总结电容式传感器优势5大优势

1.高阻抗，小功率

克特电容式传感器因带电极板 间静电引力极小(约几个10-5 N)，因此所需输入能量极小，所以特别适宜用来解决输入能量低的 测量问题，例如测量极低的压力、力和很小的加速度、位移等，可以做得很灵敏,分辨力非常髙，能 感受0.001μm甚至更小的位移。

2.温度稳定性好

克特电容式传感器的电容值一般与电极材料无关，有利于选择温度系数低的材料， 又因本身发热极小，对稳定性影响甚微。

3.结构简单，适应性强

电容式传感器的待测体是导体或半导体均可,可在恶劣环境中工作。电容式传感 器结构简单,易于制造,可做得非常小巧，以实现某些特殊的测量;能工作在高低温、强辐射及强 磁场等恶劣的环境中，也能对带有磁性的工件进行测量。

4.动态响应好

克特电容式传感器由于极板间的静电引力很小，可动部分做得很小很薄，因此其固有频率很 高，动态响应时间短，能在几兆赫的频率下工作，特别适合动态测量，如测量振动、瞬时压力等。

5.可以实现非接触测量，具有平均效应

例如非接触测量回转轴的振动或偏心、小型滚珠 轴承的径向间隙等。当采用非接触测量时,电容式传感器具有平均效应，可以减小工作表面粗糙等对测量的影响

1. High impedance, low power

KTGEE capacitive sensors require very little input energy due to the extremely small electrostatic attraction between electrode plates (about several 10-5 N), making them particularly suitable for solving measurement problems with low input energy, such as measuring extremely low pressure, force, and very small acceleration, displacement, etc. They can be very sensitive, have very high resolution, and can sense 0.001 μ M or even smaller displacement.

2. Good temperature stability

The capacitance value of a Kurt capacitive sensor is generally independent of the electrode material, which is beneficial for selecting materials with low temperature coefficients. However, due to its minimal heat generation, it has little impact on stability.

3. Simple structure and strong adaptability

The test body of capacitive sensors can be either a conductor or a semiconductor, and can work in harsh environments. Capacitive sensors have a simple structure, are easy to manufacture, and can be made very compact to achieve certain special measurements; Can work in harsh environments such as high and low temperatures, strong radiation, and strong magnetic fields, and can also measure magnetic workpieces.

4. Good dynamic response

Due to the small electrostatic attraction between the electrode plates, the movable part of the Kurt capacitive sensor is made very small and thin. Therefore, its natural frequency is high, the dynamic response time is short, and it can work at frequencies of several megahertz. It is particularly suitable for dynamic measurement, such as measuring vibration, instantaneous pressure, etc.

5. Can achieve non-contact measurement with average effect

For example, non-contact measurement of vibration or eccentricity of rotating shafts, radial clearance of small ball bearings, etc. When non-contact measurement is used, capacitive sensors have an average effect, which can reduce the impact of working surface roughness on measurement
