    Capacitive Water Level Sensor, 0-900mm

    ATO capacitive water level sensor adopts the capacitive detection principle and uses a coaxial container and shell to combine the inner and outer electrodes, available in measuring ranges of 0 to 900mm. This non-contact capacitive liquid level switch can be widely used in water conservancy, environmental protection and electric power.

    Tips: Is the capacitive water level sensor susceptible to interference?

    Capacitive water level sensors can be susceptible to interference, although the extent varies depending on the design and environment. Common sources of interference include electromagnetic fields from nearby electrical equipment, stray capacitance from surrounding objects, and changes in temperature or humidity. These interferences can lead to inaccuracies in water level measurements or false readings. Shielding techniques, proper grounding, and signal filtering can help mitigate interference effects to some extent. Additionally, careful placement of the sensor away from sources of electromagnetic interference and calibration procedures can further improve its resistance to disturbances. Despite these measures, it's important to recognize that no sensor is completely immune to interference, and users should consider the specific environmental conditions and potential sources of interference when deploying capacitive water level sensors.
