High Reliability RF Capacitance Level Gauge
The working Principle of High Reliability RF Capacitance Level Gauge
It can be used for the crossive liquid, the principle is that, it Applied a radio frequency to probe to determine impact of the surrounding. When air (dielectric constant is 1.0) is replaced by any other material (dielectric constant > 1.0), the change of capacitance value causes the change of impedance. This effect is measured by the circuit and then compared with the reference established by the sensitivity setting (circuit).
Design features of High Reliability RF Capacitance Level Gauge
◎ the modular converter is integrated with the sensor, with no moving parts, high reliability and strong anti-interference ability
◎ more widely applicable, with multiple probe forms, multiple process connection forms, and multiple manufacturing materials, which can be customized;
◎ installation, debugging and maintenance are extremely convenient
