RF Capacitive Level Transmitter

RF capacitive liquid level transmitters are widely used in the measurement of liquid level and material level in electric power, metallurgy, chemical industry, food and pharmaceutical industries and in sewage treatment boiler steam drums, pulverized coal drums and other places. The product is based on the principle of capacitive induction. When the measured medium is dipped and the height of the measurement electrode changes, its capacitance changes. It can convert the changes in various material levels, liquid levels, medium heights into standard current signals and transmit them remotely to the operation control room for centralized display alarm or automatic control by secondary instruments or computer devices. Its good structure and installation method can be used for high temperature, high pressure, strong corrosion, easy crystallization, anti-clogging and anti-freezing and solid powdery granular materials.
Product Features of RF Capacitive Liquid Level Transmitter
Compact structure, small size, simple installation and maintenance, unified appearance and dimensions.
A variety of signal output forms facilitate different system configurations.
PTFE grade is resistant to acid and alkali and other highly corrosive liquids and high temperatures.
The measurement part immersed in the liquid has only one PTFE soft wire or PTFE rod probe as the sensor, which has high reliability.
Fully sealed aluminum alloy shell and stainless steel connectors.
For high-temperature pressure vessels, it is as simple as measuring normal temperature and pressure, and the measured value is not affected by the temperature specific gravity of the liquid being measured and the shape and pressure of the container.
The two ends of the measurement output and the three-terminal isolator of the measurement output power supply are equipped with various circuit structures and built-in isolators to adapt to different signal grounding methods.
Perfect over-current and over-voltage power supply polarity protection.
