General Description
Capacitive Level Sensor, also known as liquid level (material level) transmitters, are applicable to the measurement of liquids, oils, solids, and interfaces. They feature a static design devoid of moving components, which significantly boosts reliability. Unaffected by water vapor, dust, or condensation, these sensors offer the benefits of stable, dependable long-term operation, high sensitivity, excellent linearity, as well as high temperature and pressure resistance. The intelligent liquid level meters operate on a two-wire (loop-powered) system, providing a 4 – 20mADC measurement signal. They are user-friendly in terms of adjustment and support wireless transmission, 485 transmission, and more. Consequently, they find extensive application across multiple sectors, including petroleum, chemical, metallurgy, electric power, paper, and pharmaceuticals.
Feature
- Modbus protocol is easy to integrate.
- Simple structure without any movable or elastic components, so it has high reliability and minimal maintenance. Under normal circumstances, it is not necessary to carry out routine large, medium and small maintenance.
- A variety of signal outputs are convenient for different system configurations.
- Suitable for level measurement of high temperature and high pressure containers, and the measured value is not affected by the temperature, specific gravity of the liquid to be measured, and the shape and pressure of the container.
- It is especially suitable for the measurement of strong corrosive liquids such as acid and alkali.
- Perfect overcurrent, overvoltage and power supply polarity protection.
- Wireless level sensor has wireless remote transmission function.
- Can measure any medium.
