[Chemical Knowledge]：Working Principle and Application of Capacitive Level Gauge

Read： 270 Time：20months ago Source：Transform the World with Simplicity

Capacitive level gauge is a device widely used in liquid level measurement. It can accurately measure the liquid level of liquid or powdery materials and output the result as a changing electrical signal to facilitate subsequent processing. Capacitive level gauge uses the capacitance effect to measure the capacitance of the liquid. Capacitive level gauge is suitable for measuring the level of various liquids and powdery materials. The core component of the

capacitive level gauge is the sensing rod, which can be multiple, installed on the wall of the liquid level container, and the distance between the two ends is the same. When the liquid level rises, the dielectric constant (e. g. liquid) in the container will increase, and the value of the capacitance will also increase accordingly. The output signal of the capacitive level gauge is the capacitance value between the liquid level in the container and the sensing rod, so the measurement of the liquid level can be realized.

capacitive level gauge is widely used in chemical industry, petroleum, water treatment and other fields. For example, in the chemical process, the capacitive level gauge can accurately measure the liquid level of the reactor to avoid safety hazards such as overflow and explosion. In the petroleum industry, capacitive level gauges can be used to measure the level of oil tanks to ensure the safety of oil storage. In the field of water treatment, capacitive level gauges can be used to accurately measure the water level in the water tank to avoid the danger caused by the water level being too low or too high.

capacitive level gauge, as an accurate and reliable liquid level measuring device, is widely used in industrial production, chemical industry, petroleum and other fields. Although errors may still occur in actual operation, it is characterized by high accuracy, good repeatability, high reliability, and low maintenance costs, and will continue to be widely used in the future.
