ndustrial Gas Detector SR-918 Series: Safety, Automation & Compliance
Industrial environments like chemical plants, school boiler rooms, hotel kitchens, and fuel stations are high-risk zones for combustible gas leaks. Installing an industrial gas detector is not simply a matter of placing the device—it requires precise selection, power compatibility, and integration with safety systems. Recent site reviews for 37 B2B clients revealed three common pitfalls in over 80% of industrial setups:
1. Power Mismatch Issues
Industrial gas detectors must match site power specifications. Installing a 12-24V model in a site with only 220V outlets (or vice versa) leads to additional power modules and high failure rates. Ensuring correct voltage is the first step in safe deployment.
2. Inability to Activate Solenoid Valves
Many industrial regulations require automatic gas cut-off upon alarm. However, inexpensive detectors often lack solenoid valve activation capability, making this feature ineffective. Choosing a model like SR-918NC or SR-918DVY-C ensures full automation.
3. Lack of Relay Output for System Integration
Linking a detector to exhaust fans, explosion-proof ventilators, or fire alarm control panels requires dry-contact relay outputs. Many entry-level models omit this feature, causing expensive retrofitting later. Selecting the right model from the start reduces long-term costs.
SR-918 Series Functional Comparison Table
We analyzed all 8 models of the SR-918 series across six key parameters: LCD display, voice alarm, solenoid valve activation, relay output, power type, and gas species.
| Model | Gas Species | Power | LCD Display | Voice Alarm | Solenoid Valve | Relay Output |
|---|---|---|---|---|---|---|
| SR-918NC | Combustible Gas | 12-24V | No | No | Yes | Yes |
| SR-918NS | Combustible Gas | AC90-240V | No | No | No | No |
| SR-918NV | Combustible Gas | AC90-240V | No | No | Yes | No |
| SR-918NSY | Combustible Gas | AC90-240V | Yes | Yes | No | No |
| SR-918NVY | Combustible Gas | AC90-240V | Yes | Yes | Yes | No |
| SR-918DVY-C | Combustible Gas+CO | 12-24V | Yes | Yes | Yes | Yes |
| SR-918DSY | Combustible Gas+CO | AC90-240V | Yes | Yes | No | No |
| SR-918DVY | Combustible Gas+CO | AC90-240V | Yes | Yes | Yes | No |
Core Selection Logic
- Need to cut gas + activate exhaust? → Choose a model with relay output (NC, DVY-C).
- Low-voltage DC site (e.g., gas meter rooms)? → Select 12-24V series.
- Fire safety compliance with voice & light alarms + automation? → SR-918DVY-C is the only full-featured model.
Industrial Solutions by Sumring: One Choice for Five Years of Safety
Even with a functional comparison, industrial selection requires expertise. Factors include explosion-proof ratings, installation location, solenoid valve compatibility (normally open/closed), and wiring specifications. Saiyuanxin provides complete solutions, not just devices.
1. On-site Survey
Response within 2 hours for Shenzhen and surrounding areas. Measurement of voltage, gas type, and cable length ensures proper system design.
2. Model Matching
Based on the need for exhaust fans or integration with the fire control room, we recommend the appropriate SR-918 model and provide matched explosion-proof solenoid valves and junction boxes.
3. Integrated System Testing
After installation, simulated gas leaks confirm the alarm → valve shutoff → exhaust operation chain executes within 3 seconds.
4. Custom Services
- Custom logo for batch projects
- Modified alarm thresholds
- Third-party verification reports
Successful Projects
- Shenzhen Gas Group canteens
