Why JWrada® Radar Level Transmitters Are More Than Just “Radar”
In the field of industrial automation, radar level measurement is no longer a new technology.
The real concerns of engineers have never been whether a level can be measured, but rather:
- Can the measurement remain stable under high temperature, steam, dust, and foam conditions?
- Will signal loss or fluctuations occur when measuring low dielectric materials or vessels with complex internal structures?
- After commissioning, does debugging, maintenance, or firmware upgrading still require frequent on-site visits?
- In hazardous areas, does the instrument truly provide reliable explosion-proof and corrosion-resistant performance?
Starting from real industrial field requirements, Shenzhen Jiwei Automations Ltd has developed a complete JWrada® radar level transmitter product portfolio. Through the clear differentiation between the PRO Series and the MINI Series, Jiwei addresses both extremely demanding industrial conditions and cost-effective standard applications.
I. PRO Series Radar Level Transmitters
Designed for Complex Conditions — Not Just Impressive Specifications
1. 80GHz Millimeter-Wave Radar: An Engineering Necessity, Not a Gimmick
The Jiwei PRO Series adopts 80GHz FMCW millimeter-wave radar technology and is equipped with multiple lens antenna diameters, offering a maximum measuring range of up to 150 meters.
In real industrial applications, this configuration delivers clear engineering benefits:
- Narrow beam angle, reducing interference from tank walls, internal structures, and supports
- Highly concentrated signal energy, improving sensitivity to low dielectric powders and bulk solids
- Zero blind zone, ideal for high-level, full-bin, and top-mounted measurements
As a result, the PRO Series provides clear advantages over traditional radar or ultrasonic instruments in large silos, reactors, and high-level storage vessels.
2. Adaptive Echo Learning Algorithm: Let the Instrument Adapt to the Process
In real industrial environments, radar signal interference is rarely caused by a single factor. Instead, it typically results from the combined effects of multiple conditions, such as reflections from multi-layer material surfaces, dynamic level changes caused by agitation or filling processes, and the influence of steam, dust, or foam on electromagnetic wave propagation. These disturbances are often random and continuously changing, representing one of the primary challenges to long-term stable radar measurement.
To address these challenges, the PRO Series radar level transmitters are equipped with Jiwei’s self-developed adaptive echo learning algorithm. By continuously analyzing and modeling on-site echo signals, the instrument can automatically identify false echoes, intelligently separate multiple echo layers, and dynamically track and lock onto the true target echo. During operation, the device continuously updates its echo characteristics without requiring frequent manual re-calibration, significantly enhancing measurement stability and long-term reliability.
3. Bluetooth and Cloud Platform: Eliminating the Need for Constant On-Site Access
The PRO Series radar level transmitters are equipped with HART communication as standard and feature an integrated Bluetooth 5.0 module. Combined with the “Jiwei Smart Control®” WeChat mini program and cloud data services, the system supports:
- Wireless on-site commissioning
- Parameter configuration
- Real-time status monitoring
- Online firmware updates
- Remote process adjustment
- Remote parameter modification
- Fault code diagnostics
- Real-time EFT echo curve monitoring
In practical applications, when abnormal conditions occur, Jiwei engineers can connect via cloud servers and provide one-on-one remote commissioning support with on-site personnel. This greatly reduces downtime and maintenance costs, particularly for remote facilities and overseas projects.
4. High Temperature, Explosion Protection, and Corrosion Resistance as Standard Capabilities
The PRO Series radar level transmitters are designed for long-term operation at temperatures up to 220°C and feature a complete, standardized explosion-proof protection system covering both gas and dust hazardous environments. The available explosion protection ratings include Ex db IIC T6 Gb, Ex ia IIC T6 Ga, Ex tb IIIC T80°C Db, and Ex ia IIIC T200 80°C Da, fully meeting the stringent safety requirements of petrochemical and chemical industries.
Structurally, the PRO Series adopts a professional corrosion-resistant and pressure-sealed design, with key components incorporating PTFE protective diaphragms. This design significantly enhances resistance to corrosive media and sealing reliability. Consequently, the instruments are suitable not only for strong acids and alkalis but also maintain stable performance under high steam, heavy dust, foam, condensation, and other harsh industrial conditions, effectively reducing maintenance frequency and extending service life.
II. MINI Series Radar Level Transmitters
Cost-Effective Without Compromising Core Capabilities
1. Compact Design for a Wide Range of Standard Applications
The MINI Series JWrada-2x radar level transmitters are compact, cost-effective intelligent instruments based on 80GHz FMCW radar technology, with a maximum measuring range of 30 meters and accuracy up to ±1 mm. They are well suited for:
- Hydrology and water level monitoring
- Municipal and environmental projects
- Small tanks, open channels, and reservoirs
- Simple bulk solids level measurement
In many applications, they serve as an ideal replacement for ultrasonic level transmitters.
2. Optional Display for More Intuitive On-Site Commissioning
The MINI Series radar level transmitters can be optionally equipped with a simple local display. During installation and commissioning, measurement values and operating status can be read directly without additional handheld devices or host systems. This feature enables construction and commissioning personnel to quickly verify instrument status, reduces commissioning complexity, minimizes human error, and improves overall installation efficiency—particularly beneficial for water and municipal projects with distributed measurement points.
3. MINI Series with Full Smart Capabilities
Despite their cost-effective positioning, MINI Series radar level transmitters are still equipped with an integrated Bluetooth 5.0 module, supporting:
- Wireless commissioning via WeChat mini program
- Parameter configuration
- Remote monitoring
- Remote firmware upgrades
- Fault code viewing
- Real-time EFT echo curve monitoring
When necessary, Jiwei engineers can also provide remote technical support through the cloud platform.
4. Lightweight and Weather-Resistant Design for Outdoor Operation
- Nylon plastic or stainless steel housing options
- Lightweight, UV-resistant, and weatherproof
- Especially suitable for hydrology, water utilities, and outdoor level monitoring applications
III. Why JWrada® Radar Level Transmitters Are Truly “Engineering-Oriented”
The strengths of Jiwei radar level transmitters are not limited to technical specifications, but lie in their engineering-oriented design philosophy:
- Technology development driven by real industrial conditions
- Software, algorithms, and communication features designed for field usability
- Clear product positioning from high-end complex applications to basic use cases
- Systematic reduction of commissioning, maintenance, and lifecycle costs
This is precisely why JWrada® radar level transmitters have achieved long-term stable operation across petrochemical, chemical, water, energy, and industrial sectors—and continue to earn the trust of engineers worldwide.
