The Methane (CH4) Combustible Fixed Gas Detector (PX2-1-2-P3400-A-01) is designed for continuous monitoring of CH4 gases between 0-100% LEL and vapors in hazardous areas of zones 1 and 2. This detector is an explosion-proof fixed CH4 gas detector, based with a 4-20 mA / RS485 Modbus output signal, alarm and fault relays (all SIL2 certified) for monitoring the ambient air to detect toxic gases. This solution is ideal for those industries that need protection amongst hazardous CH4 gases such as occupational spaces, garages, process rooms, factories, combustion control rooms, refineries, gas stations, boiler rooms, and many others. Features Modular industrial design, protection class IP66 Ex db: Ignition protection for zone 1 and 2 Ex nR: Ignition protection for zone 2 Fast and Precise CH4 Measurements 0-100% LEL Compatible across a broad range of BMS Device can be used independent of control systems Individual configuration options available Robust against dust, humidity, and high/low temperatures Suitable for multiple industries and applications Certifications ATEX and IECEx certificates MSR-Electronic GmbH for electrical Ex protection SIL2 safety functions 4–20 mA, RS-485 and relay PX2-1 for zone 1 (and also suitable for zone 2): Type “Ex db” protection flame-proof enclosure PX2-2 for zone 2 Type “Ex nR” protection Enclosure: Additional FM and CSA certificates for Class I, Div. 1 Models PX2-1-2-E1110-C-01 - Gaslab Fixed Combustible Carbon Monoxide Detector PX2-1-2-E1130-E-01 - Gaslab Fixed Combustible Nitrogen Dioxide Detector PX2-1-2-E1194-A-01 - Gaslab Fixed Combustible Hydrogen Detector PX2-1-2-E1195-A5-01 - Gaslab Fixed Combustible Oxygen Detector PX2-1-2-I464-C-01 - Gaslab Fixed Combustible Carbon Dioxide Detector PX2-1-2-P3480-A-01 - Gaslab Fixed Combustible Propane Detector Warranty 1-year warranty - see CO2Meter Terms & Conditions.
