The SLB70 RF admittance level switch is a point-to-point level switch manufactured based on the principle of RF admittance measurement, and is a replacement product for capacitive level switches. Even under extremely harsh on-site conditions, it can work reliably without being affected by material hanging, pressure, material density, humidity, and changes in material chemical properties.  
Strong usability: widely used in various occasions, including fly ash, particles, powders, liquids, viscous, conductive, and non-conductive materials;  
Anti adhesion: The unique circuit design allows the measurement circuit to ignore the accumulated materials on the probe and automatically correct them;  
Detached probe: The probe and controller can be separated without cable connection, making installation and removal easy and not affecting on-site work;  
Powerful function: Large output contact capacity and status indicator light to display working status, with a delay of 0-30 seconds to eliminate the impact of material fluctuations;
