A32 RF capacitor level transmitter can solve most high temperature, high pressure and corrosive liquid level measurement. It uses the American company's RF capacitor technology and chip and polytetrafluoroethylene as the insulating material. Compared with the double flange liquid level gauge, float type liquid level gauge, isotope type liquid level gauge, it is a simple, durable and convenient instrument.
Measuring principle of RF capacitor level transmitter:
If the probe and the container wall are regarded as two parallel electrode plates, and the measured liquid is regarded as the medium between them, then a simple capacitor is formed. When the liquid level rises, the capacitance increases, and the RF circuit converts this change into an analog signal output. RF capacitor level transmitters are widely used in the measurement of liquid levels of acids, alkalis, chlorides, organic solvents, liquid CO2, ammonia, PVC powder, ash, oil-water interface, traditional Chinese medicine and so on.
1. Compact structure, small size, simple installation and maintenance, and uniform size.
2, a variety of signal output forms, convenient for different system configurations.
3, PTFE detection grade, resistant to strong corrosive liquids such as acid, alkali and high temperature.
4. In the measurement part immersed in liquid, there is only one PTFE flexible wire or PTFE rod probe level as the sensor, which has high reliability.
5. Fully sealed aluminum alloy shell and stainless steel connecting pieces.
6. For high-temperature pressure vessels, it is as simple as measuring room temperature and pressure, and the measured value is not affected by the temperature, specific gravity of the measured liquid, and the shape and pressure of the vessel.
