    NESOS R03 LS – Float Switch with Reference Vessel (408303)



    • Point level measurement via floats and reed contact
    • High switching voltage (up to 230 V AC/DC) and high switching current (up to 1 A)
    • Large temperature range for mediums from -30 to +150 °C
    • Optionally available with Pt100, Pt1000, or temperature switch
    • Suitable for lateral mounting due to reference vessel
    • Approvals for shipbuilding as well as certificate for Pressure Equipment Directive (PED) available


    Customer benefits


    • Proven, maintenance-free measuring principle – the switching operation takes place without contact or auxiliary energy and is therefore wear-free
    • Customer-specific solutions possible – many materials and forms are available for the float; in-house manufacturing of the float with a high production depth
    • Flexible measurement – point level can be determined independently from the container geometry due to the measuring principle
    • Independent from media properties such as foam formation, conductivity (permittivity (ε)), pressure, vacuum, steam, and condensation
    • Constant, reliable switching point repeat accuracy over the course of the operating life
    • Quick error check when servicing
    • High degree of chemical resistance due to availability of different materials
    • Cost-effective installation and mounting
    • Maintenance-free
    • Price-performance ratio optimized through the use of standard components and processes
