Product Description
Working Principle
The RF admittance level instrument is developed from the capacitive level measurement technology. It is a level control detection instrument with anti-hanging material, more reliable, more accurate and wider applicability. RF admittance is a combination of resistive, capacitive, and inductive components.
RF admittance level control technology is to achieve level measurement by measuring the admittance of the measured medium with high frequency radio waves. The difference between RF admittance technology and capacitive technology lies in the diversity of measurement quantity and three-electrode technology. A shield electrode is added between the measurement electrode and the ground electrode to protect the halo electrode from the influence of the hanging material, and the measurement is more stable. Accurate and reliable.
When the position of the material changes, the three-electrode signal processing circuit compares the comprehensive change signal of impedance, capacitive reactance and inductive reactance with the reference signal. When the difference between the two signals reaches a certain level, the output state of the relay changes, thereby detecting Level changes.

Features
- Anti-adhesion: unique circuit design and sensor structure can eliminate the influence of the measurement of the material on the probe, and automatically correct it, avoiding false measurements and signals, and no need to clean the probes regularly;
- Maintenance-free: The switch can be moved by mistake, no mechanical wear, no maintenance required;
- Strong anti-interference: contact measurement, 0.3 second delay can eliminate the influence of material fluctuation;
- Strong adaptability: can detect powder, particles, liquid, viscous, conductive, non-conductive materials.
