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.

High-Quality Industrial and Commercial Gas Detector SD2100E Series - Reliable China Suppliers and Factory Solutions Suppliers, Factories

Product Overview The GTYQ-SD2100E/GTQ-SD2100E/GQ-SD2100E series point gas detector (hereinafter referred to as the detector) is an essential component for intelligent bus systems and split-wire products. This advanced gas detection system, developed by leading Chinese suppliers, works seamlessly with controllers to provide real-time monitoring of hazardous gases in various environments. The detector displays the gas concentration on-site and activates an acoustic and visual alarm signal once the concentration exceeds predetermined limits. The controller allows users to monitor the detector's normal, fault, or alarm statuses and enables adjustments such as zero calibration, concentration calibration, and high/low limit alarm values through either the controller or infrared remote control. Application This gas leak detector is widely utilized across various industries, including petroleum, chemicals, environmental protection, metallurgy, refining, gas distribution, biochemical medicine, and agriculture. Manufactured in China, our factory ensures high-quality production to meet strict safety standards, making it an ideal choice for businesses looking for reliable gas detection solutions.

Frequently Asked Questions

What communication systems is the 2100E gas detector compatible with?

The 2100E is adapted to both bus systems and 4-20mA split line systems, making it highly flexible and convenient for various system designs and future expansions.

Can the sensor module be replaced without replacing the entire unit?

Yes, the sensor modules are designed to be replaceable. This significantly reduces long-term use and maintenance costs, as only the sensor needs to be swapped rather than the entire device.

How can the device be operated on-site without opening the enclosure?

The 2100E features an infrared remote control function, allowing operators to perform on-site adjustments and operations without the need to open the lid, ensuring safety and convenience.

Does the gas detector support automatic alarm or ventilation control?

Yes, the unit includes its own built-in linkage control output, which can directly trigger sound and light alarms or control fans and valves on-site when a gas hazard is detected.

How does the built-in temperature detection function benefit performance?

The built-in temperature detection function ensures that the gas concentration readings remain accurate and reliable across a wide range of environmental temperature conditions, improving overall detection effectiveness.

What accessories and documents are included in the product package?

Each unit comes with a product manual, factory inspection report, certificate of conformity, mounting plate, and mounting fittings. Before use, inspect the product for any scratches, verify that all labels are intact and legible, and confirm all accessories are present.
