  • Bulk | liquid material vibrating level switch | sensor | detector | 40mm | 18-30VDC / 85-250VAC | 5A | SPDT

    Code: ES-LSK311

    Vibrating level switch – a professional, reliable solution for detecting the level of bulk materials (powders, granules) and liquids in industrial tanks, hoppers, or silos. The device operates on the vibration principle, making it resistant to dust, deposits, foam, and changes in material properties. 

  • Technical specifications

    Power supply: 18-30 V DC / 85-250 V AC
    Output signal: Relay 5 A / 250 VAC, SPDT
    Measuring length: 40 mm
    Working pressure: -0,1 MPa … +2,5 MPa
    Operating temperature: -20 °C … +100 °C
    Mechanical connection: Thread, Flange, Clamp
    Minimum detection density limit: Bulk materials: ≥ 0,23 g/cm³; Liquids: ≥ 0,8 g/cm³

    Main features and functions

    Universal application – suitable for both bulk materials and liquids
    Stable operation regardless of density fluctuations
    Relay output (SPDT) – easy integration into automation systems
    Various mechanical connections – thread, flange or clamp

    Application

    For electrician / automation specialist: Fast installation into existing tanks or silos. Easy connection to PLC, relay or signal circuits. Low sensitivity to vibrations and environmental interference.
    For engineer / project manager: Reliable solution for demanding media (dust, granule flow, foam). Low maintenance costs, long service life.
    For food, chemical, pharmaceutical industry: Resistant to aggressive substances. Stable operation even when product properties change.

    Pros

    Works with both powders and liquids
    Does not require calibration for material
    Resistant to dust, deposits and vibrations
    Wide power supply and mounting options

    Cons

    Not suitable for very low density bulk materials (< 0,23 g/cm³)
    This is a level switch (ON/OFF), not a continuous level meter
