3、 Core advantages of the product

1. Accurate and stable measurement: The coaxial probe precisely restricts the microwave transmission, eliminates the interference of steam, foam, dust, stirring disturbance and other working conditions, and the measurement is not affected by the change of medium density, viscosity, conductivity, and can still output signals stably in low dielectric constant media (such as diesel, toluene). Designed with a small range of 600mm and an accuracy of ± 2mm, it is far superior to conventional liquid level instruments and suitable for high-precision control scenarios.

2. Strong adaptability to working conditions304 stainless steel probe and flange, suitable for various media such as water, oil, acid-base solutions, organic solvents, etc; The operating conditions of 50 ℃ room temperature and 0.007-0.12MPa micro positive pressure cover the vast majority of industrial conventional containers, and operate stably in the vacuum to micro positive pressure range without measurement blind spots or signal attenuation problems.

3. Intelligent, convenient and easy to useIntegrated HART communication protocol, supports remote range modification, zero calibration, and fault inquiry using handheld terminals or upper computers, without the need for cover opening operations. The on-site LCD display is intuitive and clear, supporting switching between Chinese and English. It can directly read real-time liquid level, output current, and working condition status, reducing the difficulty of on-site debugging and maintenance. Two wire wiring simplifies wiring, with 24VDC power supply compatible with industrial standard power supply, and plug and play installation.

4. Reliable, durable, and maintenance freeAll solid state electronic components, no mechanical wear parts, no risk of jamming or damage, and long-term operation without the need for cleaning, calibration, or component replacement. The IP67 protective shell resists moisture, dust, and slight corrosion, while the 304 material probe is resistant to medium erosion, maintaining long-term stability under complex working conditions and significantly reducing operation and maintenance costs.

5. Secure compatibility and adaptationStandard 4-20mA+HART output, compatible with various industrial control systems, no additional adapter module required. The top mounted design is suitable for various vertical containers, and the DN50 standard flange has strong universality, which can directly replace traditional instruments such as floats, capacitors, and magnetic level gauges. The modification does not require changing the container interface.
