The P100 radio frequency admittance level switch adopts the most advanced NULL-KOTE anti-adhesion electronic circuit of the United States, which can detect the real level while eliminating fake signals that are stuck and hung around the probe.
2. Product principle:
The P100 series radio frequency admittance level switch is a replacement product of the capacitive level switch, which solves the problem of material adhesion and has higher system stability than other similar products. Even under extremely harsh site conditions, it can work reliably without being affected by changes in material hanging, temperature, pressure, material density, humidity, and even material chemical properties.
Three, measurement principle
Radio frequency admittance level meter is a kind of level control technology developed from capacitive level measurement technology, which is anti-hanging, more reliable, more accurate, and more applicable. The meaning of admittance in radio frequency admittance is The reciprocal of impedance in electricity is composed of resistive, capacitive, and inductive components. The radio frequency emits high frequency radio waves, so the radio frequency admittance level control technology realizes the level measurement by measuring the admittance of the measured medium with high frequency radio waves. The most important difference between RF admittance technology and capacitive technology is the diversification of the measurement volume and the three-electrode technology. The diversification of radio frequency admittance measurement lies in not only measuring capacitance, but also resistance and inductance, which makes the measurement more accurate. The three-electrode technology includes electronic units and sensors. A shielding electrode is added between the measuring electrode and the ground electrode to protect the measuring electrode from hanging materials.
