Does it support remote configuration?

Yes, the GLT744 supports Bluetooth debugging (via smartphone app) and HART protocol, allowing you to configure and troubleshoot the sensor without opening the housing or climbing the tank.

What materials are available for corrosive environments?

The sensor face is typically made of PTFE or high-grade stainless steel, ensuring it can withstand strong acids, alkalis, and other aggressive chemicals.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company engaged in sensor, transmitter, and related instrument research, manufacturing, sales, and service. It reports ISO 9001-related certification, TS 16949 and ISO 20000 certifications, CE capability, ERP integration, three production lines, and documented procedures for supplier-service assessment, corrective actions, and complaint handling. It offers 3D design, ODM, and multiple customization models, but reports no new products during the past year, no SDK, and no OEM service for popular brands. Overseas service infrastructure is limited: no overseas warehouse, showroom, agent, or branch, and the stated overseas-service country count is zero. Financial records are referenced for recent years, but the provided slices do not disclose sufficient non-financial evidence to assess financial credibility. No customer cases are provided.

Supplier typeThe supplier is explicitly classified as a trading company. Its company description states that it conducts research, development, manufacturing, sales, and service for sensors, transmitters, and related instruments.

CertificationsThe supplier reports TS 16949, ISO 9001, and ISO 20000 certifications, along with an ISO 9001:2015 certificate and CE certification capability. These stated certifications provide explicit evidence of formal quality or management-system credentials.

After-Sales capabilityThe supplier reports documented and followed procedures for corrective and preventive actions and customer complaints. However, it has no overseas warehouse, showroom, agent, or branch, and the stated overseas-service country count is zero, indicating documented service processes but limited overseas service infrastructure.

Production capacityThe company describes itself as involved in manufacturing sensors and related instruments and reports operating three production lines. It also provides a stated water-level-sensor output figure, but the overall production scale and broader capacity are not sufficiently detailed for a complete capability assessment.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, and ODM services. This is direct evidence of broad product customization capability.

Product Q&A

Q:Why should I choose 80GHz radar over 26GHz radar?

80GHz radar has a significantly smaller beam angle. This means it can be installed in tanks with internal structures (like agitators) without interference. It also offers higher resolution and better performance in environments with heavy dust or steam.

Q:Can the GLT744 measure solid materials like cement or grain?

Yes! The 80GHz signal is excellent at reflecting off uneven solid surfaces. It is widely used in silos for cement, coal, plastic pellets, and agricultural grains.

Q:Is the sensor affected by foam on the liquid surface?

While thick, heavy foam can absorb some radar signals, 80GHz technology has much better penetration and sensitivity than ultrasonic sensors. For most industrial foams, the GLT744 can still provide a reliable level reading.

Q:What is the maximum measuring range?

The standard GLT744 supports ranges up to 30m/35m, but specialized versions can measure up to 120 meters for large-scale silos.

Q:How do I install it to ensure the best accuracy?

The sensor should be installed vertically, away from the tank wall (ideally at 1/4 to 1/6 of the diameter). Avoid installing it directly over the material inlet to prevent signal interference during filling.
