This level sensor features low power use and flexible voltage options, making it easy to integrate into different systems. It is widely used in various types of silos, containers, and pipelines for empty and full material measurement.

    Feature

    • The RF admittance type level switch features a completely enclosed, integrated construction with built-in digital electronics and no moving components. Once installed, the zero point can be set a single time without repeated adjustments.
    • Its digital circuitry minimizes the effects of temperature and humidity changes, eliminating the need for seasonal zero-point recalibration. The optimized design helps avoid false triggers from material buildup on the probe and maintains stability under varying process conditions.
    • This type of level sensor performs reliably in harsh environments such as extreme heat, high pressure, heavy dust, and sticky media, providing precise level detection for both solids and liquids.
    • With a straightforward digital zero-setting process, users can complete initial calibration quickly, reducing setup complexity and boosting operational efficiency.

    FAQ

    An RF admittance level switch determines the liquid level by measuring the capacitance change between the sensor electrodes and the measured medium. When the medium contacts the electrodes, the capacitance change triggers the switch to operate, thus detecting the liquid level.

    RF admittance level sensors are suitable for liquids, slurries, and certain powdered solids, especially for media environments with high foam, high viscosity, or conductivity. However, dry powders and non-conductive liquids may require special models.

    During installation, avoid direct contact between the sensor and container walls, agitators, or pipes to prevent malfunction. The sensor should be installed vertically, and the appropriate length and material should be selected according to the properties of the medium.
