Application of displacement sensor
This kind of sensor is widely used in different fields, such as automobile, medical equipment, robotics, wood processing machine, molding machine
Important parameters include:
1.Accuracy and linearity of requirements
2. Expected range
3. Repeatability / resolution
4. Required torque (low)
5. Environment, vibration, dust temperature and humidity
6. Electrical travel
7. Required speed and expected price and life
电子尺（又称直线位移传感器，电阻尺），适用于注塑机，木工机械，印刷机，喷涂，机床，机器人，工程监测电脑控制运动器械等需要精确测量位移的场合。
Conductive plastic potentiometer (voltage divider, electronic ruler) available in late 50s, and is widely used in automobile, injection molding machine, wood processing machine and modern different industries. Sensor prices are relatively cheap, low temperature change, low torque operation and high-speed applications are unique features of conductive plastics technology.
