The SA-5100D-CH4 is a highly sensitive methane sensor using non-dispersive infrared (NDIR) technology for hydrocarbon absorption detection. It features a diffusion captive open path optical chamber.

• Electrical: Operates on 10-30 VDC, nominal 24VDC, with a power consumption of 2.5 watts.
• Environmental: Functions in temperatures from –40°F to +158°F (-40°C to +70°C) and humidity from 15-95% non-condensing.
• Mechanical: Constructed with electropolished 316 stainless steel, dimensions are 3.4” OD, 8.1” L (86.5mm OD, 206 mm L).
• System: T90 response time is less than 90 seconds, with a 2-year warranty.

Suitable for hazardous locations: Class I; Division 1; Groups BCD and Class I Zone 1; Group IIB +H2.

• Various junction boxes, local display, alarm relay module, LoRaWAN and MODBUS transmitter modules, and a magnetic wand for calibration.

• Digital display with real-time readings and full script user interface.
• System status indicators: Green for normal, Amber for level 1 warning, Red for level 2 warning, Blue for fault condition.

• Includes diagnostics for zero stability, response time, span drift, signal stability, and signal strength.

Provides response factors for various gases, with methane having a factor of 1.0.
