RF Capacitive Level Meter Product Details

RF capacitance level meter uses RF capacitance detection technology, supplemented by temperature compensation technology. It also solves the defects that traditional capacitive level gauges are difficult to overcome, such as large temperature drift, poor linearity, and poor resolution. The product has high measurement accuracy, strong anti-interference ability and reliable performance.

Product-specific shell, beautiful appearance, power supply module and electronic transmitter module isolation, with high security. According to different application conditions using different materials, the form of the probe, compact structure, easy installation, can adapt to a variety of harsh environments, RF capacitance level gauge is widely used in continuous measurement of high temperature, high pressure, corrosive medium level. The use of an electrode sensor to measure the liquid level as a function of the capacitance change of the liquid level, the electrode and the container wall made of a metallic material (when the container wall is non-metallic or irregular in shape, the auxiliary electrode or coaxial probe is used) A capacitor. The capacitor formed by two given electrodes (given probe and given container) and the measured medium is excited with a fixed frequency voltage, and flows through the capacitor current when the dielectric constant of the process medium is constant. The size is proportional to the height of the medium between the electrodes. The transmitter's electronics convert this to a 4 to 20 mA standard signal output.
