NYSP-Z19 RF Admittance Level Transmitter Working Principle
RF conductivity measurement technology is a level measurement technology with unique advantages. Although the concept is similar to that of the general capacitive measurement technology, the RF conductivity technology incorporates a Driving-Shield circuit and a chopper circuit in the electronic unit, thus enabling separate measurement of impedance and capacitive resistance. The impedance and reactance of any pendant are calculated by the laws of physics to be equal in magnitude, so the effect of the pendant can be measured and eliminated from the total output by phase shifting of the oscillator circuit.
The probe of the RF conductivity level meter is installed in the tank and the change in RF signal caused by the change in level is obtained by the probe. The Driving-Shield end of the probe prevents the RF current from forming a loop through the hanging material, ensuring the accuracy of the measurement.
RF conductivity measurement technology is a liquid level measurement technology with unique advantages. Although the concept is similar to the general capacitance measurement technique, the RF conductivity technique incorporates a driver shield circuit and a chopper circuit in the electronic unit, so impedance and capacitance resistance can be measured separately. The impedance and reactance of any hanger are calculated according to the laws of physics and are equal in magnitude, so the effect of the hanger can be measured and removed from the total output by the phase shift of the oscillator circuit.
The probe of the radio frequency conductivity liquid level meter is installed in the storage tank, and the radio frequency signal change caused by the liquid level change is obtained through the probe. The probe's driven shield prevents RF current from looping through the suspended material, ensuring accurate measurements.
1. Anti-hanging material: The unique drive shielding circuit design improves the performance of the anti-hanging material.
2. Power supply range: power supply operating range: 13 ~ 35VDC.
3. Adaptability: Probe process temperature: -100 ℃ ~ 800 ℃; no dead zone measurement, can be used in horizontal measurement occasions of more than ten centimeters or even a few centimeters, with a large measurement range;the maximum measurement range of up to hundreds of meters, or even hundreds of meters; viscous material interface measurement is the great advantage of the instrument.
4. Stability: The output is stable and reliable, and it is resistant to the influence of fly ash, blanking, water vapor,
crystallization and waxing.
5. Maintenance-free: no moving, no easy-to-wear parts, no need for frequent cleaning, maintenance, commissioning.
