Sensitivity of the proximity sensor
Sensitivity refers to the ratio of the output rate of change of the proximity sensor to the steady-state value in the case of input variation, which is the slope of the input characteristic curve. If the output of the proximity sensor is linear to the input, then the sensitivity is a constant. Otherwise, it will vary with the amount of input.
The magnitude of the sensitivity is the ratio of the output to the input. For example, if a displacement proximity sensor changes by 1 mm and the output voltage changes by 200 mV, its sensitivity should be expressed as 200 mV/mm. When the output proximity sensor is the number of input phases, the sensitivity can be understood as the amplification factor. The increased sensitivity allows for higher measurement accuracy. However, the higher the sensitivity, the narrower the measurement range and the worse the stability.
Proximity to the resolution of the sensor
Resolution refers to the ability of a proximity sensor to be measured with a suitable small variation. That is, if the input changes slowly from a non-zero. When the input value does not exceed a certain value, the output of the proximity sensor does not change, that is, the change in the input quantity of the proximity sensor is not resolved.
When the input changes more than that resolution, the output changes. The resolution of a typical proximity sensor is not the same as that of a full-scale range, so a large change in the input amount that can be produced by the output step change is used as the measurement resolution. If the target above is represented as a percentage of a full range, it is called resolution.
There is a negative correlation between the resolution and stability of the proximity sensor. Shenzhen Intelligent Proximity Sensor Co., Ltd., 15 years of integrity brand, welcome to call.
