冲，则可使测量精度提高n备，而每个脉冲相当于原来栅距的1/n。由于细分后计数脉冲频率提高了 n倍，因此也称n倍频。， 测试结果：线性率0.058%六、光电池在光电检测和自动控制方面的应用，,光通讯， 电阻导轨是传感器中重要的部分，采用导电塑料覆盖在基材上，具有良好的耐磨特性。欧牧采用精密修刻设备将导电塑料轨道修刻到所要求的线性度。,光电传感器分类Brief introduction of sensor The rapid development of Control Engineering (the electronic control system of progress, resulting in a massive demand on the sensor, the sensor industry require the use of superior performance, low price, can be in harsh environments (e.g. -40 to 150 degrees Celsius) to work under the performance parameters of this er mainly expounds the conductive plastic sensor for measuring angles and lines the movement of the. The position sensor mainly includes the following parts: 1 A, resistance (auxiliary material + conductive plastic resistance track) The resistance rail is the most important part of the sensor, which is covered with conductive plastic on the substrate, and has good wear resistance. The European Union uses the professional precision trimming equipment to engrave the conductive plastic track to the required linearity. One B, brush (precious l alloy) The brush is a decisive element in the sensor, it is the precious l support, the shock structure design, long service life (one hundred million), low starting torque, high speed operation (10m/s) C, transmission shaft or joystick D, connecting bearings E, shell The shell material is aluminum. After anodic oxidation, the structure is strong and corrosion resistance is strong Trip L1 defines the electrical stroke. L2 shows the continuous stroke, which also includes the nonlinear connection region. L3 represents the total electrical stroke. L4 represents mechanical travel. There are still some unused parts that cannot be included in the overall itinerary. Independent linear If the brush moves in one direction, the output voltage and the mechanical input value of the potentiometer will be shown in figure 3. The ratio of the actual curve distance to the ideal linear maximum deviation to the full range of the sensor is called the independent linear error. Error + F is the deviation between the output voltage calculated by the percentage and the theoretical input voltage. The measured samples are shown in figure 4. Today, the typical values of independent linear rates are between 0.2% and 0.02%. Potentiometer linearity test result Test conditions: room temperature 26, humidity 52% Resistance track length: 150mm Test result: linearity rate is 0.058% Absolute linearity (absolute linear becomes more and more valuable, it is not absolutely independent linear, linear reference boundary has restricted well, the need for system tuning. Absolute standard by a linear index, established a mechanical input (or stroke) and the relationship between the output voltage of the potentiometer, because the reference point is determined according to the actual situation, so it is more suitable for industrial process control. The absolute linearity requires the output value to be within the tolerance range specified in the diagram contact resistance The contact is the resistance between the terminal of the brush and the direct contact point of the brush at the resistance track of the potentiometer. Contact resistance is an important index to affect the performance of potentiometer. The contact resistance consists of three parts: The first part is the overall voltage drop between the current carrying resistor track and the contact surface. This part depends largely on processing factors, about a few hundred ohms. The second part, the external component, is much harder to control than the first. This external transition resistance is very similar to the contact resistance that occurs between switches and plug and socket connectors. From an electrical point of view, this is due to the excessive contact between the brush and potentiometer resistance track. Metal oxides, chlorides and sulfides, mixed with various organic substances, lead to a thin of insulation on the resistive rail surface. If it is not guaranteed to be within a certain range, these additional resistances will lead to a complete tolerance beyond the tolerance range under adverse conditions. It is absolutely necessary to ensure the strict quality control and ensure the matching of the potentiometer in the manufacturing process. In the third part, the dynamic part is related to the high speed motion of the brush under the action of the driving force. With the aid of damping brush, it is not possible to increase any resistance at a speed of 10 meters per second. The cause of linear error There are two main reasons for linear error: For example, by a circuit caused by the weak, when the current through the brush when the contact resistance exists, similar to the ohmic load, for example: when the work through the current brush by 1 A increased to 10 A, accuracy loss of 1%, smaller values of contact resistance the linearity, the impact is small, the working current is small, the linearity of the impact is small. Two, because the mechanical connection is caused, if there is axial dislocation (eccentricity), then between the driver and the potentiometer movement there is an angle, which will lead to linear error. Output smoothness Smoothness is an index to measure the deviation of the output voltage of the potentiometer. This index is usually represented by the ratio of the applied voltage to the applied voltage over the specified stroke increments, for example, by the percentage of applied voltage. The output smoothness is affected by contact resistance, resolution, and other nonlinear factors. Resolving power The output sensitivity is used to measure the potentiometer resolution, it mainly depends on the detection principle of resistance type position sensor resolution is infinitely small, so any slight movement can be detected. Repeatability accuracy When the sensor is running repeatedly, the output value is different at the same mechanical position every time. The maximum difference between these output values is the repeatability accuracy. Repeatability is mainly affected by temperature, humidity, mechanical connection and other factors.

第三部分，动态部分，和电刷在驱动力的作用下高速运动有关。借助于阻尼电刷，才能实现在传动速度达10米/秒的时候不明显的增加任何电阻。，通常用的有两种细分方法：其一：直接细分。在相差1/4莫尔条纹间距的位置上安放两个光电元件，可得到两个相位差90o的电信号，用反相器反相后就得到四个依次相差90o的交流信号。同样，在两莫尔条纹间放置四个依次相距1/4条纹间距的光电元件，也可获得四个相位差90o的交流信号，实现四倍频细分。其二：电路细分。，光电池作为光电探测使用时，其基本原理与光敏二极管相同，但它们的基本结构和制造工艺不完全相同。由于光电池工作时不需要外加电压；光电转换效率高，光谱范围宽，频率特性好，噪声低等，它已广泛地用于光电读出、光电耦合、光栅测距、激光准直、电影还音、紫外光监视器和燃气轮机的熄火保护装置等。
