What is an RF admittance level switch and how does it work?
An RF admittance level switch measures both capacitance and resistance (impedance) between the probe and material. It uses this combined signal to accurately detect material level, even in the presence of buildup or coating.
What is the advantage of RF admittance over capacitive level switches?
A RF admittance level switch for anti-buildup applications can distinguish between actual material and coating buildup, while traditional capacitive switches often produce false signals due to adhesion.
Can RF admittance level switches handle sticky or viscous materials?
Yes, this RF admittance level switch for sticky materials is specifically designed to handle:
- Slurry
- Fly ash
- Viscous liquids
- Adhesive powders
Does the RF admittance level switch require calibration?
No complex calibration is required. The intelligent RF admittance level switch can automatically adjust its working range and simplify setup using its built-in LCD interface.
Is the RF admittance level switch suitable for harsh industrial environments?
Yes, this industrial RF admittance level switch operates reliably under:
- High temperature
- Dust and moisture
- Material buildup
- Harsh process conditions
What industries use RF admittance level switches?
A RF admittance level switch for industrial use is widely applied in:
- Cement and mining
- Chemical processing
- Food and grain storage
- Power plants (fly ash handling)
