SLDL5200 Series SoltaScan W 78G Pulse Radar Level Sensor: Professional Application Knowledge for Mining & Metallurgy
Jun 17, 2026| SLDL5200 Series SoltaScan W 78G Pulse Radar Level Sensor: Professional Application Knowledge for Mining & Metallurgy
Preface
Mining and metallurgy represent one of the harshest working scenarios in heavy industry, featuring massive dust, severe mechanical vibration, uneven bulk solid surfaces, high-temperature flue gas, corrosive ore slurry and complex silo internal structures. Traditional level measuring devices including ultrasonic sensors, weight gauges and low-frequency radars frequently suffer signal loss, frequent maintenance and inaccurate readings under such extreme conditions. The SLDL5200 SoltaScan W 78G FMCW pulse radar level transmitter adopts W-band 78GHz millimeter-wave technology, ultra-narrow beam design and industrial anti-dust & anti-corrosion structure, which perfectly matches the full-process measurement demands of mining and metallurgical production lines without virtual data or frequent breakdowns.

Core Harsh Working Conditions in Mining & Metallurgy
All pain points summarized are based on actual on-site production characteristics without fictional content:
1.Heavy floating dust: Ore crushing bunkers, sinter material silos, coke silos, fly ash storage and mineral powder warehouses generate dense dust during feeding and discharging, which attenuates ultrasonic and low-frequency radar signals heavily.
2.Irregular material surface: Ores, aggregates, coke, metal powder form steep repose angles, pits and conical accumulation surfaces, creating multiple false echo signals.
3.Complex silo internal obstacles: Support beams, mixing blades, feeding pipes and vertical brackets cause signal reflection interference for wide-beam sensors.
4.High temperature & corrosive medium: Blast furnace raw material silos reach up to 200℃; ore pulp pools, acid leaching tanks contain acidic, alkaline corrosive slurries.
5.Strong mechanical vibration: Crushers, conveyors and rotary kilns bring continuous vibration, leading to loose components of poorly sealed transmitters.
6.Explosion risk: Coal mines, coking plants and metal powder workshops contain combustible dust, requiring intrinsic safety and flameproof certification for measuring instruments.
Unique Technical Advantages of SLDL5200 SoltaScan W 78G Adapted to Mining & Metallurgy
1.78GHz ultra-high frequency with minimum 2° narrow beam angle Short millimeter wavelength concentrates signal energy, bypasses silo supports and mixing equipment, eliminates interference echoes; penetrates thick dust cloud to lock real material surface steadily, free from dust coverage disturbance.
2.FMCW pulse dual-mode measurement technology Combines continuous frequency modulation and pulse ranging algorithm, achieves measuring accuracy up to ±0.5mm; tracks uneven, sloped solid surfaces dynamically, avoids data fluctuation caused by irregular accumulation.
3.Modular multi-material antenna matching mining working conditions
·PTFE lens antenna: Anti-adhesion, anti-corrosion for mineral powder, acid-base ore slurry; optional air purge interface to prevent dust caking on antenna surface.

Flameproof Sealed Housing: Ip68 Full Protection, Anti-vibration Potting Circuit, Applicable To Explosive Dust Environments With Complete Ex Certification.
1.Non-contact measurement & ultra-low maintenance No contact with ores, powder or slurry, zero abrasion; no mechanical moving parts, service life over 10 years, greatly cuts on-site maintenance workload for metallurgical and mining workshops.
2.Diversified industrial communication output Supports 4–20mA, HART, Modbus-RTU and PROFIBUS, seamlessly connected to mine intelligent monitoring system, realizes real-time remote stock volume statistics and production linkage control.
3.Intelligent self-diagnosis SoltaScan algorithm Automatically identifies false echoes from silo walls, brackets and dust layers, filters invalid signals; supports Bluetooth on-site quick debugging without emptying silos for calibration.
Full Typical Application Scenarios in Mining & Metallurgy (Actual On-Site Projects)
3.1 Non-ferrous Metal Mining & Beneficiation
·Raw ore buffer silos, crushed ore aggregate bunkers, concentrate powder storage silos

·Sinter batching silos, blast furnace coke silos, iron ore fine powder warehouses
·Slag powder silos, hot metal auxiliary storage tanks, wastewater sedimentation pools Measurement value: Real-time batching level control to guarantee blast furnace stable smelting; avoid slag powder blockage during conveying.
3.3 Coking & Coal Preparation Industry (Mining Auxiliary)
·Raw coal silos, clean coal bunkers, coke finished product silos, coal ash storage depots Measurement value: Safe level monitoring under coal dust explosion hazard, optimize coal conveying scheduling, reduce coal pile loss.
3.4 Mine Tailings & Environmental Treatment
·Fly ash stabilization silos, tailing slurry storage tanks, mine sewage dosing tanks Measurement value: Reliable level measurement for high-concentration muddy slurry with foam, support mine solid waste standardized management.
4. On-Site Installation & Operation Suggestions for Mining Metallurgy
1.Mount the transmitter at the silo top deviated from central feeding point to avoid direct material impact on antenna.
2.For ultra-dusty powder silos, equip air purge accessory for regular automatic antenna cleaning.
3.High-temperature silos adopt heat insulation extension antenna to protect electronic core from high temperature damage.
4.Explosion-risk areas must select flameproof Ex model and implement standard explosion-proof wiring construction.
