    Industrial Capacitive Water Level Sensor, 4-20mA/RS485

    5 out of 5 based on 1 reviews | Write a review
    $326.53
    Industrial 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. Capacitive water level sensor is easy to install and use, with signal output of 4~20mA, 0~5VDC, RS485 or RS232. This capacitive type 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.

    Existing reviews of Industrial Capacitive Water Level Sensor, 4-20mA/RS485
    High sensitivity
    This capacitive water level sensor has high measurement sensitivity, can accurately detect liquid level changes, and has a fast response speed without delay. The non-contact design avoids liquid corrosion to the sensor and requires almost no maintenance. The sensor signal output is stable and can maintain accurate measurement even in environments with large changes in temperature or humidity.
