What is the lifespan of the GLT501 sensor?

With proper installation and use within specified parameters, the GLT501 is designed for long-term service (typically 5+ years). The high-quality silicon core and anti-aging cable materials ensure minimal drift over time.

Can I customize the output signal if my system uses 0-10V?

Absolutely. We offer multiple output options: 4-20mA, 0-5V, 0.5-4.5V, 0-10V, and RS485. You can select the output that best fits your controller or data logger.

Can I connect this sensor to my smartphone or cloud system?

Yes, by choosing the RS485 Modbus output, you can easily connect the GLT501 to a wireless gateway (GPRS/4G/LoRa) for remote monitoring on your phone or PC dashboard.

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:Can the GLT501 be used for measuring liquids other than water

Yes. While it is primarily used for water, the 316L stainless steel housing and optional PUR/PVDF cables allow it to measure compatible liquids like diesel, oil, and certain mild chemicals. Please consult our technical team for specific media compatibility.

Q:What is the maximum measurement range available for the GLT501?

The GLT501 is highly versatile, with ranges starting from 0-1m up to 500mH2O. We can customize the cable length and sensor range to match your specific tank or well depth.

Q:How does the sensor compensate for changes in atmospheric pressure?

Our cables are equipped with a built-in vent tube. This tube connects the internal sensing element to the surface air, allowing the sensor to automatically subtract atmospheric pressure and provide an accurate hydrostatic level reading.

Q:Is the installation complicated?

Not at all. It is a "drop-in" sensor. Simply submerge the probe into the liquid and fix the cable at the top of the tank or well. No complicated mounting or calibration is required for initial setup.

Q:Is this sensor certified for use in hazardous areas?

The GLT501 series is designed for industrial reliability and is available with CE and RoHS certifications. For specific explosion-proof (ATEX/Exia) requirements, please check our specialized explosion-proof models in the GLT series.
