1. Frequency response characteristics
The frequency response characteristics of the sensor can determine the frequency variation range to be measured. We need to keep the distortion-free measurement technical conditions within the allowable frequency range. In fact, the response of the sensor always has a certain delay, and it is hoped that the delay time is as short as possible.
2. Sensitivity
The selection of the sensor for the electric cylinder is very important. The higher the sensitivity, the more accurate the measurement result, but the higher the sensitivity, the more susceptible it is to interference from external factors. , It is easy to cause measurement accuracy, so when using it, it is necessary to reduce the equipment that interferes with the signal in the working area.
3. Linear range
The linear range of the sensor is the range in which the output is proportional to the input. Theoretically, the sensitivity remains unchanged within this range. The wider the linear range of the sensor, the larger the measurement range, and a certain accuracy can be guaranteed. When selecting a sensor, first determine the type of sensor and whether its measurement range meets the requirements.
4. Accuracy
Accuracy is a very important performance analysis indicator of the sensor, which is mainly related to the measurement accuracy of the measurement control system. Naturally, if the sensor has a higher accuracy, its price will be higher. Therefore, the accuracy of the sensor needs to continuously meet the accuracy requirements of the entire measurement information system of the enterprise, and we do not need to choose too high.
5. Stability
The ability of a sensor to maintain its performance unchanged after a period of work can be called stability. In addition to the sensor technology itself, outside of the structure, it is the main economic factor affecting the performance of the sensor. The long-term stability of the sensor is the network environment in which the sensor is used. Therefore, in order for the sensor data to have good stability, the sensor must have strong adaptability to the environment.
