Reliable Instruments. Solutions That Fit Your Application.

Instrava is focused on delivering reliable industrial solutions through carefully curated products, application-driven optimization, and flexible customization. We select proven instruments from trusted manufacturers to ensure consistent quality, optimize solutions based on real working conditions to solve practical challenges, and provide tailored configurations to meet specific application needs.

By combining selection expertise with application understanding, Instrava helps customers reduce risk, improve efficiency, and achieve dependable results in complex industrial environments.

symbolizing trust and the beginning of a long-term partnership

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.

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.

Yes, this RF admittance level switch for sticky materials is specifically designed to handle:

  • Slurry
  • Fly ash
  • Viscous liquids
  • Adhesive powders

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.

Yes, this industrial RF admittance level switch operates reliably under:

  • High temperature
  • Dust and moisture
  • Material buildup
  • Harsh process conditions

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)
