Wholesale CH4 Gas Detection System – Industrial Safety Solutions

Pump - Yes Humidity - Relative Certification - Calibration & Warranty Resolution - 0.01% for all gases Response Time - Less than 30 seconds to 95% step change Color - White Selective Methane Sensing: Utilizes a catalytic bead sensor element finely tuned for CH₄ detection, minimizing cross-sensitivity to other hydrocarbons or volatile organic compounds. Wide Detection Range: Monitors methane concentrations from 0 to 100% Lower Explosive Limit (LEL) with high accuracy (±2% LEL). Fast Response Time: T90 response time ≤ 15 seconds ensures rapid detection of rising methane levels. Intelligent Alarm Logic: Multi-Level Alarm: Factory-configurable high and low alarm points with distinct audible (≥ 85 dB) and visual (dual-color LED) alerts. Pre-Alarm Warning: Early warning stage at 20% of the high alarm setpoint for proactive intervention. Robust Construction: IP65-rated die-cast aluminum enclosure for dust and water ingress protection; suitable for harsh industrial atmospheres (−40 °C to 70 °C). Integrated Display & Controls: Backlit LCD shows real-time CH₄ concentration, status icons, and event logs; push-button interface for calibration, reset, and configuration. 4–20 mA & Modbus Output: Dual analog and digital communications enable integration with DCS, SCADA, or PLC systems for centralized monitoring and control. Self-Diagnostics & Calibration: Automated fault checks for sensor integrity, circuitry, and wiring; on-screen prompts guide field calibration with zero/span gas. Optional Relay Module: Adds up to four form C relays for remote alarm activation or system shutdown interlocks. Power Supply Flexibility: Accepts 24 VDC or 100–240 VAC with surge protection; low-power standby mode reduces energy consumption.
