Key Features & Advanced Protection

Engineered for uncompromising safety in volatile environments, this fixed combustible gas transmitter integrates precision detection technology with rugged physical protection. Facility operators require instrumentation that not only identifies hazards but does so with unwavering accuracy and minimal false alarms. Industrial safety protocols demand equipment that leaves no room for error, and this unit is specifically calibrated to offer a stable baseline, reducing the frequency of manual recalibrations while maximizing facility uptime. The core advantages of this detector are designed to address the most complex atmospheric monitoring challenges in hazardous zones.

  • Comprehensive Measurement Capabilities: Designed to 6. Continuously measure the gas concentration in the air, ensuring that the 1. EX measurement range is 0 to 100%. Furthermore, 7. The Gas Transmitter can detect LEL/CO/ H2S/ H2/ SO2/ NH3/ NO/ NO2/ CL2/ O3/ O2/ CO2/ PH3/ HCL/ HCHO/ C6H6,etc.., providing versatile facility monitoring across diverse chemical profiles.

  • Advanced Detection Core: Built with 3. Imported sensors, high sensitivity and high reliability, this device captures minute concentration shifts instantly, granting crucial lead time for emergency response teams to mitigate risks.

  • Rugged Environmental Resistance: The 4. Gas Detector is waterproof dustproof design side, working humidity range 15-95% (RH), built to resist electromagnetic interference and physical degradation over time in demanding industrial settings.

  • Verified Safety Compliance: Fully backed by 5. CNEx explosive proof, China official certificate, and aligned with international safety benchmarks, ensuring strict regulatory compliance for highly volatile production areas.

  • Secure Mounting & Maintenance: The 2. Installation is triangle hole design, more stable against structural vibrations caused by heavy machinery. It supports flexible wall or pipeline mounting, complemented by infrared remote calibration options for cover-free, non-intrusive maintenance.

  • Streamlined System Integration: Features direct output options including 4-20mA, RS485, and relay switches, allowing immediate linkage with PLC and DCS control networks for automated multi-level alarm configurations and active ventilation control.

Technical Data

When integrating safety instrumentation into critical infrastructure, precise operational parameters are non-negotiable. The MT003 model is engineered to deliver consistent, uninterrupted monitoring under demanding physical and thermal conditions. Powered by a dependable DC24V supply, this continuous operation unit utilizes a highly responsive catalytic gas sensor that achieves a responding time of ≤40s, ensuring that safety mechanisms are triggered without delay. The robust Exd II CT6 housing provides intrinsic safety across a wide temperature span of -20℃ to 50℃, while preventing moisture-related failures in environments with 10 to 90%(RH)No condensation. Whether deploying a two-wire or three-wire system (with combustible gas utilizing the two-wire setup), facility managers can rely on these verified specifications to maintain stringent environmental control. At a compact outline dimension of 150mm×190mm×75mm and a manageable weight of ≤1.5kg, the unit offers a streamlined footprint without sacrificing heavy-duty performance. Below is the comprehensive breakdown of the device's operational capabilities, electrical requirements, and physical dimensions to assist your engineering team in efficient facility integration.

Comprehensive Applications & Manufacturer Support

Securing vulnerable industrial sectors requires adaptable, proven, and highly responsive detection technology. This fixed combustible gas transmitter is widely deployed across high-risk environments, including natural gas pipelines, petrochemical processing facilities, commercial gas stations, and hospital utility rooms. Its ability to function reliably in confined spaces makes it an essential component for 24-hour online monitoring, actively preventing catastrophic leaks before they escalate into critical emergencies. When you handle the device, the substantial weight of the tactile, heavy-duty metallic enclosure and its precision-machined joints immediately convey an industrial-grade durability meant to survive years of exposure to corrosive elements. The audible click of the secure relays and the clear visual indicators provide immediate sensory confirmation of the unit's active protective status.

Beyond the physical hardware, long-term operational security is backed by comprehensive manufacturer support. As a direct source factory, we provide extensive OEM and ODM customization services tailored to specific project requirements, allowing for branded solutions and specialized calibration ranges. Every detector is supported by a solid 12-month warranty, ensuring peace of mind and sustained performance. Procurement teams benefit from expedited lead times, streamlined supply chains, and dedicated professional technical guidance. From initial site assessment and comprehensive wiring instructions to post-installation calibration kits and troubleshooting, our end-to-end service guarantees that your safety infrastructure remains operational, compliant, and highly effective.
