Product Introduction:

Factors affecting the main static parameters of capacitive liquid level sensors：

1. Dielectric constant of the medium
The dielectric constant of the medium is one of the important factors affecting the main static parameters of the capacitive liquid level sensor. A medium with a larger dielectric constant can improve the sensitivity of the liquid level sensor and make its measurement range wider. When a level sensor is used for a liquid with a small dielectric constant, its sensitivity will be reduced and the measurement range will be limited.

2, the shape, distance and structural material of the electrode
Electrode shape, distance and structural material also affect the main static parameters of capacitive liquid level sensors. In general, the more the shape of the electrode is suitable for the surface shape of the liquid to be measured, the more it can improve the sensitivity of the sensor. In addition, the distance between the electrodes will also affect the measurement range and sensitivity of the sensor, the sensor sensitivity is low when the electrode distance is large, and the sensitivity will be improved. The structural material of the electrode will also affect the stability and service life of the sensor.

3. Ambient temperature and humidity
The ambient temperature and humidity of a capacitive level sensor also affect its main static parameters. As the temperature rises, the sensitivity of the capacitive sensor will decrease, affecting the measurement accuracy. The use of capacitive sensors in high humidity environments may cause the medium between electrodes to become more conductive, affecting the sensitivity and stability of the sensor.

4, external electromagnetic interference
External electromagnetic interference is also one of the main factors affecting the static parameters of capacitive liquid level sensors. When the capacitive sensor is interfered by the external electromagnetic field, the sensitivity and stability of the sensor will be affected, and the measurement accuracy will be affected.

In summary, there are many factors that affect the main static parameters of capacitive liquid level sensors, including the dielectric constant of the medium, the shape of the electrode, the distance and structural materials, the ambient temperature and humidity, and external electromagnetic interference. In practical applications, it is necessary to select and adjust according to the specific situation to ensure the normal use and accurate measurement of the sensor.
