RDCL 80 GHz Radar Level Transmitter RDCLRD

A. Product Overview

The RDCL 80 GHz Radar Level Transmitter RDCLRD is an industrial level measurement instrument designed to measure the level of liquids and solid materials without making physical contact with the measured substance.

The transmitter uses Frequency Modulated Continuous Wave (FMCW) radar technology to provide continuous and accurate level measurement in industrial environments.

Operating in the 80 GHz frequency range, the radar transmitter offers high measurement resolution, a narrow beam angle and minimal interference from surrounding tank structures.

With a measuring range of 0.1 to 65 meters and a specified accuracy of ±1 mm, the RDCLRD radar level sensor is suitable for applications requiring precise level monitoring.

The instrument features a compact lens antenna, IP67 protection and RS485 communication for integration with industrial automation systems. A 4 to 20 mA output is also described as an available option in the referenced product family.

It can be used for monitoring water levels, chemical storage tanks, wastewater treatment systems, cement silos, fly ash silos and other industrial storage applications.

Important Technical Specifications

B. Working Principle

The RDCL RDCLRD 80 GHz Radar Level Transmitter operates using Frequency Modulated Continuous Wave (FMCW) radar technology.

The transmitter generates high frequency electromagnetic radar signals and directs them toward the surface of the liquid or solid material inside a tank, silo or storage container.

When these radar signals reach the material surface, they are reflected toward the transmitter's receiving antenna.

The instrument measures the frequency difference between the transmitted radar signal and the reflected signal. An internal signal processing system analyzes this frequency difference to calculate the distance between the sensor and the measured material surface.

Using the measured distance and the configured tank height, the transmitter determines the actual material level.

Step-by-Step Working Process

1. Radar Signal Transmission: The transmitter emits high frequency radar signals toward the material surface.

2. Signal Reflection: The signals are reflected by the surface of the liquid or solid material.

3. Echo Reception: The antenna receives the reflected radar signals.

4. Signal Processing: The internal electronics analyze the frequency difference using FMCW technology and signal processing algorithms.

5. Level Calculation: The transmitter calculates the distance and determines the corresponding material level.

6. Output Communication: The measured level information is transmitted to a compatible PLC, monitoring system or industrial control device through the configured communication output.

Because the measurement process does not require physical contact with the material, the radar transmitter is especially useful for applications involving corrosive liquids, viscous substances and industrial bulk materials.

C. Why Is the RDCL 80 GHz Radar Level Transmitter Used?

The RDCLRD radar level transmitter is used for accurate, reliable and continuous level measurement in industrial applications where conventional contact measurement devices may be unsuitable.

1. Non-Contact Level Measurement

The radar transmitter measures liquid and solid material levels without touching the measured substance. This reduces mechanical wear and minimizes direct exposure to potentially corrosive process materials.

2. High Measurement Accuracy

The device offers a specified measurement accuracy of ±1 mm, making it suitable for applications requiring precise level monitoring and inventory management.

3. Long Measurement Range

With a measuring range of up to 65 meters, the transmitter can be used in large industrial tanks, storage vessels, reservoirs and silos, subject to application conditions.

4. Narrow Beam Angle

The 6° radar beam angle helps reduce interference from tank walls, internal structures and surrounding obstacles.

5. Industrial Automation Integration

RS485 communication allows the transmitter to connect with compatible industrial monitoring and control systems. A 4 to 20 mA output option can support integration with analog instrumentation systems.

6. Reduced Maintenance Requirements

Because the device uses non-contact measurement technology, it does not rely on floats or other mechanical measuring components that contact the process material.

7. Suitable for Different Industrial Materials

The transmitter is designed for measuring both liquids and solid materials, making it useful across chemical processing, water management, environmental monitoring and bulk material storage operations.

D. Suitable Buyers

The RDCL 80 GHz Radar Level Transmitter RDCLRD is suitable for industries and professionals requiring continuous liquid or solid level monitoring.
