Working principle of the Rf Admittance Level Transmitter
The radio frequency admittance level meter is a continuous level measurement product based on the principle of radio frequency admittance. The product has the advantages of high stability, high sensitivity and wide application. Compared with the traditional capacitive level meter, it adopts modular design, which can realize simple and convenient instrument setting. Once the setting is completed, it can be used normally and maintenance-free for life. It enables users to intuitively understand the operation of the equipment and deal with the problems in time. It is also safe and reliable in complex industrial occasions.
Design Features of the Rf Admittance Level Transmitter
◎Anti-hanging material Unique Driving-Shield circuit design improves Anti-hanging ability
◎Power supply Power supply working range: 13~35VDC
◎Adaptability Probe process temperature: -100℃~800℃
No dead zone measurement. It can be applied to the level measurement occasions of ten centimeters or even a few centimeters.
Large range, the maximum measurement range can reach hundreds of meters or even hundreds of meters.
The interface measurement of viscous materials is a huge advantage of this instrument
◎Stability Stable and reliable output, resistant to fly ash, blanking, water vapor, crystallization, wax deposition
◎Maintenance free No moving, no wear parts, no need for frequent cleaning, no need for constant maintenance and debugging
