What gas safety products does Shield manufacture?

Shield designs and manufactures household combustible gas detectors, industrial and commercial point-type combustible gas detectors, gas alarm controllers, portable and 4-in-1 multi-gas detectors, and solenoid gas shut-off valves. The portfolio covers more than 80 marketable models that can be combined into complete detect-alarm-shut-off systems.

Is the Lower Explosive Limit (LEL) the same as the alarm set point?

No. The LEL is the lowest gas concentration in air that can ignite. Combustible gas detectors read in %LEL and trigger alarms well below that limit. Alarm set points are commonly configured in the range of about 20-25% LEL for the first alarm and up to about 50% LEL for the second alarm, but the final values must follow the standard that applies in your country and project.

Why do oxygen detectors display %VOL instead of ppm?

Normal air contains about 20.9% oxygen by volume, so oxygen deficiency or enrichment is measured in percentage by volume (%VOL). A ppm scale is designed for trace-level toxic gases and would be impractical for oxygen monitoring during pipe welding or confined-space work.

How does a gas detector work with a solenoid shut-off valve?

When the detector or gas alarm controller registers a concentration above the alarm value, it emits an audible and visual alarm and sends a linkage signal that closes the solenoid gas shut-off valve. Shield shut-off valves such as the JYFJS-011 series require manual reopening, so gas supply is only restored after the cause of the leak has been checked.

Does Shield support OEM and ODM orders for distributors?

Yes. Shield supports OEM and ODM cooperation. Branding, packaging, documentation and project-specific configuration such as target gas, alarm values and linkage outputs are reviewed and confirmed with our engineering team before sampling and mass production.

Which certifications do Shield products hold?

Applicable Shield products have been awarded China's mandatory 3C certification, and the company holds more than 40 patents. For export projects, our sales engineers confirm the test reports and compliance documents required in the destination market before an order is placed.

Product Overview

The GTYQ-SD2100E/GTQ-SD2100E/GQ-SD2100E series point gas detector, designed for intelligent bus systems and split-wire products, is a reliable solution for gas alarm detection. This advanced detector integrates seamlessly with controllers to form an efficient gas monitoring system. It provides real-time detection and display of target gas concentrations in the operating environment. When gas levels surpass the defined limits, the controller activates acoustic and visual alarm signals. Users can monitor the detector's normal, fault, or alarm status, and conveniently set parameters such as zero calibration, concentration calibration, and high/low limit alarm values via the controller or infrared remote control. Our products are manufactured in China, ensuring high quality and reliability, making us a preferred choice among suppliers in the market.

Application

This versatile leak detector is extensively utilized across various industries, including petroleum, chemical, environmental protection, metallurgy, refining, gas distribution, biochemical medicine, and agriculture. As a leading factory in China, we are committed to providing top-notch gas detection solutions tailored to meet your industry needs.
