- AO8010 Radio Frequency Admittance Level Meter
◆Measurement principleThe product evolved from capacitive level measurement technology and employs a three-terminal technique to ensure more reliable measurements. The term "admittance" in "radio frequency admittance" refers to the reciprocal of impedance in electrical engineering, while "radio frequency" denotes high frequency. Therefore, this product is an instrument that measures admittance using high-frequency current.Tri-terminal technology utilizes the coaxial cable shielding layer suspended within a very small yet stable amplitude range. Since it maintains equal potential, same phase, and identical frequency with the measured signal—yet without direct electrical connection—it forms an equivalent scenario of "zero" capacitance,thereby enhancing measurement stability.◆Main characteristics
▶Liquids: conductive liquids and insulating liquids;▶Particles: grains, plastic flakes, coal, etc.;▶Interface: Boundary between media with different dielectric constants andtwo types of liquids;▶Powder: plastic powder, cement, fly ash, etc.;▶Maintenance-free: No mechanical components, not prone to clogging,breaking, or damage;▶Anti-hanging material ;▶Temperature range: -183~815 degrees;▶Pressure: 0~10MPa;▶Built-in 1000V spark protection.◆Application ScenariosDesigned for real-time monitoring of powder, granular, and liquid levels in containers suchas hoppers, silos, and storage tanks. It achieves indirect measurement of material height andapproximate weight calculation by directly measuring the empty space distance from the top.This equipment is suitable for various working conditions, particularly ideal for levelmeasurement in heavy dust environments. It overcomes the critical limitations of ultrasoniclevel meters being unable to penetrate dense dust and radar level meters suffering fromantenna base dust accumulation, making it the optimal choice for heavy dust measurementscenarios. RF admittance level gauges are widely applied in harsh environments includingPVC powder silos, cement storage bins, power plant ash silos, and flour bulk storage silos. -
