Radio Frequency Admittance Level Transmitter

Shanghai Zhaohui Pressure Apparatus Co., Ltd. is one of the leading manufacturers and suppliers of radio frequency admittance level transmitter in China, also supports customized service and 1 year warranty. Welcome to wholesale bulk durable radio frequency admittance level transmitter in stock here from our factory.

This radio frequency admittance level transmitter employs a probe energized with high-frequency RF voltage to measure the complex impedance (admittance) between the probe and tank wall. Changes in material level alter capacitance and conductance, which are electronically converted to a level reading. Advanced models incorporate active shielding to eliminate cable and coating effects, ensuring reliability with sticky, conductive, or corrosive media. The radio frequency admittance level sensor operates in both liquids and solids, handling extreme temperatures and pressures. The output is unaffected by density or dielectric variations within limits. Typical uses include interface detection, sludge beds, and granular silos, offering robust performance where optical or ultrasonic methods fail due to dust, foam, or buildup.

Sticky slurries, conductive acids, corrosive chemicals, cement silos, fly ash hoppers, plastic pellets, grain bins, and interface detection between oil/water or foam/liquid. The radio frequency admittance level transmitter is preferred in mining, food powders, petrochemical refineries, and power plants where buildup, dust, or harsh conditions disable other sensor types.

Active shielding technology rejects cable capacitance and compensates for probe coating or material buildup. Unaffected by dust, foam, vapors, or changing dielectric constants. Operates reliably in vacuum, high pressure, and extreme temperatures. No moving parts ensure long service life. Handles both conductive and corrosive media, liquids and solids, making it ideal for harsh environments where other sensors fail prematurely.
