The radio frequency admittance level gauge is an advanced technology developed from capacitive level measurement. It offers improved reliability, accuracy, and versatility, and is designed to address issues like material build-up and temperature drift.
In this technology, "admittance" refers to the reciprocal of impedance, which includes resistive, capacitive, and inductive components. "Radio frequency" denotes high-frequency radio waves used to measure this admittance.
Unlike traditional capacitive methods, radio frequency admittance technology measures various parameters, overcoming challenges such as cable shielding and material accumulation at the sensor base. This versatility makes it suitable for a wide range of applications.
During operation, the sensor measures the admittance between the sensor, vessel wall, and the medium. As the liquid level changes, the admittance value changes correspondingly, and this value is converted into a level signal for accurate measurement.
Product Features:
Advanced Circuit Design: The unique circuit design allows the measurement circuit to be automatically corrected for any accumulation of material in the probe, ensuring
accurate measurements without interference.
Wireless design: No cable connections, which facilitates installation and removal, allowing for hassle-free installation and minimal disruption
to operations.
RF and Digital Technology: The incorporation of RF (Radio Frequency) and digital technology significantly improves system reliability and
performance, ensuring stable and accurate measurements.
