120 GHz Radar Level Transmitter, RS485

Dimension(Unit:mm)

Q1: What is a radar level transmitter?
A1: A radar level transmitter is a non-contact measurement instrument that uses microwave radar signals to determine the level of liquids or solids in tanks, wells, rivers, or other containers. It works by emitting high-frequency radar waves toward the medium's surface and measuring the time it takes for the reflected signal to return, allowing highly accurate and reliable level detection even in harsh environments such as steam, dust, or temperature variations.

Q2: What are the advantages of radar level transmitters over ultrasonic sensors?
A2: Radar level sensors offer several key advantages over ultrasonic sensors. They are not affected by temperature, pressure, vacuum, vapor, or dust, making them more reliable in harsh and changing environments. Radar technology also provides higher accuracy, longer measurement range, and better performance in confined or complex spaces where ultrasonic signals may be weakened or distorted. In addition, radar level transmitters can measure through foam, steam, or turbulent surfaces more effectively, ensuring more stable and consistent readings in industrial and environmental applications.

Q3: Can radar level transmitters be configured remotely?
A3: Yes, many modern radar level meters can be configured remotely. Depending on the model, setup and calibration can be performed via wireless Bluetooth or through digital communication protocols such as Modbus (e.g., RS485 interface). This allows users to adjust parameters, perform calibration, and monitor device status without direct physical access, which is especially useful for installations in confined or hard-to-reach locations such as wells, tanks, and underground chambers.

Tips: Why choose a high-frequency radar level transmitter?

A high-frequency radar level transmitter is preferred because it provides a very narrow beam angle, which improves targeting accuracy and reduces interference from tank walls or internal structures. Operating at higher frequencies, such as 120 GHz, also enables higher measurement precision, faster response, and better performance in confined or complex installations like water wells, narrow tanks, and small channels. In addition, it offers more stable readings in environments with steam, condensation, or surface turbulence, making it a reliable choice for demanding industrial and environmental level measurement applications.
