FAQ Question?What is the main advantage of a vibrating fork level switch like the Liquiphant M?The main advantage is its reliability and lack of moving parts. It is unaffected by the liquid’s properties like conductivity, density, or dielectric constant, making it a versatile and maintenance-free solution. Question?Can this FTL51 sensor be used in hazardous areas?Based on the order code ‘A’ for Approval (Non-hazardous area), this specific model is intended for use in safe, non-explosive environments. For hazardous areas, a model with the appropriate ATEX or FM certification would be required. Question?What does the PNP output mean for installation?A PNP output is a “sourcing” type transistor output. When the switch is activated, it connects the output to the positive supply voltage (V+). This is a common standard for connecting to PLCs and control systems. Ensure your PLC input card is compatible with PNP (sourcing) signals.
