80GHz Explosion Proof Radar Level Gauge with High Accuracy and Connectivity

Hazardous areas, extreme ranges, high pressures and the demand for accurate, connected data: the QWRD80G605 80GHz radar level gauge was designed to handle all of them at once. It brings explosion proof certification, 1mm resolution, a 0.3-70 m range, IP67/IP68 protection and Bluetooth, NB-IoT and 4G connectivity to the most demanding tank and silo applications.

Why Do You Need an 80GHz Explosion Proof Radar with Smart Connectivity?

Three requirements increasingly converge in modern plants. First, safety: tanks and silos holding flammable products sit in hazardous areas where every instrument must be certified explosion proof. Second, performance: vessels are getting taller and processes more demanding, requiring radar that measures accurately at long range through dust and vapor. Third, connectivity: operators want level data on their phones, dashboards and cloud platforms, not just on a local display. Choosing an 80GHz radar gauge that is simultaneously explosion proof, accurate to 1mm and wirelessly connected solves all three in a single instrument. It protects the plant, measures precisely over ranges up to 70 meters, and delivers the data where decisions are made, without multiple devices and complex integration.

Working Principle: 80GHz FMCW Radar with Certified Protection

The QWRD80G605 uses 80GHz FMCW (frequency-modulated continuous wave) radar technology: the gauge transmits a frequency-swept microwave signal and measures the frequency difference of the reflected echo to calculate the distance to the product surface with 1mm resolution. The 80GHz band provides a narrow, focused beam that avoids false echoes and penetrates dust and vapor, while the FMCW processing delivers stable readings even with turbulent or weak-reflecting surfaces. The electronics are housed in an explosion proof certified enclosure with IP67/IP68 ingress protection, the gauge is rated for pressures up to 40 bar, and the measured value is available through analog output plus Bluetooth, NB-IoT or 4G wireless connectivity for remote monitoring.

SEO FAQ

Q1: What makes 80GHz radar better for silos and tanks?

The 80GHz frequency band gives radar level gauges three practical advantages. First, the beam angle is much narrower than at lower frequencies, so the instrument measures the product surface directly below it instead of picking up false echoes from silo walls, beams and internal structures. Second, the high frequency reflects more strongly from powders, grains and low-dielectric liquids, giving a stronger echo. Third, the small antenna required at 80GHz fits easily into existing nozzles and is lighter to mount on tall structures. These advantages make 80GHz radar especially valuable for tall silos, dusty atmospheres and confined nozzle installations, where lower-frequency radars struggle.

Q2: What does the explosion proof certification allow me to do?

Explosion proof certification allows the QWRD80G605 to be installed in hazardous areas where flammable gases, vapors or dusts may be present, in compliance with safety regulations. The instrument is designed to contain any internal ignition so that it cannot ignite the surrounding atmosphere, and it is certified according to the applicable explosion protection standards. This means you can use the gauge on fuel storage vessels, chemical silos and other hazardous installations where non-certified instruments are prohibited. When ordering, please provide your area classification and the applicable certification requirements for your region so we can confirm the correct certified version is supplied.

Q3: What is the maximum measuring range?

The QWRD80G605 measures from 0.3 meters to 70 meters, covering everything from small process tanks to the tallest industrial silos. The minimum range of 0.3 meters means the gauge also works in relatively shallow vessels where some radars have a large blind zone. The maximum range of 70 meters handles the tallest grain silos, cement silos and storage towers found in industry. When ordering, specify your vessel height and the expected minimum and maximum levels so the gauge is configured with the appropriate range and signal processing for your application, ensuring the best accuracy and reliability.

Q4: How does the wireless connectivity work and what do I need?

The QWRD80G605 offers Bluetooth, NB-IoT and 4G connectivity options. Bluetooth connects the gauge to a smartphone or tablet app for local configuration, commissioning and data reading within a short range. NB-IoT and 4G transmit the level data over cellular networks to a cloud platform or central server, enabling remote monitoring from anywhere; NB-IoT is a low-power option for frequent small data reports, while 4G provides broader coverage and higher data rates. For wireless operation you need a SIM-enabled data plan (for 4G or NB-IoT) and, if desired, access to a cloud platform. Our engineers can assist with platform configuration and data integration.
